LAA@CLE: De La Rosa picks up save in Angels' 5-2 win

ANAHEIM -- Angels manager Mike Scioscia was understandably pleased with his bullpen after it turned in four scoreless innings during Saturday night's 6-5 victory over the Astros.

However, it is impossible to ignore the workload that has been placed on the relief corps this season.

"A couple guys are exhausted, let's just say it," Scioscia said. "Many guys are throwing too much, so you have to make decisions on giving guys days off, which has further thinned some of the depth you have down there."

The Angels bullpen has thrown 377 1/3 innings this season -- sixth in the American League. Dane De La Rosa, who had pitched in just 12 Major League games prior to this season, leads the unit with 56 appearances.

Scioscia declined to name any relievers who might be overworked, but said they are "absolutely" monitoring De La Rosa's workload and that the right-hander is "holding up."

"There are some guys, first of all, trying to find roles in the big leagues, define them and then having those roles stretched because of lack of performance or guys struggling or guys out," Scioscia said. "It's been difficult."

Frieri, De La Rosa sharing closer's role

TOR@LAA: Frieri fans Bonifacio to notch the save

ANAHEIM -- Ernesto Frieri pitched two scoreless innings Saturday and has not allowed a run in his past three outings, but Angels manager Mike Scioscia is not quite ready to say Frieri is the closer again.

"I think you'll see Dane [De La Rosa] get some opportunities and you'll see Ernie get some opportunities," Scioscia said. "We have to be able to get those last three to six outs, and if they're both available, great. If one's down, the other guy is certainly a guy that can fill in."

Frieri has held the closer's role for the majority of the year but lost it during a two-week span in which he appeared in seven games and allowed 12 runs in 4 2/3 innings.

In 51 innings, Frieri has 76 strikeouts with a 4.41 ERA and 26 saves in 30 opportunities.

De La Rosa leads Angels pitchers in appearances with 56 and has a 3.56 ERA with one save in four chances.

"Dane's done a great job for us, Ernie looks like he's back on track," Scioscia said. "That'll impact a lot of things that can happen in the bullpen."
