ANAHEIM -- After a dismal four-game stretch for Joel Pineiro, Angels manager Mike Scioscia announced on Thursday that the right-hander would be moved out of the rotation and into the bullpen.

In his last four starts, Pineiro went 0-3 with a 14.85 ERA. He also gave up a total of 22 earned runs and 29 hits in 13 1/3 innings.

With his start on Wednesday acting as the final straw, Pineiro gave up seven runs on seven hits in just 4 1/3 innings.

"It is easy to see the results, and see he is pitching behind and the action on his pitches aren't as crisp," Scioscia said. "The real challenge is to find out why that is happening. Mike Butcher and Joel are trying to do that."

Understanding the challenge of going from a starting role to a bullpen role, Scioscia said the sinkerballer may have to throw some during and after games to get work in and stay fresh.

"You will take that step back and exhale, that's for sure. As far as getting the functional work in, it will be hit or miss," Scioscia said. "Bottom line, where J.P. is right now and where we need him to be, that divide was widening. We need him to take a step back and, hopefully, move forward with it."

Pineiro's move to the bullpen leaves an open spot in the Angels' rotation, however Scioscia wouldn't elaborate on who will take the position. A possible candidate could be reliever Hisanori Takahashi, who was a starter in Japan for 10 years and made 12 starts for the Mets last season.

With an off-day on Monday, Scioscia wouldn't need a fifth starter until Saturday against the Blue Jays. However, that may change, depending on Jered Weaver's appeal of his six-game suspension and whether he is available.

"We are going to need a fifth starter next week," Scioscia said. "There are a number of scenarios we will work through, and [they will] be contingent on where Weaver's suspension falls in."

Scioscia bats Callaspo second

ANAHEIM -- While Mike Scioscia has stayed away from using Alberto Callaspo in the two-hole all season, the Angels' manager penciled him into that very spot on Thursday against the Twins.

"Alberto is a guy that we want to put in an RBI situation, and I think that he has been very comfortable hitting five or six," Scioscia said. "But if you also look at the way he has been setting the table and getting on base, he brings another element that can help us."

The sixth player to be in the role this season, Callaspo has been consistent at the plate the last month. He's was hitting .344 (32-for-93) in his last 29 games heading into action on Thursday.

While the two-hole has been Torii Hunter's spot for the majority of the last two months, Scioscia said he'll likely be keeping Hunter in the three-hole for the time being.

"We'll most likely have Torii hit in three-hole, and work around that and try to get a little more situational look at the front of the order," said Scioscia.

Scioscia also placed Howard Kendrick in the five-hole, after an off-day on Wednesday, and Mark Trumbo in the six-spot.

Callaspo went 0-for-3, with a walk and a run scored in Thursday's game.

Worth noting

• Ron Jackson threw out the honorary first pitch on Thursday at Angel Stadium as part of the team's 81 alumni first pitches during the 50th anniversary season. "Papa Jack" had two different stints with the Angels, spanning seven seasons.

• Trumbo leads the team in home runs (20) and RBIs (58), the first rookie to do so in Angels history.

• The Halos are the only team in the American League West with winning records at home (29-24) and on the road (31-27) heading into play on Wednesday.

• Bobby Abreu is one run shy of 1,400 runs scored.
