2019 South Side Sox Prospect Vote: Round 20

It came far too late for some, but Tyler Johnson is our No. 19 choice. Now, who is the 20th-best prospect in the White Sox system?

Go low: By the time the SSS Top 100 prospects are all written up, Johnson will find himself higher than No. 19.

We started this out trying to get as many names as possible on the ballot, but that only worked for about a dozen rounds before the results started to get a little wonky — no offense, Lincoln Henzman. So we’re back to the traditional five players out for each round, with combined 2018 stats to help you out in your decision-making process.

As we count down the SSS Prospect Vote, we’ll be counting up the overall list of Top 100 Prospects, with the SSS poll vote counting as a voice in the order of our official SSS Top 100.

Here’s how last year’s prospect vote wrangled out — all 42 picks, with an archive of every article in the 2018 series.

Voting results for Round 19

Tyler Johnson took the No. 19 spot with 79 of 182 votes (43.4%). Although many voters would see that ranking as too low (and, sneak preview, Johnson will move up at least a few spots in our Top 100 Prospects list), 19th still represents a jump of 12 spots from 2018.

Bryce Bush

Third Baseman
Age 19
2018 SSS poll ranking N/R
2018 High Level Great Falls (Rookie)
Overall 2018 stats 38 games ▪️ 3 HR ▪️ 18 RBI ▪️ .309/.396/.453 ▪️ 18 BB ▪️ 25 K

Most fans, including yours truly, believed that drafting Bush in the 33rd round of this year’s MLB Draft was more or less a goodwill gesture, as opposed to believing that he’d actually bypass a scholarship with the Mississippi State Bulldogs. After all, Bush was the second-rated prep prospect in Michigan, third-ranked prep third base prospect in the country, and the 52nd-ranked prep prospect in the nation, according to PerfectGame. However, I can speak for most fans in saying that I’m glad I was wrong! Close to a week after being drafted, Bush signed for $290,000, the equivalent of sixth-round money.

Bush dominated in his brief 14-game stint with the AZL White Sox by slashing .442/.538/.605, with one homer, eight RBIs, one stolen base, eight walks (15.4%) and just four strikeouts (7.7%) in 43 at-bats. Bush was promoted to Great Falls on August 3, and while he struggled a bit, he still did relatively well considering he was 2.5 years younger than league average. In 24 games totaling 96 at-bats for the Voyagers, Bush slashed .250/.327/.385 with two homers, 10 RBIs, three stolen bases, 10 walks (9.3%) and 21 strikeouts (19.4%). Combined with both teams for 2018, Bush slashed .309/.396/.453 over 139 at-bats, with three homers, 18 RBIs, four stolen bases, 18 walks (11.3%) and 25 strikeouts (15.6%).

Third base was the only position Bush played last year in rookie ball, and in 30 games he committed 12 errors. He has a good arm and has solid speed; his difficulties at the position may be attributable to becoming acclimated to the speed of the game. Even in Arizona and Great Falls, the game is exponentially quicker than it is at the prep level.

Bush will turn 19 in December, and at 6´0´´ tall and 200 pounds, he has the projectable build to hit the ball a long way. Eventually, if he doesn’t succeed at third defensively, Bush may end up moving to a corner outfield position or first base. Ideally, he’ll stick at the hot corner since that’s arguably the position with the weakest depth in the Sox system.

Bush has tons of charisma, with the intangibles to do what it takes to advance to succeed in professional ball. While my projections are for Bush to begin 2019 with Kannapolis, there will be concern whether or not he will be ready for full-season ball. If the Sox don’t feel he’ll be quite ready, the Sox likely would promote one of Johan Cruz, Micah Coffey, Jimmy Galusky or Travis Moniot instead. But don’t expect any of them to hold Bush off for long.

Jimmy Lambert

Right-handed starting pitcher
Age 24
2018 SSS poll ranking N/R
2018 High Level Birmingham (AA)
Overall 2018 stats 8-8 ▪️ 18 starts ▪️ 95 23 IP ▪️ 3.67 ERA ▪️ 110 K ▪️ 27 BB ▪️ 1.087 WHIP

Lambert, brother of top Colorado Rockies prospect Peter Lambert, improved in each of this three years with the Fresno State Bulldogs. In 15 starts in his junior season totaling 97 2⁄3 innings, he posted a 3.13 ERA, 1.20 WHIP. In those innings, he allowed 98 hits (.280 OBA) and 19 free passes (1.75 BB/9) while striking out 78 (7.19 K/9). With his control and solid four-pitch repertoire, the White Sox drafted him in the fifth round in 2016, signing him to a $325,000 bonus.

