ATLANTA: The Indians gave up on their $7 million experiment with 32-year-old right-hander Brett Myers Thursday, reinstating him to the 60-man roster and releasing him.

Myers went 0-3 with an 8.02 ERA in 21? innings. Myers gave up 29 hits and 10 home runs during his short time on the mound. That made him one of three players in major-league history to allow at least 10 home runs in a season in 22 innings or less, joining Mike Lincoln (2000) and Joel Bennett (1999).

He has been on the disabled list since April 20 with inflammation in his right elbow.

In seven games in the minors at Double-A Akron and Rookie League Mahoning Valley, he compiled a 3.09 ERA in 11? innings.

“To his credit he plugged away,” Indians manager Terry Francona said. “He could have shut it down multiple times. He was getting antsy because he felt like he was getting ready to help us. Because he’d had such a long layoff we wanted to see him pitch some more. Out of respect to him, [General Manager] Chris [Antonetti] gave him a chance to be let go now before September so maybe he could find a spot in the big leagues.”

CALL-UPS COMING — Francona said the Indians plan two waves of September call-ups. The first will come Sunday, with Francona expecting three pitchers, a catcher and an infielder to arrive. The second group — perhaps all pitchers — will be Wednesday or Thursday.

“We’re going to have a lot of pitchers,” Francona said. “We talked over a lot about what we want to do about Danny [Salazar] pitching and [Corey] Kluber possibly pitching. I think we thought it may be our best way to win.”

BAT MASTERSON — Starting pitcher Justin Masterson singled over the third baseman’s head Wednesday night, and it wasn’t necessarily a surprise. He said during his sophomore year at Bethel College, an NAIA school in Mishawaka, Indiana, he was the designated hitter when he didn’t pitch. That changed when he transferred to San Diego State.

He did little to prepare for this opportunity.

“I took couple dry hacks a couple days ago and a couple off the tee. It’s not like he’s going to try to get nasty on me,” Masterson said of Braves starter Paul Maholm.

COOLING OFF — Francona and pitcher Scott Kazmir took liquid nitrogen treatments designed to improve circulation at a facility near their Buckhead hotel. Francona said it was so cold that when he was told he had a minute left, “I was about ready to say uncle.”
