After being moved from the starting rotation to the bullpen recently, Bautista was sent to Omaha on Thursday as Kyle Snyder came up to start against the Rangers.
"The reason we did Bautista was because he wasn't going to get the kind of innings he needed working out of the bullpen," Royals manager Buddy Bell said. "We still want to get him in the rotation at some point. Hopefully, he'll straighten himself out."
Bautista was 0-2 with a 5.66 ERA in 35 innings. He made seven starts before the Royals sent him to the bullpen. In his lone relief appearance on Tuesday, he worked three innings and allowed two runs on three hits. Ian Kinsler delivered a two-run homer during Bautista's relief stint.
"It's just about being able to repeat his delivery," Bell said. "Certain situations dictate whether he can stay in his mechanics. We're hoping that he can understand the situation, slow down and stay in his delivery."
Greinke's outing: Right-hander Zack Greinke had another encouraging rehab outing on Wednesday for Double-A Wichita. Greinke allowed three runs in six innings against Springfield while striking out five. Greinke gave up four hits and a homer in a 5-3 Wichita win.
"It was pretty good, better than the previous [outing]," Bell said. "He was 88 to 95 [mph] and used all of his pitches. They hit a homer off him and he kind of got out of his delivery for a hitter or two. But he was able to regain it."
The Royals are proceeding cautiously with Greinke. Bell said the club doesn't want what's going on at the Major League level to dictate when Greinke will make his 2006 Royals debut.
Meeting with Moore: After a couple of telephone conversations earlier, Bell had a chance on Thursday to sit down face-to-face with new general manager Dayton Moore.
Bell's primary message was that there are a number of players on the Kansas City roster that the manager believes in, although Bell noted they must continue to improve.
"It's a tough situation for him to get into right now in the middle of the season," Bell said. "I came in the middle of the season last year and that was tough enough. I can't imagine what he has to go through in terms of putting an organization together."
Clinic set: Some Royals coaches and players will host a free instructional clinic for youth from Smithville Baseball on Friday.
The participants, who have been pre-selected by their youth league, will receive one-on-one instruction in fielding, batting and pitching during the 90-minute clinic from outfielder Shane Costa, pitcher Andrew Sisco and coaches Fred Kendall and Brian Poldberg.
The clinic will be held from 11:30 a.m. to 1 p.m. at Smiths Fork Park.
Gordon sidelined: Top Royals' prospect Alex Gordon, the third baseman at Double-A Wichita, didn't play on Thursday after getting three stitches in his left foot following an injury at home.
The Wichita Eagle reported that Gordon was taking out the trash when he stepped on a bottle and cut his foot. Manager Frank White said Gordon could miss one to five games.
Coming up: The Royals will open a three-game series against the Tampa Bay Devil Rays on Friday with LHP Mark Redman (1-4, 6.80) taking on LHP Mark Hendrickson (3-6, 4.01) at 7:10 p.m. CT.
