Parra's left calf feeling much better

ARLINGTON -- Before Wednesday's game vs. the Rangers was rained out, Gerardo Parra was slated to be in the D-backs' lineup after leaving the second game of Monday's doubleheader against the Rangers with a left calf cramp. Martin Prado, who fouled a pitch off the inside of his left knee in the first game of that doubleheader, was not in the lineup but is expected to start Thursday.

"[Prado]'s improved, but we'll give him another day to move around a little bit," manager Kirk Gibson said. "He'll be ready to go tomorrow. He's certainly available tonight."

Prado stayed in the game despite hurting his knee in the fifth inning and went 1-for-4 and pinch-hit, but didn't start, during the second game of the doubleheader. Parra left the nightcap in the fourth inning after getting the cramp when he struck out in the third. He led off and started in right field Wednesday.

"It's a big bruise. The range of motion [in the knee] is kind of stiff, but that's all," Prado said. "Just one more day of rest and getting out all the blood accumulated there. I'm fine. I can run. I can hit. They just want to make sure I'm 100 percent."
