In case you somehow missed it, John Russell told Rob Biertempfel that Kevin Hart is the front-runner for the fifth rotation spot. Hart's got good stuff and I guess he might eventually harness it and turn into a good starter, but I'm not really a fan of hearing this for several reasons.
On the plus side, at least JR emoted a little bit. From the article:
"He's throwing the ball really, really well," Russell said, arching his eyebrows and raising his voice. "So we're very excited."
Arched his eyebrows! Raised his voice!
