The Nationals spent five years hoping Garrett Mock would blossom into a front-line pitcher and gave the right-hander plenty of chances to realize his potential, both as a starter and a reliever.
But Mock's results never matched his arsenal and left him toiling away in the minors this season. And now, he's no longer a member of the organization.
Mock has signed a minor-league contract with the Blue Jays, offering a new opportunity to resurrect his career.
The 28-year-old was first acquired by the Nationals, along with lefty Matt Chico, in the 2006 trade that sent Livan Hernandez to the Diamondbacks. The Nats touted him as a potential front-line starter, and he got his first chance to pitch in the majors in 2007 in both the rotation and bullpen with mixed results (1-3, 4.17 ERA in 26 games, three of them starts).
Mock got even more opportunity to pitch in 2008, making 15 starts and 28 overall appearances. But he finished an abysmal 3-10 with a 5.62 ERA.
Despite all that, Mock entered spring training in 2010 all but assured of a rotation spot. He did making the Opening Day roster, but after lasting only 3 1/3 innings in his season debut, he was optioned to Class AAA Syracuse. He later revealed he had a sore neck, an injury that ultimately required surgery.
Mock spent all of this season in the minors, going a combined 1-5 with a 6.39 ERA in 26 games at Syracuse, Harrisburg, Potomac and the Gulf Coast League.
