Castillo (7-3) allowed one run on three hits with six strikeouts and three walks across seven innings while taking a loss against the Cubs on Saturday.
He was outstanding but allowed a second-inning homer to Jason Heyward that was all the Cubs needed. Castillo has been particularly effective In his last six starts, permitting only 10 earned runs in 34 innings. The 26-year-old is 7-3 with a 2.47 ERA and a 1.15 WHIP despite walking 52 in 98.1 innings, though Castillo has offset the free passes by punching out 115. He will be on the mound again at home against the Brewers next Thursday.
