Arlington, Texas — Things have been looking grim for Justin Grimm.
He had the worst earned run average of any starter in the majors in June.
July hasn't started out any better.
The Rangers rookie lost to the Mariners Tuesday night at the Ballpark, 9-2.
Grimm gave up two home runs in the top of the first.
He gave up another homer in the fifth.
The Rangers had won their last four series against Oakland, Saint Louis, the New York Yankees and Cincinnati.
But Texas lost the first game of the Rangers' series against Seattle.
