The dominance continues even in spring training. That aside, both Joe Torre and Stan Conte said after the game that groin injuries to pitchers are ALWAYS a concern, especially since this one is to Billingsley’s push-off leg. The next step is a series of muscle tests that will take place tomorrow to see how he responds. Stan said it’s often more about how the pitcher feels the next day than how he feels when the injury occurs. Loretta said he hurt himself making a lunging play on a forceout in the bottom of the fifth inning. Said if it were the regular season, he would have stayed in the game. … Dodgers had nine hits today, ALL of them singles. … Brian Mazone pitched the eighth inning and stranded a runner on third. He now has pitched 6 1/3 scoreless innings, spread over eight appearances, this spring. He also is a left-hander. And the Dodgers NEED a left-handed reliever. But this guy probably will begin the season at abq. … Dodgers fall to 13-12.
