Meek, an NL All-Star in 2010, was sent to Indianapolis on May 1 with a 5.59 ERA in nine games with Pittsburgh. He allowed just two hits in six scoreless innings at Indianapolis.
Meek's addition gives Pittsburgh eight relievers.
Now Presley will go to Indianapolis, mired in a 3-for-42 slump over his last 15 games. He's batting .220 with 2 homers and six RBIs this season.
Says manager Clint Hurdle: "His game hasn't been in place."
