Mets C Mike Piazza was placed on the 15-day disabled list yesterday because of inflammation in his left knee, leaving New York without its best hitter as the team tries to stay on the edge of the NL playoff race.

The move was made retroactive to Aug. 7. Piazza had an MRI exam on Tuesday and received a shot in his knee.

The 11-time all-star is batting .276 with 17 homers and 44 RBI this season but has slumped badly since June.
