"I'll remember it as a perfect game through nine," Expos catcher Darrin Fletcher said. "I would have loved to have had him finish that off in the 10th inning. I really wish we would have won the game in the top of the ninth and not have that lineup turn over again for the bottom of the 10th."

The Expos took a 1-0 lead in the top of the 10th on Jeff Treadway's run-scoring single off Brian Williams.

In the bottom of the inning it looked as if Martinez might lose the victory, as well. Rojas threw a wild pitch that allowed Roberts to reach third. After Steve Finley grounded out to first, Tony Gwynn hit a sharp grounder to second baseman Treadway, who threw Roberts out at the plate. The game then ended on Ken Caminiti's foul pop.

The last perfect game in the majors was by Kenny Rogers of Texas against the California Angels on July 28, 1994, a 4-0 victory.

The last perfect game in the National League was by another Expos pitcher -- Dennis Martinez, now of the Cleveland Indians and no relation to Pedro -- on July 28, 1991, a 2-0 victory at Los Angeles.

Last year, Martinez had a perfect game through seven and a third innings before hitting Reggie Sanders of Cincinnati. He kept the no-hitter through eight, but lost it on Brian Dorsett's leadoff single in the ninth.

Until Saturday night, Martinez's reputation was based more on his sometimes faulty control. He has caused a number of bench-clearing brawls by pitching inside. He hit a league-high 11 batters in 23 starts last year. Three batters, including Sanders, rushed him, touching off brawls, and the incidents led to a total of 12 ejections.
