The link takes you to a McCalvy tweet about Periard. Here's the one about McKelvie. Periard is a former top pitching prospect and was a member of the 40 man roster at one point, but was limited to 15 games last season due to injury and hadn't played in 2011. McKelvie is only 20 but had hit .192/.265/.289 in two seasons for the AZL Brewers. He was a 25th round pick in 2009.
