LOS ANGELES -- One day after announcing that right-hander Ambiorix Burgos would be shut down indefinitely at Triple-A New Orleans, the Mets took the next step and placed the right-hander on the 15-day disabled list because of elbow soreness.

"There's something wrong with his elbow. It's just inflamed," manager Willie Randolph said, adding that he hopes Tommy John elbow reconstruction surgery will not be needed.

Burgos, 23, acquired from Kansas City, where he appeared in 127 games over two seasons, was 1-0 with a 3.42 ERA in 17 games this season for the Mets. He was optioned to Triple-A when Guillermo Mota was activated.

Martinez throws again: Pedro Martinez continued his rehabilitation Tuesday by throwing "about 50 pitches" in a bullpen session at the team's Port St. Lucie, Fla., facility, according to Randolph. Martinez, who also threw five days ago, pitched both on and off the mound as he continues to test his surgically repaired right shoulder.

"I don't think he's [throwing] any breaking balls," Randolph said. "He's getting a feel for the field and for the mound again. He's just getting his arm loose, basically."

The Mets did not respond to a question about how many bullpen sessions Martinez would require before the club would feel comfortable enough to send him out on a Minor League rehabilitation assignment.

Gomez fine after tumble: Rookie Carlos Gomez said he came out fine after crashing hard at the base of Dodger Stadium's left-field wall in pursuit of a James Loney double Monday night. Gomez, who was back in the lineup Tuesday night, said he had some stiffness in his shoulder, but didn't anticipate it affecting his swing.

Gomez, pressed into everyday service with Moises Alou on the disabled list for the foreseeable future, said he has benefited from the veteran players in the Mets clubhouse.

"A lot of veterans have been teaching me how we play in the big leagues," Gomez said. "There's a big difference from the Minor Leagues. My first week here, I was a little confused. I didn't know how to do things. I watched [Carlos] Beltran. He plays the same position as me. I watched what he does on the field and off the field."

Gomez, who has been with the Mets since May 13, has four RBIs in his last two games. He's held down left field, albeit without much power. Randolph believes the Mets miss Alou's veteran presence, but Gomez said the other experienced players have helped him ease into the role.

"When I feel confused," he said, "I have a guy to put his hand on my shoulder and say, 'The next day, you move on.'

"They tell me that 'everybody, when they're young, did this or that, too. When I was young I did this.' You have to learn. You learn this year for next year. Next year you have more confidence and do whatever you want."

Extras: The Mets signed nine of their 42 picks from the First-Year Player Draft, among them second-round pick Scott Moviel and fourth-round pick Richard Lucas.
