Worth noting

• Left-hander Sean Burnett will begin a rehab assignment with Double-A Arkansas on Saturday. Burnett, who has thrown in extended spring training, has not appeared in a Major League game since May 2013 after undergoing elbow surgery.

• Right-hander Dane De La Rosa will need to make at least one more rehab outing before rejoining the Angels, pitching coach Mike Butcher said. De La Rosa, who has been limited to one appearance this season due to right s/c joint irritation, could potentially return to the club before the four-game set in Toronto concludes.

Ernesto Frieri will act as the Angels' closer for now, but both he and Joe Smith are likely to get save opportunities moving forward, Butcher said. Smith, who been dealing with tightness in his right side, which forced him to miss Los Angeles' three-game set against the Yankees, has converted three saves this season, the same as Frieri.

It was Frieri's job to start the season, but he struggled and allowed Smith to enter the mix.

"There will be times throughout the year where there will probably be a better matchup with Joe Smith out there," Butcher said.
