He's been on a roll for a while now, but even to his manager, C.J. Wilson was a "notch above" Saturday night.

For the first time all season, Wilson pitched into the ninth inning, giving up no runs and only three hits, but was still aware of the slippery slope in his profession.

"Comfort's like a four-letter word in baseball," Wilson said after the Angels' 2-0 victory over Oakland at Angel Stadium. "You get too comfortable, and guys start whacking you all over the place. So you have to stay adamant and stay vigilant, I think that's what it is.

"It's like workplace safety - if there hasn't been an incident in 99 days, then you're looking to extend that streak and that's kind of the way it is."

With some defensive help from third baseman Alberto Callaspo and left fielder J.B. Shuck, Wilson (10-6) won his sixth game in his last seven starts. He was so effective, he was receiving a standing ovation from the crowd before Manager Mike Scioscia arrived to the mound to replace him in the ninth inning.

"It was command," Scioscia said. "His ball-strike ration was incredible up to about pitch 90. He had pitches he was getting ahead with, pitches he was putting guys away with, didn't have to get back into too many counts. Today, he was a notch above."

Josh Hamilton drove in a first-inning run with a sacrifice fly and Callaspo homered to lead off the seventh as the Angels recorded their seventh shutout of the year and shut down the A's for the second straight night following Jered Weaver's performance Friday.
