ARLINGTON -- Michael Aubrey's first taste of the big leagues is over, and now Tom Mastny is back for more.
The Indians sent Aubrey back to Triple-A Buffalo on Monday to make room for the right-handed Mastny, who was promoted from the Bisons to round out the Cleveland bullpen. The Indians had been carrying an extra position player.
"We want to be at full strength in the bullpen," said manager Eric Wedge, whose club is in the midst of playing 17 games in as many days.
Mastny was in the 'pen from April 14 through May 11, but he only made two appearances in that span, allowing two runs in 1 2/3 innings. He was optioned back to Buffalo so that he could get regular work.
His second stint with the Bisons this season was a successful one. Mastny allowed just one earned run over his last nine innings of work, striking out eight and walking two.
"He was stringing 'em together pretty good," Wedge said. "He was commanding his fastball and working his secondary stuff off of that."
Aubrey was promoted May 17 and was only expected to be with the club for a few days. But he made an immediate first impression by hitting a home run in each of his first two starts, and he began to grab some at-bats against right-handers from first baseman Ryan Garko.
In nine games, Aubrey hit just .185 (5-for-27).
"It will be good to get Aubrey out and playing," Wedge said. "He got a little look here. Now, he can go out and play every day. I'm sure he'll be back at some point in time."
