PITTSBURGH (AP) _ Wil Cordero went 5-for-5 with four RBIs, and the Pittsburgh Pirates had 20 hits in a 13-9 victory over the New York Mets on Wednesday night.

Pinch-hitter John Vander Wal's two-run double highlighted a five-run seventh inning that carried the Pirates to their sixth win in eight games. Cordero added a two-run double in the eighth.

The Mets, losers of seven of nine, went ahead 7-6 in the top of the seventh against Jose Silva (3-1) when Mike Piazza and Robin Ventura singled and Todd Zeile doubled.

In the bottom of the inning, the first seven batters reached base for the Pirates. Jason Kendall singled off Dennis Cook (3-1), and Brian Giles was hit by a pitch. Kevin Young's single off Pat Mahomes tied the game, and Cordero singled to load the bases.

Pat Meares' single broke the tie, and Vander Wal blooped a double to short left field. Rickey Henderson pulled up a stride short on the ball, which bounced over his head and into the bullpen.

Luis Sojo followed with an RBI single as Mahomes faced five batters and gave up hits to all of them.

Vander Wal is 5-for-11 as a pinch hitter with nine RBIs.

The 20 hits were the most the Mets allowed since giving up 20 to the Pirates on Sept. 26, 1992. The last time the Pirates had 20 or more hits was Aug. 4, 1998.

The Pirates went into the sixth trailing 6-3 against Rick Reed. Young opened the inning with a single, and Cordero homered to the fourth level at Three Rivers Stadium, an estimated 434 feet.

Meares singled, moved up on reliever Turk Wendell's balk and scored the tying run when center fielder Melvin Mora misplayed Adrian Brown's fly ball into a double.

The Mets took a 6-1 lead with five runs in the third against starter Todd Ritchie. Edgardo Alfonzo doubled in two runs, Piazza hit a two-run homer and Ventura followed with his seventh homer.

Young led off the Pirates' second with his fifth homer, tying the score 1-1.

In the fourth, Meares tripled in a run, and Brown tripled and scored when Warren Morris grounded out.

In his first four starts this year, Reed allowed four earned runs in 29 2-3 innings. In his last three, he's given up 15 earned runs in 21 1-3 innings.
