White Sox Minor League Update: May 31-June 6

With May in the books, here's a quick rundown of players who made notable strides over the last month:

Charlotte

Chris Beck: Earned a first MLB start with four good starts that resulted in a great line: 3-1, 1.73 ERA, 26 IP, 21 H, 1 HR, 7 BB, 19 K

Junior Guerra: Continues to be "interesting" due to strikeouts, although the walks are a little high: 0-3, 3.33 ERA, 27 IP, 20 H, 1 HR, 15 BB, 37 K

Jason Coats: First full month of Triple-A action was a success: .294/.325/.422 with five doubles, three homers over 109 at-bats. He still needs to refine the strike zone (five walks, 22 strikeouts).

Birmingham

Tim Anderson: .303/.325/.418 over 122 at-bats and 8-for-10 on the basepaths in May. He drew four walks, which raised his season total to ... five. On the plus side, he's committed just nine errors over 48 games. He had committed 24 over his first 48 last year.

Jacob May: Gained control of the zone, hitting. 300/.361/.325 with 12 walks to 15 strikeouts over 120 at-bats. He's running hot-and-cold in the running game (18-for-26 in May).

Courtney Hawkins: Cut his strikeout rate from 37 percent in April to 28 percent in May, while hitting .269/.350/.389 over 125 plate appearances.

Winston-Salem

Trey Michalczewski: The extra-base power showed up, as he hit .265/.352/.513 with nine doubles, two triples and five homers over 128 plate appearances. His batting eye is healthy for his age (20 strikeout rate, 10 percent walk rate).

Kannapolis

Jordan Guerrero: May was worse in terms of ERA (1.80, up from 0.69), but he struck out 30 over 25 innings, and he's working on a 20-inning scoreless streak.

Spencer Adams: Steadying after a rocky April: 1-1, 2.74 ERA, 23 IP, 21 H, 0 HR, 3 BB, 14 K

Sunday's box scores will appear below shortly. Larry's Dominican Summer League preview will run later this morning.
