Chapman gave up an earned run on one hit and a wild pitch in one-third of an inning in Saturday's 4-1 loss to the Mariners. He also recorded a strikeout.
The new Cubs closer couldn't hold a 1-0 lead in the eighth after relieving Hector Rondon. Chapman came on with two out and runners at the corners and promptly gave up a two-RBI double to Leonys Martin. After Martin subsequently stole third, he scored on the fireballing reliever's wild pitch. The 28-year-old had been perfect over the 2.1 innings spanning his first pair of appearances for Chicago while recording four strikeouts, and Saturday's earned run was the first he'd given up since June 27 with the Yankees.
