GLENDALE, Ariz. -- Dodgers reliever Javy Guerra was hampered by a strained right groin muscle on Saturday, when he allowed two runs in two-thirds of an inning in a Minor League game against the Reds.
Guerra, who had pitched one-third of an inning in Friday's rainout against the Giants, was halted at a 25-pitch limit on Saturday, having walked two and allowed two hits, including a triple.
Guerra downplayed the injury, calling it "something minor" that cropped up Sunday and led to a mechanical flaw. He said a "simple adjustment" made while throwing in the bullpen after his outing brought pitches that sailed high during the game back into the strike zone.
"When I'm a hair off, it changes everything," said Guerra, who had knee surgery last season and shoulder surgery after the season. "I know my arm is healthy. The biggest thing is that if my arm is 100 percent, I can pitch with anybody."
Guerra has had an eventful week, having been added to Team Mexico for the World Baseball Classic last weekend, only to be dropped before play began because of liability issues following the shoulder surgery.
Guerra, who a year ago was the Dodgers closer, is in a battle to make the Opening Day roster because of the club's bullpen depth and the surplus of starting pitchers that might be relegated to relief.
Also pitching for the Dodgers in the "B" game were Matt Magill (3 IP, 0 R), Stephen Fife (1 IP, 0 R) and Steve Ames (1 IP, 0 R).
