Renteria pleased with revised replay system

SAN FRANCISCO -- So far, the new replay review system seems to be working, Cubs manager Rick Renteria said.

"I feel we've gotten more calls corrected that might not otherwise have been corrected," Renteria said Wednesday. "I still think [replay] alleviates the umpires from so much scrutiny. They want to get the call right. They're human beings, they make mistakes, but they're doing their best.

"You've got to give them credit -- it's not the easiest job in the world to be an umpire."

Renteria would know. He's been ejected three times this season and was the first manager to get tossed in the regular season.

"The guys who I have a difference of opinion with were pretty patient with me," he said. "I thought they were very professional. They give me 15, 20, 30 seconds to say what we need to say. At least in my case, they've allowed me time to say what I say."
