Brian McTaggart is tweeting that Jed Lowrie is on his way to Corpus to make a rehab start(s).
Seeing that the Hooks are in Frisco for G2 of their playoff series, if he's heading to Corpus, he'll play in G3 tomorrow night.
This isn't unprecedented. The Yankees sent Andy Pettitte to Double-A Trenton to make a rehab start in the playoffs back in September 2010.
