ARLINGTON, Texas -- Justin Grimm came into Tuesday's game against Seattle having earned wins in his last two starts.
That number was a tad misleading though because Grimm was the beneficiary of solid offensive nights that masked five-inning starts from the rookie right-hander.
There was no masking his performance against the Mariners.
Grimm was blasted for six runs in four-plus innings as the Mariners opened a three-game series with a 9-2 thumping of the Rangers.
Raul Ibanez and Kendrys Morales set the tone for Grimm in the first inning as each of them ripped solo homers to right. By the time he was pulled after Morales hit his second homer off a Grimm changeup in the fifth, he had allowed seven hits and walked two.
"I left some pitches up and they got a hold of them unfortunately," Grimm said. "I didn't execute pitches. I didn't do my job."
Grimm, the American League rookie of the month in April, was decent in May and has gone downhill since then. His ERA since a June 4 star...
