LEXINGTON, Ky. — Cuban pitching prospect Aroldis Chapman struggled with his command and took the loss in his second minor league start for the Louisville Bats, the Cincinnati Reds’ Triple-A affiliate.

The hard-throwing left-hander gave up one run on one hit and walked four in five innings in a 3-1 loss Saturday to Columbus, the Cleveland Indians’ Triple-A affiliate.

Columbus touched Chapman for a run in the first when two walks led to a sacrifice fly, the first earned run he had allowed this season. He settled down over the final four innings.

Chapman struck out only one despite having five pitches top 100 mph.

In his first start against Toledo on April 11, the 6-foot-4 Chapman struck out nine in 4 2-3 innings. He allowed five hits, an unearned run and walked one.
