Bob Posey, who tied the game in the seventh inning with a three-run home run, sent a line drive over the left field fence in the 11th to lift Durham to a 7-5 victory over Prince William last night in a Carolina League game before 611 at Davis Ford Park in Woodbridge.

Durham raised its record to 4-4. Prince William, which has yet to win at home in two games, is 2-4.

Paul Assenmacher (2-1) got the win in relief, giving up one earned run in the last five innings. Chip Cunningham (0-1), who entered the game in the 11th, took the loss.

Behind starter Jim Neidlinger, who mixed a slow curve and fast ball to retire 16 straight batters in the middle innings, the Pirates took a 3-0 lead and appeared to be on their way to a quick victory.

But in the seventh, Durham's Mike Yastrzemski led off with a soft liner to left. Chris Baird followed with his second base hit and Posey hit a three-run homer to tie the game.

Prince William came back in the eighth with two runs, keyed by Frank Klopp's RBI triple.

In the ninth, the Pirates' Orlando Lind, who had not allowed a run since relieving Neidlinger in the seventh, walked Chip Childress with two outs and Sal D'Alessandro hit a 2-0 pitch for a homer to send the game into extra innings.

Prince William took a 2-0 lead in the first inning on an RBI single by Dimas Gutierrez and a double by Steve Barnard.

Durham was led by Baird, who went three for five. Gutierrez had three hits in five at bats for the Pirates.
