OAKLAND, Calif. -- Forty is the new 30 for Oakland A's right-hander Bartolo Colon.
Colon won his second straight start Friday night since turning 40 on May 24, shutting out the Chicago White Sox on five hits in a 3-0 victory.
Colon struck out three and didn't walk a batter for the second straight game.
He outdueled White Sox right-hander Dylan Axelrod, snapping the 27-year-old's three-game winning streak. Axelrod allowed two runs and four hits in seven innings, striking out seven and walking none.
Axelrod shut out the A's for seven innings, but Oakland catcher John Jaso led off the eighth with an opposite-field double to left. Josh Reddick brought him home with a double to right, giving the A's a 1-0 lead.
Reddick, who was activated from the disabled list after missing 22 games with a sprained right wrist, knocked Axelrod out of the game with his double.
Left-handed reliever Matt Thornton took over and walked Brandon Moss, the only batter he faced. Pinch-hitter Adam Rosales advanced the runners with a sacrifice bunt against reliever Jesse Crane before Coco Crisp lined a two-run single to center off Crane, making it 3-0.
Colon and Axelrod matched zeroes for the first five innings, and neither one allowed a base runner past first.
The White Sox had just three hits to that point, all two-out singles.
Chicago third baseman Conor Gillaspie lined a single to center in the second, and Adam Dunn and Jeff Keppinger had infield singles in the fourth. The A's had the shift on for the left-handed hitting Dunn, but he went the other way, hitting a ground ball to the hole and beating third baseman Josh Donaldson's throw. Keppinger beat second baseman Eric Sogard's throw on his single.
The A's had just one hit off Axelrod through the first five innings. Sogard lined a two-out single to right in the third before Axelrod retired Coco Crisp on a comebacker to end the inning.
NOTES: A's catcher Luke Montz was optioned to Triple-A Sacramento, opening a spot on the 25-man roster for Reddick. Montz hit .179 with one home run and five RBIs in 13 games with the A's. ... White Sox second baseman Gordon Beckham (fractured left wrist) resumed his rehab assignment on Thursday night at Triple-A Charlotte after five days off and went 3 for 5 with a double, an RBI and two runs scored against Toledo. On Friday night, he went 1 for 5 with a walk-off single against Rochester. "It's more on his level of pain tolerance really, of going through it," White Sox manager Robin Ventura said. "But baseball stuff, he's ready to go."
