CINCINNATI – Joe Randa provided an encore to his dramatic opening-day homer, hitting a bases-loaded single and a grand slam last night that powered the Reds to a 9-5 win over the Mets.

Randa, who won the opener with a ninth-inning solo shot, got the Reds going with a two-run single in the first off Tom Glavine. He got the fans chanting his name after his second career grand slam in the eighth off Mike DeJean, a shot off the batter’s eye in center field.

The third baseman from Kansas City joked before the game that no one recognized him when he went out in public after he hit the first walk-off homer in Reds’ opening day history Monday.

They know him now. The 22,301 fans demanded a curtain call and chanted his name after his slam.

Ken Griffey Jr. also singled off Glavine with the bases loaded, one of his three hits.

The Reds won the first two games of the series by getting past three-time Cy Young winner Pedro Martinez and two-time winner Glavine – a feat the Mets certainly didn’t expect.

First-year manager Willie Randolph had a large cigar waiting on his desk before the game, a gift from Mike Piazza in anticipation of his first win. Randolph picked it up and briefly stuck it between his lips without lighting up.

“I’m going to use it tonight for sure,” Randolph said, laying it back on his desk. “Hopefully I’ll light it up later. That would be nice.”

Again, no cigar.

Glavine is 25-12 against the Reds, his second-highest victory total against any team. Control problems and two borderline calls led to a rare Cincinnati meltdown – five runs in only 3 2/3 innings.

The left-hander threw 37 pitches in the first inning, helping the Reds load the bases with two outs. He got ahead of Randa 0-2 in the count, then jerked his head in disappointment when plate umpire Chuck Meriwether called the next pitch just off the inside corner.

Given a reprieve, Randa singled to left on the next pitch for a 2-0 lead.

The Reds loaded the bases with two outs again in the fourth. Glavine went 0-2 on Griffey, then threw a pitch that Meriwether decided was just outside. Again, Glavine dropped his head in disappointment. And once again, he gave up a hit on the next pitch. Griffey singled to right for two more runs, and Sean Casey singled up the middle for a 5-2 lead. Randa’s slam drew a curtain call and polished it off.

Doug Mientkiewicz and David Wright homered off Eric Milton, who got the win for Cincinnati.
