The Jays picked up a couple players off of waivers from the Reds according to a press release on TSN. In a related move the Jays outright DeJong, Gronkiewicz, and Vermiliyea to Syracuse.
Thanks to Brian W for the heads up.
Gosling (minors) has been a starter in AAA for several years now with a few stints in the bullpen of the Diamondbacks and Reds. The lefty's numbers seem to have improved over recently, although he had a high walk rate and unusually high hit rate with the Reds this season.
Lopez (minors) is a middle infielder who has spent a majority of the time at shortstop. He hasn't had a lot of success at the plate, but did have a hot streak at AAA Louisville hitting .339/.396/.427 this season. In his 2007 Prospect Book John Sickels wrote that most people viewed him as a future utility infielder with his range being his best asset.
