Maroth, who won a career-high 11 games last year after losing 21 in 2003, has been reached for 16 runs over 15 2-3 innings in dropping his last three outings. The 6-foot left-hander was pounded for six runs and nine hits over 4 2-3 innings in Tuesday’s 8-2 home loss to Texas.
“I used all of my pitches. I threw a lot of strikes,” Maroth said. “But they were not good strikes. They were up and over the plate. They’re too good a team to do that to.”
Maroth has struggled mightily at Comerica Park this year, going 1-4 with a 7.16 ERA in six home starts. Opponents are batting .338 against him in Detroit.