Lambert struggled with the AZL Sox and Kannapolis in 2016, perhaps because he was battling some fatigue. That year in 37 2⁄3 innings, he posted a high 5.26 ERA and 1.51 WHIP; he relinquished 44 hits (.288 OBA) and 13 walks (3.11 BB/9) but stuck out 43 batters (10.27 K/9). In 2017, returning to Kannapolis, Lambert excelled with a 2.19 ERA and 1.19 WHIP; however, he struggled at Winston-Salem, with a 5.45 ERA and 1.51 WHIP. Combined with both teams last year in 150 innings, Lambert posted a 3.84 ERA and 1.35 WHIP — allowing 163 hits (.282 OBA) and 40 walks (2.40 BB/9) while striking out just 102 (6.12 K/9) overall.

In 2018, Lambert put it all together, and was much tougher to hit. In 18 starts with Winston-Salem and Birmingham covering 95 2⁄3 innings, Lambert posted a 3.67 ERA and 1.09 WHIP in allowing 77 hits (.222 OBA), walking 27 (2.54 BB/9), and striking out 110 (10.35 K/9). Unfortunately, Lambert’s last game was in late July, as he suffered a strained left oblique. It’s possible he could’ve returned in late August, but the Sox opted not to take any chances.

Lambert’s velocity improved this year, as he transitioned from a two-seamer to a four-seamer that peaks at 96 mph. Lambert also also throws an above-average slider and curveball. His changeup is consistent; he held lefties well at Winston-Salem but he had a .321 OBA against them in a short sample size in Birmingham. Lambert currently ranks 21st among White Sox prospects according to MLB Pipeline, and is expected to return to Birmingham next year, since he only had five starts for the Barons in 2018.

Kodi Medeiros

Left-handed starting pitcher
Age 22
2018 SSS poll ranking N/R
2018 High Level Birmingham (AA)
Overall 2018 stats 7-7 ▪️ 27 games (22 starts) ▪️ 137 23 IP ▪️ 3.60 ERA ▪️ 141 K ▪️ 67 BB ▪️ 1.366 WHIP

When Medeiros finished his senior season with Waiakea H.S. (Hilo, Hawaii) with a 1.12 ERA, .178 OBA, and 16.7 K/9, PerfectGame ranked him as the sixth best prep prospect available in the 2014 MLB draft. Thus, it was no surprise when the Milwaukee Brewers selected him with their first round pick (12th overall). After receiving a $2.5 million signing bonus, Medeiros struggled with the AZL Brewers to the tune of a 7.13 ERA and 2.09 WHIP.

The following year, Medeiros bounced back somewhat with the Brewers’ A-affiliate Wisconsin, where he posted a 4.44 ERA and 1.28 WHIP in 93 1⁄3 innings, allowing 79 hits (.228 OBA) and 40 walks (10.0%) and striking out 94 (23.5%). However, he slid back in 2016 and 2017 for the Brewers’ A+ affiliates in Brevard County and Carolina, where in a combined 213 1⁄3 innings, Medeiros posted a 5.36 ERA, 1.56 WHIP, .266 OBA, 11.9 BB%, and 19.9 K%.

In 20 outings (15 starts) for AA Biloxi in 2018, Medeiros was enjoying his best minor league season to date — a 3.14 ERA and 1.31 WHIP over 103 1⁄3 innings, allowing just 90 hits (.234 OBA) and 45 walks (10.1%) while striking out 107 (24.0%). On July 26, Medeiros was traded along with right-handed pitcher Wilber Perez to the White Sox for closer Joakim Soria. After the trade, Medeiros struggled a bit in seven starts totaling 34 1⁄3 innings, posting a 4.98 ERA and 1.54 WHIP while allowing 31 hits (.250 OBA), 22 walks (14.5%) and 34 strikeouts (22.4%).

Medeiros currently ranks 19th among White Sox prospects according to MLB Pipeline. His fastball maxes out at 95-96 mph, with tailing action. He’s also got a plus slider which has a significant lateral break, and a solid changeup with good sink and fading action. However, he may have a more successful career as a closer for two reasons:

  1. He’s got a unique arm slot which makes it difficult for lefties to pick up: Lefties hit just .160 against him this year compared to .261 versus righties
  2. His control has been totally underwhelming: His career walk percentage in his four years of professional baseball is 11.4.

With that said, expect Medeiros to return to the Birmingham rotation to begin 2019.

