ANAHEIM -- More than anything, Alberto Callaspo is known for his solid defense at the hot corner -- which is why it's so obvious that the switch-hitting third baseman hasn't been right lately.
Callaspo bobbled a slow roller by David DeJesus to lead off the third inning on Tuesday, marking the fourth error he's committed over the last three games -- the previous three of which were errant throws. Over his previous 37 contests, he committed only one error (a dropped fly ball on April 10).
"I feel fine," Callaspo said in Spanish. "That stuff happens. Tomorrow is another day. I just have to keep moving forward."
Lacking best stuff, Weaver keeps club in game
ANAHEIM -- Jered Weaver did not have his best stuff Tuesday night vs. the Cubs, but the right-hander did exactly what aces are expected to do as he battled through it and gave his team a chance to win.
"[Weaver] didn't have his best stuff, and I think he got a little tired as the game went on. He's just really getting back into some of his stamina, but that's what [Weaver] can do," manager Mike Scioscia said after his club's 4-3 win. "When he doesn't have his best stuff, he can keep you in the game like he did tonight. A couple unearned runs and outside of that, he pitched a strong game."
Over six innings of work, Weaver allowed three runs (one earned) on six hits while striking out five.
"Obviously first-pitch strikes weren't quite on today, but I was able to make some pitches when I needed to," Weaver said. "I just tried to keep us in the game, give us a chance to win."
Weaver threw 95 pitches -- 60 for strikes -- and although the right-hander said he felt he could have pitched the seventh inning, he acknowledged he still has some work to do before he is 100 percent again.
"I think it's going to take me a little while to get [my endurance] back, but at the same time, I feel pretty good out there," Weaver said. "Maybe the mechanics aren't quite there, getting a little quick at times trying to get a feel for the game, but for the most part, everything feels good."
In his two starts since being activated from the disabled list, Weaver has struck out 12 and allowed just two earned runs over 12 innings.
Jepsen riding scoreless streak in return from DL
ANAHEIM -- Since returning from the disabled list, Angels reliever Kevin Jepsen has thrown 3 2/3 scoreless innings, allowing just two hits while striking out five.
Jepsen, who was out with a strained triceps, had allowed four runs in 3 2/3 innings of work prior to his injury.
A few days ago, manager Mike Scioscia said he thought Jepsen's velocity has increased, not only from the beginning of the season, but from 2012 as well.
Jepsen simply believes the better numbers are the result of his health and mechanics.
"At the beginning of the year, it was keeping me from getting extended," Jepsen said of his injury. "Now, with no pain, I'm able to get that fastball down and away to a righty. Everything is out front, so I can spin my breaking ball, I can spin my curveball. I'm able to throw all my pitches right now and it feels good. It's relieving to go out there and throw all your pitches."
However, the right-hander does not completely dismiss the notion that his velocity may be a tick higher than it used to be.
"At the beginning of the year, my [velocity] was down with the injury, it was keeping me from throwing the way I need to throw," Jepsen said. "But right now, I don't know what my [velocity] was last year, they probably have a better idea than I do. Maybe I am [throwing harder]."
• Garrett Richards is available in the Angels bullpen on Tuesday. Richards left Sunday's game after rolling his left ankle.
• Left-handed reliever Sean Burnett is close to throwing a bullpen session. Since Burnett has only missed a week, it appears a rehab assignment won't be necessary.
• The Angels had three prospects earn recognition for their May performances. Right-hander Cam Bedrosian, outfielder Zach Borenstein and outfielder Randal Grichuk were named Minor League Pitcher, Player and Defender of the Month, respectively.
Bedrosian, ranked the club's No. 20 prospect, posted a 1.80 ERA with a .193 BAA, Borenstein hit .356 with a 1.085 OPS and Grichuk, who is organization's No. 7 prospect, was credited with 46 putouts and a .980 fielding percentage.
• Peter Bourjos was 1-for-4 with a home run as the designated hitter in his rehab assignment with Class-A Inland Empire on Tuesday. Bourjos is slated to play center field for Inland Empire on Wednesday. Scioscia also wants Bourjos to play with Triple-A Salt Lake before he returns to the Angels.
