Monasterios, whom the Mets selected in December's Rule 5 Draft and then traded to L.A., is 1-0 with a 1.91 ERA. He has made only one start this year, going four innings on May 1 against the Pirates in a game the Dodgers won, 5-1. He gets the call over Ramon Ortiz, who has made two starts, lasting a total of 7 1/3 innings while allowing eight runs.
By placing reliever George Sherrill on the 15-day disabled list, the Dodgers have 11 pitchers for the first time this year, and the club is expected to add a reliever by Friday. Torre said Monasterios would pitch Friday to give Hiroki Kuroda an extra day of rest.
In other pitching news, Vicente Padilla is making a steady recovery from an irritated radial nerve. He threw breaking balls on flat ground Tuesday for the first time and is scheduled to throw a simulated game Saturday in Denver, with Andre Ethier among the batters. If that goes well, Padilla is likely to head out for a Minor League rehab assignment.
Charlie Haeger made his third Minor League rehab start for Class A Inland Empire on Monday night. He allowed two runs in six innings and made 94 pitches, but Torre said he also aggravated the plantar fasciitis that put him on the disabled list. Nonetheless, he is scheduled to start at Inland Empire on Saturday, Torre said.
