The Dodgers outrighted right-handers John Ely and Carlos Monasterios to Triple-A Albuquerque on Friday, clearing room on the 40-man roster for five players now protected from the Dec. 8 Rule 5 Draft.
The Dodgers added left-hander Michael Antonini, outfielder Alex Castellanos and right-handers Stephen Fife, Josh Wall and Chris Withrow.
Ely appeared in five Major League games in 2011, pitching 12 2/3 innings with a 4.26 ERA. In five innings of September relief work, the 25-year-old allowed no runs on three hits and two walks while striking out four. He went 4-10 with a 5.49 ERA in 18 big league starts in 2010.
Monasterios was injured for most of last season after pitching 88 1/3 innings for the Dodgers in 2010, putting together a 3-5 record and a 4.38 ERA. He made only one start for Albuquerque in '11, pitching four innings.
The 25-year-old Castellanos was acquired from the Cardinals for Rafael Furcal at the Trade Deadline and put up impressive numbers in Double-A this year. Fife, 25, came from Boston as part of the Trayvon Robinson trade.
Antonini, 26, was traded to the Dodgers last year and went 10-9 with a 4.01 ERA and 131 strikeouts in 148 innings for Double-A Chattanooga. The 24-year-old Wall, a second-round pick in 2004, had 57 strikeouts in 68 2/3 innings of relief this year.
Withrow, 22, was the Dodgers' first-round pick in 2007. He posted a 4.20 ERA and recorded 130 strikeouts in 128 2/3 innings for Chattanooga this year.
