NEW YORK - Mets first baseman Mike Piazza sprained his left wrist when a baserunner collided with him as he reached for a throw in the second inning of Tuesday night's game against the Florida Marlins.

Third baseman Ty Wigginton threw wide on a bunt by Juan Pierre, and the runner and ball arrived at first base at the same moment. Pierre hit Piazza's left hand as the first baseman reached for the throw. As the ball bounced away, Piazza dropped his glove in obvious pain and clutched his left wrist. Pierre advanced to second on Wigginton's error.

Eric Valent replaced Piazza at first base.

X-rays on Piazza's wrist were negative. He will be re-evaluated today.

PIRATES: Pittsburgh won't be asked to shift any home games to Puerto Rico next season despite the popularity of Hall of Famer Roberto Clemente's former team there, commissioner Bud Selig said Tuesday.

Selig denied that his office would ask the Pirates to play one series in San Juan in 2005 to partly make up for the Montreal Expos' expected absence. The Expos played 22 home games in Puerto Rico each of the last two seasons as they prepare to relocate to a new home.

Any possibility of a Pirates return visit probably ended when the Expos and Pirates drew four-figure crowds for each game of a four-game series July 8-11.

"As far as our experiment with Puerto Rico, it was pretty much done this year, at least for a while," Selig said.

PADRES: San Diego outfielder Darren Bragg opted for free agency after being sent down to Triple-A Portland.

The Padres sent Bragg down after receiving shortstop Rich Aurilia in a trade Monday with Seattle.
