To illustrate Bartolo Colon's dominance in shutting out the White Sox on Friday night, consider Adam Dunn's at-bats.

Oakland's scouting report on Dunn included a warning: Don't pitch him away. That's exactly what Colon did.

"I gave him something else," said catcher John Jaso, referring to the signs he flashed Colon, "and he kept shaking me off right to that spot. A guy's eyes can light up because that's his pitch to hit. Then it moves off that spot when he's already committed to it. That was pretty impressive.

"That's what he did with everybody. Everything he threw had movement."

The A's beat the White Sox 3-0 before 16,416 at the Coliseum, and Colon registered his first nine-inning shutout since May 30, 2011, when he pitched for the Yankees.

Again, at the Coliseum.

"He could tell me it's coming, and it wouldn't make a difference," said Dunn, who has 418 career homers. "When his ball moves that much and he puts it where he does, I don't care what your hot zone is. You can't do anything with those pitches he threw me. You can't get them in the air. You can't do anything."

According to the A's scouting report, Dunn generates extensive power on pitches away, allowing him to extend his arms and power up. Colon didn't care. Each ball Dunn hit was a two-seamer (sinker) away. Dunn hit three grounders and went 1-for-3. His hit was fielded by third baseman Josh Donaldson, who was shifted toward shortstop and didn't have a play.

"You can't do anything with those pitches," repeated Dunn.

Through seven innings, it was 0-0. Neither team reached on a walk. Neither team reached second base. In the eighth, White Sox starter Dylan Axelrod finally budged. Jaso opened with a double, and Josh Reddick, in his first game since May 6, followed with an RBI double to chase Axelrod.
