Cubs prospect RHP Corey Black allowed one run on four hits in six innings Thursday, striking out eight batters for Double-A Tennessee.
He walked two batters in the outing. Black, 22, is in the midst of his best month of the season, as the right-hander has posted a 1.52 ERA and 23-10 strikeout-to-walk ratio in 23 2/3 innings over his last four starts. Overall, Black has pitched to a 2.63 ERA this season to go along with a .203 opponents’ batting average and 91-46 strikeout-to-walk ratio in 89 innings for Tennessee. Though he’s a hard thrower with a swing-and-miss arsenal, the effort in Black’s delivery limits his overall command as a starter and prevents him from working deep into games. He’s more likely to serve as a reliever in the major leagues.
