"Nobody has ever done this," Martinez said.
His doctors -- Mets physician David Altchek performed the surgery -- told him they knew of no other pitcher who had pitched within a year of rotator cuff repair.
"Nobody has been able to climb that big mountain," Martinez said. "I'm happy to give it a try."
It will be a full-effort, partial try. Martinez will be restricted to 75 pitches -- about five innings worth for him -- and no more than 35 in an inning. He said the restrictions will make this start unusual.
"Hopefully, the next one will be normal," said Martinez, who promised the Mets he would abide by the limits, as if he could remain on the mound against the will of Willie Randolph. "I had to agree to that. I know it's for my own good. I gave my word. ... I can't be greedy."
A different 300: Saturday is the 300th day the Mets have spent in first place since the beginning of last season and the 120th day this season.
You can never have enough: The pitching staff increased by three Saturday with the additions of Saturday starter Mike Pelfrey, Philip Humber and left-handed reliever Willie Collazo.
Humber, 24, went 11-9 in 25 starts with the Triple-A New Orleans Zephyrs this season. His 4.27 ERA was the 10th lowest in the Pacific Coast League. He allowed three hits and one earned run in his last 13 1/3 innings. Humber pitched
139 innings, allowing 129 hits and 44 walks while striking out 120. The Mets' first-round selection in the 2004 First-Year Player Draft -- third overall -- appeared in two big league games last season, pitching two innings in relief.
Collazo, 27, never has been on a big league roster. He had a 6-5 record with four saves and a 2.46 ERA with the Zephyrs this season. He pitched 98 2/3 innings in 53 appearances, allowing 91 hits and 19 walks. He struck out 69. He had a 6-2 record and a 1.90 ERA in 49 games in relief after making four starts for New Orleans. His ERA in his 20 most recent appearances (36 1/3 innings) was 0.50.
Furthermore: Kevin Mulvey, the Mets' first selection in the 2006 Draft, has been promoted to the New Orleans roster. Mulvey produced an 11-10 record and a 3.32 ERA in 26 starts and 151 2/3 innings with the Double-A Binghamton Mets. ...

This date in Mets history -- Sept. 2: Reds rookie Pete Rose hit the first pitch of the game from Jay Hook for a home run, the lone run in the Mets' 1-0 loss at the Polo Grounds on this date in 1962.

Former Met Preston Wilson tied the score in the ninth with a homer against Armando Benitez, and Juan Encarnacion won the game with an RBI double against Scott Strickland. The Mets won the second game, 11-5, with Mike Piazza hitting a pinch-hit, three-run home run. The victory ended the longest home losing streak in the National League since 1911.
