Until recently, Bobby Witt and Ruben Sierra were just painful reminders to Oakland fans that slugger Jose Canseco was hitting howitzers for somebody else.

On Aug. 31, Canseco went southeast in a blockbuster trade while the Athletics simply went south.Witt, outfielder Sierra and reliever Jeff Russell arrived from Texas and Oakland, the American League-West front-runner, promptly lost six straight games.

What a difference two weeks make.

Sierra singled home two runs Wednesday night and Witt won his first game for Oakland, helping the first-place Athletics to a 4-2 triumph over the Minnesota Twins and a sweep of their three-game series.

The Athletics' ninth straight victory put them nine games ahead of the second-place Twins in the AL West, reducing Oakland's magic number to eight. Minnesota is the defending World Series champion.

"I don't know what people here expected of me, but I just wanted to pitch a few games here," said Witt, who picked up his first decision with Oakland in three attempts. "Right before I came here, the feeling (of confidence) wasn't there. The feeling that I have right now is that my confidence is back."

Witt broke a personal six-game losing streak and improved to 10-13. He gave up two runs on six hits and three walks while striking out eight over six innings for his first victory since July 25. Russell completed the Texas trifecta by pitching the final 12/3 innings for his 30th save.

"After the first game, deep down inside, I wanted to do so well to show them (Oakland) it wasn't a bad trade," Witt said. "It's getting a little bit more comfortable now."

Witt remembers a time not long ago when things were very uncomfortable for him and Sierra.

"Opening day (in Texas) (Manager Bobby) Valentine, Ruben and myself were booed," recalled Witt. "Now all three are gone. Now I hope I can make these fans happy."

Twins starter John Smiley, 14-9, took the loss.
