Athletic ability doesn’t often fall too far from the tree.

In Tommy Sommer’s case, his father Juergen was a goalkeeper for the Indiana University and part of their 1988 national championship team; he played for more than a decade in the professional ranks, ultimately concluding his career in 2004 with the New England Revolution. His mother was no slouch athletically, either, as she was a star high school softball player.

Sommer, a native of Carmel, Ind., pitched four years for his father’s alma mater. Primarily a starter in his first two years, as a junior he started four games and did quite well with a 2.61 ERA and 1.07 WHIP until the pandemic concluded the 2020 season prematurely.

He picked a bad time to have his worst season, but Sommer did just that in 2021. In 12 starts for the Hoosiers totaling 62 2⁄3 innings, he posted a 4.60 ERA and 1.48 WHIP by relinquishing 55 hits (.237 OBA) and 38 walks while fanning 69. His 5.5 BB/9 was more than two walks per game worse than his previous high of 3.4 set in his junior year, but he also reached his career high in K/9 at 9.9.

As a four-year senior who lacked leverage, the White Sox drafted Sommer in the 10th round and signed him to a $20,000 bonus — $123,600 under slot value. Because he had already pitched the most innings of his career while with Indiana, Sommer was kept to a tight pitch count during his pro debut in 2021 with the ACL Sox. Against competition about a year younger than he, Sommer performed exceptionally well by producing a 2.16 ERA and 0.80 WHIP in his eight outings (six) starts. In 25 innings, Sommer surrendered a measly 13 hits (.149 OBA) and seven walks (2.5 BB/9) while striking out 33 (11.9 K/9). Review of these results, however, suggest some future regression, as Sommer’s FIP was 4.23 and his ground ball rate was just 30.2%.

The left-handed pitcher who turned 24 in September had a great 2022 from an ERA perspective. Sommer had a 2.75 ERA in 75 1⁄3 innings in Low-A Kannapolis and a 2.64 ERA in 47 2⁄3 innings in High-A Winston-Salem. Batted ball luck was on his side, however, as opposing hitters’ BABIP was .289 in Low-A and .220 in High-A. As expected, his FIP (3.90 in Low-A, 4.14 in High-A) was much higher than his ERA.

Sommer will likely never be a flamethrower, as 92 mph is his fastball speed limit. Sommer exhibited decent control, averaging 3.00 BB/9 innings last year while striking out 9.44 per nine. Going forward, Sommer will need to keep the ball on the ground as much as possible. His ground ball rate in High-A dropped to 36.1%, and since he is not a power pitcher, he could be especially vulnerable to regression to the mean if that does not rise.

Sommer’s ratins are ALL well better than average:

Command will continue to be key for Sommer going forward, without a big-muscle fastball. As is necessary for someone with a heater that isn’t quite so hot, Sommer also features a complement of secondary offerings to keep hitters off-balance. His cutter cuts away from lefties but moves in on righties, which limits the quality of contact. His best offering is his changeup, which is often used as a put-away pitch. Finally, his fourth offering is a rudimentary curveball that is simply a show-me offering at this point.

Expect Sommer to begin the season with Winston-Salem, but an immediate assignment to Birmingham is not out of the question.
