"Depth is important this time of year, and that's what these guys will give us," Scioscia said of catcher Ryan Budde and right-handed pitchers Dustin Moseley and Darren O'Day after they were summoned from Triple-A Salt Lake with the Sept. 1 roster expansions.
Moseley, a versatile contributor in long relief and as a spot starter last season, will be ready to jump in and pitch multiple innings if necessary. O'Day, one of the early surprises this season with solid work out of the bullpen, will bring his side-armed delivery to middle relief. Budde, who was exposed to big-game pressure with the Angels last season, will give Scioscia support for Mike Napoli and Jeff Mathis behind the plate.
"Dustin has really struggled with some things this year," Scioscia said of Moseley, the 26-year-old right-hander, who underwent surgery last October to relieve pressure on the ulna nerve in his pitching arm. "I don't know if it's related to the offseason surgery he had or not, but he's come a long way.
"We saw him pitch just before the All-Star break as a spot starter for Joe [Saunders], and that was some of the best stuff and aggressive [attitude] we've seen from him. If we see that here, he can contribute. We won't hesitate to use him."
Moseley is 1-3 with a 7.15 ERA in eight appearances, six as a starter, with the Angels this season. He was 7-10 with a 6.94 ERA in 20 starts at Salt Lake.
O'Day, in 27 appearances covering 37 1/3 innings with the Angels, has a 4.34 ERA and is 0-1. A brilliant spring earned the 25-year-old Floridian a spot on the Opening Day roster after just 29 appearances as high as the Double-A level with Arkansas.
"Darren showed some flashes of being able to come in and do the job in a Major League bullpen" this season, Scioscia said. "At times he's really struggled. There's been some growth and adjustments, things he's starting to work on. Hopefully, he'll get in a groove."
O'Day thoroughly enjoyed playing for the Angels' Triple-A powerhouse at Salt Lake, going 2-2 with a 3.27 ERA in 21 games, striking out 30 in 33 innings.
"That was awesome," O'Day said of his Pacific Coast League experience. "It's a fun team to be on, a good atmosphere. But it's great to be back up here, naturally. This is where every player wants to be.
"I needed to work on a couple of things, and I think I did that. Mainly, it's just the consistency I need to keep me here."
Budde, 29, was hitless in six appearances, one as a starter, with the Angels this season after appearing in 18 games last year. He got the call over Bobby Wilson, Salt Lake's No. 1 receiver, in part because of his familiarity with the Angels' pitching staff and also because Scioscia felt Wilson would benefit from postseason experience with the Bees.
"Ryan has done a nice job for us," Scioscia said, "and it'll be good for Bobby, playing in the playoffs."
