Left-handed reliever Brent Leach will miss a couple more days of throwing off the mound because of a sore groin muscle, manager Joe Torre said. Leach, who felt tightness Sunday when the grounds were wet from rain, has been able to play catch on flat ground. Leach was called up from Double-A Chattanooga May 2 and appeared in 38 games for the Dodgers last year with a 5.75 ERA. He had a 2.95 ERA in his first 31 games, 31.50 in his last seven games. He was sent to Triple-A July 30 and struggled the rest of the year to a 6.75 ERA in Albuquerque. — Ken Gurnick
