Mock to make spot start Saturday

Right-hander to be called up from Triple-A Columbus

MINNEAPOLIS -- Nationals right-hander Garrett Mock, who is currently in Triple-A Columbus, will pitch against the Rangers on Saturday night. The team has not announced a corresponding move.

The last time Mock pitched in the big leagues was on June 8 against the Giants. It was his Major League debut and it was an outing he would like to forget. He didn't get past the fifth inning as the Nationals lost to the Giants, 6-3, at Nationals Park.

The team hopes this next outing is a different story.

"He'll come over here and he will not have the nervousness of the first start. Hopefully, he will feel more at home and give us a solid outing," manager Manny Acta said.

Mock is replacing left-hander Odalis Perez, who is on the disabled list because of tendinitis in his left shoulder.
