All good things must come to an end.

And that's exactly what happened to the Yankees' eight-game winning streak Saturday afternoon at Yankee Stadium, as the Oakland Athletics defeated the Yankees 6-4.

The game started out as a pitchers' duel between Andy Pettitte and Gio Gonzalez. Gonzalez, who gave up 11 earned runs in his previous start, took a no-hitter into the fifth inning before a Melky Cabrera bunt single ended that bid. Pettitte also was dealing, as he had a perfect game going until one out in the fourth.

The Yankees got on the board first in the sixth inning when Brett Gardner hit an RBI triple to right center.

But things unraveled for Pettitte and reliever Alfredo Aceves in the top of the seventh inning. Pettitte allowed a leadoff double and a walk. With one out, Rajai Davis hit an RBI single to tie the game. Following that, Bobby Crosby reached on a bunt single to load the bases and knock Pettitte out of the game.

Aceves started out well, as he got Mark Ellis to pop out. However, three straight hits resulted in five more runs for the A's, as they took a 6-1 lead. Aceves had catcher Landon Powell in an 0-2 hole with two outs when the game was 1-1, but his single to left opened the floodgates.

All told, Pettitte was charged with four runs in 6 1/3 innings, striking out seven and allowing five hits. Aceves gave up two earned runs in 1/3 of an inning.

The Yankees went on the comeback trail in the eighth inning. Derek Jeter hit a two-run home run over the right center manual scoreboard to cut Oakland's lead to 6-3. Mark Teixeira followed two batters later with a solo home run just to the left of the right field foul pole. They would try to muster a rally in the ninth - Cabrera and Johnny Damon both walked with no outs - but Jorge Posada grounded into a double play right after to end any hopes of a comeback.

Sergio Mitre goes for the Yankees tomorrow afternoon as they'll look to take three of four against their Oakland foes.
