LOS ANGELES -- On Sept. 1, major league active roster limits expand from 25 to 40 players, allowing teams to bring up players from the minor leagues to bolster their team, or in some cases develop young talent for the future, in the season's final month. But don't expect relief pitcher Jose Dominguez to get the call from the Dodgers this season.

The right-hander is still rehabbing at the Dodgers' facility at Camelback Ranch in Glendale, Ariz., on the minor league disabled list with right shoulder inflammation. Dominguez last pitched on July 25, with Triple-A Albuquerque.

"He's been in Arizona for a little bit," manager Don Mattingly said on Saturday night. "At this moment he's not on our radar."

Dominguez, 23, made the Dodgers Opening Day roster in Australia and in four stints with the big club in 2014 allowed eight runs on seven hits in 6⅓ innings, with eight strikeouts and three walks. From the beginning of 2013, among all pitchers with at least 10 major league innings, the 98.0-mph average fastball of Dominguez ranks fourth in baseball.

In 31 games in Triple-A Albuquerque this season, Dominguez was 1-2 with a 3.24 ERA and 10 saves in 33⅓ innings, with 39 strikeouts and 18 walks.
