Reds pitcher Kevin Gregg struggles in debut Monday

Reds pitcher Kevin Gregg didn't produce the debut he was hoping for Monday against the Pirates. Gregg came on in relief on starter Johnny Cueto and surrendered a two-run home run to center fielder Andrew McCutchen.

"If you go back and look at the location of the pitch, you'll see it wasn't located that bad. They were obviously jumping on my stuff early," Gregg said to MLB.com.

Manager Bryan Price was hoping for better from the non-roster invitee to spring training.

"I'm always surprised because you don't anticipate guys going in there and scuffling, but it's part of the game," Price said. "We're trying to define our bullpen [roles] as best as possible. The only way to do that is for these guys to go out and pitch."
