Ankiel and left-handed reliever John Parrish will travel to Omaha for a game on Tuesday against Oklahoma City. Ankiel (strained right quad) has been out since May 3. Parrish (left rotator cuff inflammation) has been out since April 24 and will have missed 37 games.
Playing just 19 games, Ankiel was batting .210 (13-for-62) with three homers and nine RBIs.
"He's swinging the bat really well in batting practice, but that's just batting practice," manager Ned Yost said. "I told him it's real important for him to go down and get his timing back because when his timing is right, he crushes the ball to all fields and when his timing's not right, he's a little more susceptible to the offspeed stuff."
Yost wants Ankiel to stay with Omaha long enough to be productive immediately when he returns to Kansas City.
"Mitch Maier has been doing a nice job so it's important for him to go get himself back on track and step in seeing the ball, swinging good and hitting the ball good and be a big asset to us," Yost said.
Maier, in 44 games, had a .252 average with one homer and 21 RBIs.
Parrish will join Dusty Hughes as the only left-handers in the bullpen because Bruce Chen has joined the rotation. Yost noted that Hughes has been more effective against right-handed hitters so Parrish's return will give the Royals more of a lefty specialist.
"When we get Parrish back and have Dusty, you'll have two guys you can bring in from the left side, but Parrish is more of a situational guy, a guy to come in and get a big lefty out in a big situation," Yost said.
