A year ago, right-hander Garrett Mock started the season in the Nationals' rotation, with the team taking another chance on his considerable talent despite a rough spring. But Mock lasted just one start before going on the disabled list with a neck injury, and this spring, he fared so poorly he didn't factor seriously in the competition to make the Nationals' rotation.
Mock's struggles have continued early this season at Triple-A Syracuse, and against the Pawtucket Red Sox today, he's perhaps hit his low point.
The 27-year-old walked seven batters, four with the bases loaded, and gave up eight runs in two innings in this morning's game at Pawtucket. He has now walked 14 batters in his last 5 2/3 innings for the Chiefs, and has a 7.15 ERA for the year.
The Nationals have continued to give Mock chances because of his stuff; he throws four pitches, including two good breaking balls, and his fastball can touch the mid-90s. But he's consistently struggled in the majors after impressing in the minors, and he's now in his final year with a minor league option. It's possible Mock could be hurt, but if not, it seems like the Nationals might have to make a decision on the right-hander somewhat soon.