Laz Rivera

Age 24
2018 SSS poll ranking 37
2018 High Level Winston-Salem (A+)
Overall 2018 stats 124 games ▪️ 13 HR ▪️ 61 RBI ▪️ .314/.361/.481 ▪️ 17-of-27 SB ▪️ 13 BB ▪️ 92 K

Rivera played for three different schools in his four-year college career: the University of Miami, Chipola JC (2015), and the Division II University of Tampa (2016-17). One thing is clear: The Miami resident excelled wherever he played. During that time, Rivera combined to slash .386/.442/.546 with 15 homers, 124 RBIs, 25 stolen bases, 40 walks (5.63%) and 66 strikeouts (9.28%) in 624 at-bats. After a typically successful season as a senior, Rivera wasn’t picked until the 28th round of the 2017 MLB draft.

His first assignment with the White Sox, upon receiving his $1,000 signing bonus, was with the AZL White Sox, and he didn’t disappoint. In 47 games (186 at-bats), Rivera slashed .296/.374/.446 with 12 doubles, five triples, two homers, 24 RBIs, eight walks (3.76%) and 26 strikeouts (12.21%). Of course, his 2017 success was taken with a grain of salt because Rivera was more than two years older than league average.

Rivera emerged as a true prospect in 2018 with Kannapolis, after slashing .346/.395/.502 in 237 at-bats with 15 doubles, two triples, six homers, 24 RBIs, seven stolen bases, six walks (2.26%) and 48 strikeouts (18.11%). After earning a promotion to Winston-Salem on July 21, Rivera held his own in 225 at-bats by slashing .280/325/.458 with 15 doubles, two triples, seven homers, 37 RBIs, 10 homers, seven walks (2.81%) and 44 strikeouts (17.67%). Thus, though his average dipped a bit in Winston-Salem, Rivera improved his power while marginally improving his walks and whiffs.

Rivera shot up the prospect charts last year and now ranks 28th among Sox prospects according to MLB Pipeline. He’s given 50 grades in all categories except power, which earns a fairly low grade of 40. Rivera is an average defensive shortstop who committed 19 errors last year. I project Rivera to begin the 2019 season with the Birmingham Barons; how he’ll do in that difficult hitting environment will determine whether he’s best suited for a starting or utility role going forward.

Jordan Stephens

Right-handed starting pitcher
Age 26
2018 SSS poll ranking 18
2018 High Level Charlotte (AAA)
Overall 2018 stats 8-10 ▪️ 28 starts ▪️ 146 23 IP ▪️ 4.23 ERA ▪️ 139 K ▪️ 54 BB ▪️ 1.398 WHIP

Stephens, a native of Alvin, Texas, played college ball for the nearby Rice Owls. He was considered by many scouts at the time of his junior season to be a possible third-round pick. However, three starts into that season, Stephens was injured and required Tommy John surgery, missing the remainder of the season. Thus, Stephens returned to Rice for his senior season and pitched surprisingly well: 3.17 ERA and 1.14 WHIP over 59 2⁄3 innings, allowing just 51 hits and 17 walks (2.56 BB/9) while striking out 75 (11.31 K/9). Due to his competitiveness and the results he posted during his four-year stint with Rice, Stephens was selected in the fifth round of the 2015 MLB draft — ultimately receiving a signing bonus of $300,000.

Stephens’ results had been solid from 2015-17, moving through the White Sox system quite rapidly while striking out more than one batter per inning and maintaining solid peripheral numbers in the process. He missed the first two months of 2017 with forearm tendinitis but still pitched effectively, with a 3.14 ERA and 1.30 WHIP over 91 2⁄3 innings, allowing 84 hits (.249 OBA) and 35 walks (3.44 BB/9) while striking out 83 (8.15 K/9).

In 2018, after a return to Birmingham for seven blistering starts, Stephens was promoted to Charlotte, where he struggled a bit. For the Knights in 21 starts (107 innings), Stephens posted a 4.71 ERA and 1.46 WHIP — allowing 114 hits (.271 OBA) and 42 walks (3.53 BB/9) while striking out 99 (8.33 K/9). Lefties hit .296 against his offerings at AAA, while righties hit just .242, and a similar differential occurred with Birmingham as well.

Stephens’ top pitch is an excellent, upper-70s curveball with good depth. While his fastball isn’t overpowering, the low-90s velocity is still effective because of the way he hides and locates it. He also has a cutter and changeup, which still need work due to his lack of results against lefties.

Because of issues Stephens has had staying healthy both in the college and professional levels, and due to his relatively small size and bulldog mentality, a switch to the bullpen may eventually be in order. At this moment, unless the White Sox acquire additional starters via trade or free agency, Stephens will be competing against the likes of Dylan Covey, Manny Banuelos, Spencer Adams and Jordan Guerrero in spring training for back-end spots in the rotation. The fact that the White Sox chose to add him to the 40-man roster this month, over the likes of both Adams and Guerrero, indicates he has the inside track on a rotation spot in 2019.
