ARLINGTON -- With Derek Holland making his first start since being placed on the disabled list June 7, Justin Grimm was optioned to Double-A Frisco on Saturday.
Grimm went 1-1 with a 10.80 ERA in three outings during his first big league stint. He will start in Frisco on Monday before moving up to Triple-A Round Rock, whose All-Star break ends Thursday. Holland, who had been experiencing a stomach virus and shoulder fatigue, was activated Saturday after going 0-2 with a 6.00 ERA in two Minor League starts with Round Rock.
"He didn't get shaken by a whole lot," manager Ron Washington said of Grimm. "I thought that was important."
The 23-year-old right-hander beat the Astros on June 16 in his Major League debut, giving up three runs on six hits in six innings. Grimm also became the first American League pitcher in 47 years to strike out seven without a walk in his first big league start. He took his first big league loss when he gave up six runs in one inning during a loss to Detroit on June 25.
"I learned a lot," Grimm said. "I started out strong in the debut. Things didn't go my way in Detroit. I would've liked to get another opportunity there. I just have to keep going and keep learning and keep getting after it."
