Double-A rehab start up next for Wilson

ANAHEIM -- C.J. Wilson, nursing a sprained right ankle, will make a rehab start with Double-A Arkansas on Monday.

The 33-year-old Angels left-hander said he threw around 125 pitches in an up-and-down bullpen session (like a simulated game) on Wednesday and around 40 in a bullpen session Friday.

Manager Mike Scioscia did not say if Wilson would need a second rehab start or if he would rejoin the Angels after his outing in Arkansas.

Wilson, who has a 10.26 ERA in his last four starts, is expected to be back by early August.

Hamilton given day off to rest achy knee

ANAHEIM -- Josh Hamilton was out of the Angels' starting lineup Saturday, still nursing a sore left knee after leaving Friday's game early.

Hamilton said his knee felt better Saturday, and manager Mike Scioscia expects him to return to the lineup Sunday.

The 33-year-old left fielder had started 46 consecutive games, although three of his last seven starts had been as the designated hitter.

"It's just spillover from playing a lot and sometimes you just need to take a half-step back and catch your breath a little bit," Scioscia said.

Scioscia said Hamilton wanted to play Saturday but the Angels chose to give him the day off.

"He was laboring to move [Friday], so it was obvious that it had gotten to a level where we want to err on the side of caution," Scioscia said.

Efren Navarro, who replaced Hamilton on Friday, started in left field on Saturday.

Shuck recalled for OF depth; Salas sent down

ANAHEIM -- In a move to deepen their hobbling outfield, the Angels recalled J.B. Shuck from Triple-A on Saturday. Reliever Fernando Salas was optioned to make room on the roster.

The Angels' outfield has thinned due to a recent rash of injuries. Josh Hamilton left Friday's game with a sore knee, Collin Cowgill is on the disabled list with a broken thumb and nose, utility man Grant Green is on the DL with a lumbar strain, Kole Calhoun is fighting a bruise on his knee, and Mike Trout hasn't missed a game since early June.

"On the position player side, we've been thin and some guys definitely need to get off their feet," manager Mike Scioscia said. "The outfield depth is something we need for this weekend."

Salas was simply the victim of a "numbers issue," Scioscia said, as the Angels moved to a seven-man bullpen.

Since returning from the DL on July 6, Salas had a 3.86 ERA in six appearances.

"This move is totally a reaction to some of our outfielders being banged up and needing some depth and really has nothing to do with how Fernando was pitching," Scioscia said.

Shuck played in 19 games with the Angels in April and May, hitting just .173. After a three-hit game against the Mets on April 13, Shuck went 9-for-67 (.134) in his next 16 games.

"When I came up here the first time, I was just trying to do too much, and once I got in a hole, it just snowballed and got worse," Shuck said.

In 74 games at Triple-A Salt Lake, Shuck hit .318 with 42 RBIs.

Worth noting

• With Josh Hamilton out of Saturday's lineup, Erick Aybar assumed Hamilton's vacated cleanup spot. It was Aybar's first career start in the No. 4 hole. His only previous at-bat as a cleanup hitter came as a substitute in 2008.

"If you look at where Erick's really started to have an impact on our club, is letting him get in a position where he can slash with guys in scoring position," manager Mike Scioscia said.

Aybar's 51 RBIs are tops among American League shortstops, and he should shatter his career high of 59 from 2011.

• The Angels signed left-handed pitcher Randy Wolf to a Minor League contract on Saturday and assigned him to Triple-A Salt Lake.

The Angels became the fifth organization Wolf has played for this season, joining the Mariners, D-backs, Marlins and Orioles. The 37-year-old pitched in the Majors this season for the first time since 2012. In six games (four starts) for Miami, Wolf went 1-3 with a 5.26 ERA.
