LOS ANGELES — Dodger Stadium was probably never louder this season.

But the already deafening roar of the capacity crowd turned into something that pierced eardrums the moment Manny Ramirez drove the only pitch thrown to him last night and sent it screaming into the section of seats named in his honor.

Grand slam.

The four runs Ramirez drove in with that single stroke in his pinch-hit at-bat broke a sixth-inning tie and sent the Los Angeles Dodgers on their way to a 6-2, sweep-sealing victory over the Cincinnati Reds.

The home run off reliever Nick Masset, the first long ball ever hit by a Dodger on his bobblehead night, turned the ballpark into a madhouse.

Fans lured to Chavez Ravine by the promotional Ramirez dolls held the boxes containing their prized toys high above their heads. Some of the patrons pointed to the heavens. Others violently tugged at their replica No. 99 jerseys.

"Kind of crazy," said Ramirez, who wasn't expected to play because he was struck by a pitch in his left hand the previous night.

Then Ramirez came out for a curtain call.

More noise, more madness.

"I guess Manny's (injured) hand wasn't as bad as we thought," Reds manager Dusty Baker said.

The pinch-hit home run was the first of Ramirez's 17-year career. The grand slam was his 21st, ranking him second all-time behind Lou Gehrig with 23.
