CHICAGO: Indians pitching coach Mickey Callaway was given a heads-up about the possibility that Trevor Bauer might pitch from the stretch whether there were men on base or not.

However, Bauer had not rehearsed the change in his delivery at Columbus. The first time he tried it was Friday night, when he started against the White Sox.

“Trevor has his own thoughts on things,” said Tribe manager Terry Francona about Bauer’s decision to initiate a change in his new delivery without trying it out in the minor leagues. “Mickey told me, ‘Don’t be surprised if he pitches out of the stretch.’ Trevor felt really bad for the way he taxed the bullpen. He was kind of sheepish, and I felt bad for him.”

Bauer didn’t get out of the first inning, giving up five runs and retiring two batters. He has returned to Columbus, which was the original plan and had nothing to do with the way he performed.

BULLPEN MOVE — Because relievers pitched 9? innings and threw a 212 pitches in Friday’s doubleheader, reinforcements were summoned from Columbus.

Joe Martinez, ordinarily a starter, joined the team Saturday in case the club needed a reliever to throw three or four innings.

“I don’t know how long he’ll be here,” Francona said, “but he can give us some length.”

The Clippers were playing in Norfolk, Va., and Martinez left to catch his plane at 6 a.m.

“I’d rather be here with no sleep than in Triple-A with plenty of sleep,” Martinez said.

In 15 starts with the Clippers, Martinez, 30, was 2-6 with a 6.23 ERA. He has pitched in 10 major-league games (six starts) with the Giants, Pirates and Diamondbacks.

TOUGH LOVE — Matt Langwell pitched one inning in the second game of Friday’s doubleheader and was sent back to Triple-A, but not because he gave up two runs.

“This is not an indictment on him giving up runs,” Francona said. “I told him that he’d probably be on that shuttle a few times. That doesn’t mean he’s not a good pitcher; it’s probably the other way around. This gives us flexibility.”

The shuttle took Langwell back to Columbus to await his next call-up. So far, he has pitched in five Tribe games.

HOW TIRED? — Francona was surprised to learn Friday’s seven-hour, 53-minute doubleheader set the major-league record for nine-inning doubleheaders.

“I was shocked to read that,” he said.

Asked how he felt Saturday morning, Francona said, “When you usually wake up feeling lousy, it doesn’t feel that much different form normal.”

Or as Jason Kipnis said, “After two games like that, you’re dehydrated, you’re tired, guys’ eyes are glazing over. But I feel better going to bed being 2-0.”

FARM FACTS — Chun Chen and Matt Carson each homered, Chen driving in one run and Carson three, as Columbus fell to Norfolk 8-4.
