At 40 years young, A's right-hander Bartolo Colon is proving that things can get better with age.
With a 12-3 record and a 2.70 ERA, he matched the most victories by an A's pitcher before the All-Star break since 1991 and became the oldest All-Star in club history.
Colon has also tossed six or more innings and allowed three runs or fewer in each of his last 12 starts, which is the second longest such streak in Oakland history. During that span, he is 9-1 with a 1.79 ERA.
In his final start before the break against the Red Sox, the right-hander allowed two runs on eight hits in 6 1/3 innings for the no-decision.
"This is the best first half I've ever had in my career," Colon said after the game.
He'll look to keep up that pace in Sunday's series finale against the Angels and right-hander Jerome Williams as the Halos go for the three-game sweep in Anaheim.
Williams is hoping that the All-Star break will get him back on track after hitting a rough patch the first few weeks of July.
In all three starts this month, the right-hander has recorded no more than 10 outs and given up a total of 18 runs. Last Friday against the Mariners, Williams allowed six runs on seven hits in 31/3 innings for his fifth loss of the season.
"Out of the 17 hitters he faced, he must have been in hitting counts with almost all of them," Angels manager Mike Scioscia said. "It was tough. He pitched behind in the count far too many times for what you want to see him do, and he paid a price for it."
Williams believes it comes down to him being more aggressive.
"I'm not controlling the counts," Williams said. "That's basically it. I have to be in the zone instead of trying to get that perfect pitch on the first pitch."
A's: Cespedes out with sore left wrist
Chevrolet Home Run Derby champ Yoenis Cespedes will likely miss his third straight start on Sunday because of left wrist soreness.
Manager Bob Melvin said the left fielder is available to pinch-run and reiterated that the injury has nothing to do with his participation in the Derby.
"If you watched [the Home Run Derby], it didn't look like it was bothering him," Melvin said. "Usually those types of things happen on one particular swing, and it certainly didn't."
Angels: Field recalled
The Halos designated infielder Brendan Harris for assignment on Saturday and recalled infielder Tommy Field from Triple-A Salt Lake.
"Tommy gives us a little more versatility off the bench and it's something that we want to look at," Scioscia said. "I think Brendan, on the offensive side, has struggled in that role, not getting a lot of at-bats and hopefully Tommy will come in and be able to do some things."
Field's natural position is shortstop, but the 26-year-old can play second and third and has even played in the outfield.
In 65 games, Field is hitting .297 with 38 RBIs for Salt Lake. In July, Field had hit .367.
• The A's have scored three runs or fewer in each of the last eight games and have four shutouts over that span.
• The Angels are 11-2 this season when Josh Hamilton hits a home run and have gone 13-0 in his last 13 games with an RBI.
