Mike Piazza hit a two-run homer to move into a tie with Johnny Bench on the career home-run list, and Carlos Beltran also connected yesterday night in the Mets’ 7-3 victory over the San Diego Padres.

Tom Glavine (7-7) won his third consecutive decision with six solid innings as the Mets won their second straight over the NL West leaders and moved two games over .500 (48-46) for the first time since June 11, when they were 32-30.

Piazza has enjoyed a mini-emergence from his hitting woes since being dropped to sixth in the order for the first time since May 1993 on Tuesday night. He had an RBI double in the third inning to go with his homer off Woody Williams (5-6) in the fifth and is 4-for-7 in the two games. He went 2-for-4 on Tuesday.

Piazza’s homer into the left-field bleachers was his 389th, tying him with Bench, the former Cincinnati Reds catcher, for 46th all-time, one behind Graig Nettles. It was Piazza’s 367th as a catcher, the most ever for the position.

Beltran gave the Mets a 2-0 lead in the first with his 11th homer – second this season when a starter other than Pedro Martinez was on the mound.

Glavine (6-7) was the beneficiary this time and he made the lead stand up, pitching neatly into the fourth inning, where he temporarily lost his rhythm.

After getting seven ground ball outs and a strikeout through three innings, Glavine missed on the corners and worked deep into counts in the fourth inning as the Padres scored twice to make it 4-2 on Xavier Nady’s RBI single and Ramon Hernandez’s sacrifice fly, both with the bases loaded.

Glavine allowed two runs and six hits in six innings and now has given up three runs or fewer in his last five starts. The win was the 269th of his Hall of Fame career.

Jose Reyes doubled in a run in the second with a liner down the left-field line, and the Mets appeared to have scored a second run on a balk call by home plate umpire Chuck Meriwether. But Padres manager Bruce Bochy protested and Meriwether conferred with third base umpire Tim Timmons and reversed it.

Reyes, already in the Mets dugout, had to retrieve his helmet and return to third base. Mike Cameron then struck out to end the inning.

The Mets went up 4-0 in the third on Piazza’s RBI double over the head of center fielder Nady after David Wright singled.

Nady had trouble again in the fifth when he waved off right fielder Brian Giles on Cameron’s fly, only to see it go over his head. Cameron got a triple and scored on Cliff Floyd’s single before Piazza homered to make it 7-2.

Williams allowed seven runs and 10 hits in six innings. He struck out four without walking a batter.
