Rienzo using extra time to work on adjustments

CHICAGO -- Andre Rienzo was scheduled to start Wednesday's contest against the Tigers, but because of Tuesday's postponement, the right-hander was skipped and moved to Sunday, with John Danks staying on his regular turn.

"It just makes sense," said White Sox manager Robin Ventura of the rotation adjustment. "We had Chris [Sale] that was going [Thursday] anyway. Give [Rienzo] some time. He might be tired. I think it just makes sense to skip him and get him in over the weekend."

Rienzo started the season at Triple-A Charlotte and then won four of his first six starts with the White Sox and made three quality starts during that stretch. But Rienzo has struggled since, losing three straight and giving up 12 earned runs over his last 12 innings.

This down time has allowed Rienzo to put in extra work with pitching coach Don Cooper. He understands location down in the zone becomes crucial for a pitcher who doesn't have overpowering stuff, but he also is focusing on his release point.

"I made mistakes the last two games, and I paid for that," Rienzo said. "They are making me work a little bit with Cooper and [White Sox bullpen coach Bobby Thigpen], so we can make the mistakes not happen anymore.

"It's minimal, but I need to find it again. This timing is good to find it."

Despite the rough stretch, the White Sox stand behind Rienzo as a starter.

"I'm glad they're so confident in me," Rienzo said. "I had pretty good games the first four games, and now I have a little bit of shake. But I like the confidence shown in me, and I want to answer that with good games."
