White Sox No. 2 prospect Michael Kopech deservedly has garnered a lot of attention as he navigates his first season at Double-A Birmingham, but teammate Jordan Guerrero is showing there’s more than one pitcher worth watching in the Barons’ rotation.
Guerrero, a 23-year-old left-hander, was named the Sox’s minor-league pitcher of the month for June after he went 4-0 with a 1.23 ERA, four walks, 26 strikeouts, a shutout and a .195 opponents’ average over five starts. Guerrero has allowed two or fewer runs in each of his last six starts, throwing at least six innings in five of them.
A 15th-round pick in 2012, Guerrero is making strides in his second season at Birmingham and owns a 3.51 ERA over his first 15 starts this year. His 100 strikeouts lead the Southern League, for which he was named an All-Star and the pitcher of the week earlier this month.
Kopech, who was selected to play in the Futures Game during All-Star weekend with fellow Sox prospects Yoan Moncada and Zack Collins, watched his ERA jump to 3.72 after he gave up four earned runs on five hits with three walks and three strikeouts over three innings in his last start.
Micker Adolfo, RF, Class-A Kannapolis: Adolfo earned his second straight player of the month honor after hitting .267 with eight doubles, eight home runs, 20 RBIs and 20 runs over 26 games in June. He had a 19-game on-base streak from June 6-26.
Yoan Moncada, 2B, Triple-A Charlotte: Moncada had hits in his last four games through Saturday, including his ninth double and 10th homer of the year Wednesday.
Reynaldo Lopez, RHP, Triple-A Charlotte: Amid a rough stretch for the Charlotte rotation that has bumped Carson Fulmer’s ERA to 5.31 and Lucas Giolito’s to 5.40, Lopez turned in a strong outing Thursday. He gave up one earned run on six hits with one walk and 11 strikeouts in 6 2/3 innings against Columbus and has a 4.22 ERA.
Danny Hayes, 1B, Triple-A Charlotte: Hayes will play in the International League All-Star Game as Charlotte’s replacement for Nicky Delmonico, who has shoulder inflammation, and Moncada, who will play in the Futures Game. Hayes is hitting .237 with 15 homers and 49 RBIs.
Alec Hansen, RHP, Class-A Winston-Salem: Hansen has given up one earned run on eight hits with three walks and 10 strikeouts over 10 innings in his first two starts since being promoted from Kannapolis.
