Jose Reyes, just 20 years old and with less than a month’s worth of major league baseball under his belt, was in a slump at the plate and a funk in the field. His batting average was plummeting and he’d made huge errors that had helped cost the Mets their previous two games.

One could hardly blame Florida for intentionally walking Tsuyoshi Shinjo to pitch to Reyes last night with the bases loaded and one out in the sixth inning, and one could hardly blame the rookie if he’d been pressing when the Marlins did it.

But what he delivered was the latest in what is already becoming a long line of seminal moments in his dramatic splash on the big-league scene. Reyes laced Mark Redman’s fastball back up the middle for a two-RBI single, the deciding runs in the Mets’ 6-3 win over Florida.

In all, Reyes went 2-for-4 with three RBIs, and made several nice plays in the field – including a dazzling double-play in the fourth – to help the Mets snap a four-game losing streak.

“Reyes came through with three big RBIs for us,” Art Howe said. “Someone asked me if I thought he was pressing. No. He just comes to play. I don’t even know if he knows what pressing means. He just goes out there and has fun playing the game, enjoys being out there.”

He probably didn’t enjoy Sunday, when his 11th-inning error helped send the Mets to a 7-3 loss to the Yanks, or Tuesday, when he booted Pudge Rodriguez’ potential double-play ball for a two-run error in an 8-4 loss to Florida.

“I feel like the same guy, win or lose. It’s part of the game. What can I say? That happened. It happens a lot of times. It’s part of the game,” Reyes said. “I don’t worry about that. I just say, ‘The next ground ball is going to you: Make a play.’ I don’t worry about it.”

So he put it out of his mind, flaring an RBI single into center in the second inning yesterday. And with the score knotted at 3-3 in the sixth, Florida intentionally walked Shinjo to get to Reyes, who came into the night in a 1-for-15 slide.

Reyes fought of Redman’s 0-1 heat middle-in, smacking it back up the middle to give the Mets a 5-3 lead that proved enough. And he had those highlight double-plays on Redman in the fourth (turning it despite getting hit in the left leg by Miguel Cabrera) and Mike Lowell in the fifth.

Vance Wilson praised Reyes as a team player: “It’s not the Reyes show, it’s the New York Mets show. He did the job for the Mets and that’s what’s awesome.”
