OAKLAND -- Albert Pujols' tight left hamstring was "no worse" on Thursday morning, which Angels manager Mike Scioscia considered a good sign. But there's still no telling how long the veteran first baseman will be out.
Pujols only got treatment Thursday, hours after his hamstring grabbed on him while jogging down the first-base line on a sixth-inning single on Wednesday night. The Angels transition to a National League park in San Francisco for the weekend set, eliminating the designated hitter and potentially ruling Pujols out until Monday, at the earliest.
Pujols said he's feeling "much better" and would try to return to the lineup on Saturday or Sunday, but only if he's certain he won't aggravate the injury.
"I'll be careful," Pujols said. "We'll see how I feel."
Pujols' absence had a pretty sizeable impact on Scioscia's lineup, which was struggling to score runs even while he was in there. Mike Trout settled into the No. 3 spot, Erick Aybar moved from fifth to first, Johnny Giavotella went from ninth to second and Kole Calhoun -- 13-for-32 in his last eight games heading into Thursday's series finale -- moved from leadoff to cleanup.
"Out of all the guys you'd want to hit behind Mike, right now it's Kole," Scioscia said. "… It's a deviation from what we really want to do in our lineup, but I think the circumstances are very clear. Right now, there's a lot of guys trying to find their game. And with Albert out of the lineup, we have to make some adjustments."
• Fernando Salas was initially credited with the win on Wednesday, but the official scorer and Elias Sports Bureau decided Thursday morning to instead give the win to Mike Morin, who retired the final batter in the bottom of the sixth before the Angels took a three-run lead in the top of the seventh. Salas kept the A's scoreless in the bottom of the seventh of the Angels' eventual 6-3 victory.
• Roberto Baldoquin, the 20-year-old Cuban shortstop who was given an $8 million signing bonus this offseason, was placed on the Minor League disabled list a week ago with a strain of his left lat. Baldoquin was batting .154 and had committed six errors in his first 11 games at Class A Inland Empire. He's expected to be out "at least another week," Angels general manager Jerry Dipoto said.
