Kaz Matsui hit a tiebreaking single with two outs in the eighth inning, and the Mets won their home opener by rallying past the Houston Astros 8-4 yesterday.

Matsui also drove in a run with a bunt single, Tom Glavine threw six solid innings, and Jose Reyes used his speed to send the Mets to their second consecutive victory following an 0-5 start.

Morgan Ensberg had three hits and an RBI for Houston, which had won four in a row after an opening-day loss to St. Louis.

With the Mets trailing 4-3 in the eighth, Victor Diaz drew a one-out walk from Russ Springer and went to third on a single by pinch-hitter Marlon Anderson. Reyes then hit a comebacker to Springer, who made an ill-advised decision to try for an inning-ending double play instead of holding the runner at third. Anderson took out shortstop Adam Everett, and Reyes easily beat the wild throw to first as Diaz scored the tying run.

Reyes stole second on the next pitch and scored on Matsui’s single to center. After an intentional walk to Carlos Beltran, Ramon Castro hit a popup to shallow right and the ball dropped when second baseman Craig Biggio and right fielder Jason Lane collided. Lane was charged with an error, allowing another run to score.

Cliff Floyd followed with a two-run single off ex-Met John Franco, making it 8-4. Roberto Hernandez got the win. He entered with a runner on second and none out in the eighth and prevented further damage.

An RBI double by pinch-hitter Jose Vizcaino off Dae-Sung Koo in the top of the eighth put Houston ahead 4-3. Ensberg started the inning with a double and scored on Lane’s triple off Manny Aybar, tying it at 3. Everett cut the Mets’ lead to 3-2 with an RBI single off Aybar in the seventh. The Mets were coming off their first win of the season, an energizing 6-1 victory Sunday in Atlanta behind Pedro Martinez’s two-hitter and Beltran’s go-ahead homer. And they went up 3-1 in the sixth by scratching out three runs against Andy Pettitte without hitting the ball hard. Diaz tied it with a looping RBI single to right – Lane might have been able to make the play but he first broke back on the ball. Pinch-hitter Miguel Cairo drove in the go-ahead run with a bloop single, and Matsui’s bunt single made it 3-1.

Pettitte heard plenty of boos in his return to New York. The left-hander pitched nine seasons for the Yankees from 1995-03 and helped them win four World Series titles. He allowed three runs and nine hits in 5 1/3 innings.

Glavine was much better than his last start, when he lasted only 3 2/3 innings in Cincinnati. He gave up one run and four hits, striking out six. The left-hander still has not lost to Houston since June 4, 1995, with Atlanta. He has won his last 10 decisions against the Astros.
