(TMZ) - J.J. Watt didn't let a little thing like a broken leg keep him from throwing out the first pitch in a HUGE Game 3 of the World Series in Houston ... and obviously -- the crowd loved it!!!
Watt's a hometown hero for raising more than $37 MILLION for Hurricane Harvey relief ... so you gotta think the fans will give him a pass for the pitch to Astros pitcher Dallas Keuchel being juuuuuuust a bit outside.
J.J.'s season with the Texans is over after having a season-ending surgery a few weeks ago ... but clearly he can still have an impact on the baseball field.
Looks like Watt gave the Astros the extra lift they need. They went on to beat the Dodgers, 5-3. Los Angeles leads in the best of seven series 2-1.
