Though the Angels were all smiles after Thursday's 8-3 win against the A's, things could change drastically come Friday's contest in Oakland.
That's because Bartolo Colon will be on the hill for the A's. Not only did the right-hander carve up the Halos last season, going 2-1 with a 1.66 ERA in three starts, he dominated them in one start this season.
Facing the Angels on Sunday, Colon had his best outing of the season, tossing a four-hit shutout. He also struck out two and walked five for his 13th victory of the season.
"He just knows how to pitch. He made pitches," Angels outfielder J.B. Shuck said after Sunday's game. "He knew what he needed to do to get outs, located well and made pitches when he had to."
The 40-year-old has tossed six or more innings and allowed three runs or fewer in each of his last 13 starts, which is the second longest such streak by an A's pitcher since at least 1916. He's also 10-1 with a 1.62 ERA during that stretch.
Meanwhile, Angels right-hander Jerome Williams will be out for a little payback after getting roughed up by Oakland in his last start.
He allowed six runs (four earned) on eight hits in five innings of work on Sunday for his sixth loss of the season. Pitching into the fifth inning just once in July, Williams' ERA has ballooned from 3.21 to 4.73.
However, Williams and manager Mike Scioscia felt he had a better rhythm throughout the game, something he had trouble with at the beginning of the month.
"I thought he threw the ball well," Scioscia said after the contest. "If you look at the line score, it doesn't look really healthy, but I thought Jerome threw the ball very well. He had both sides of the plate going, just not a lot of luck."
Angels: Gutierrez ready to help bullpen
After being cut by the Royals on July 14 and then claimed off waivers by the Angels on Wednesday, reliever J.C. Gutierrez is ready to make his mark in the bullpen.
"It was a lot of time gone after I got designated for assignment," Gutierrez said. "I was thinking a lot and talking to my agent. He said, 'Be good, keep working hard and someone will claim you.'"
On Thursday, the Angels guaranteed him a spot in their bullpen, designating right-hander Billy Buckner for assignment in order to create room on the active roster.
They wasted no time using him, having him pitch the ninth inning of Thursday's game, in which he allowed one hit.
A's: Vogt recalled
Oakland placed catcher John Jaso on the seven-day disabled list with a concussion and recalled catcher Stephen Vogt from Triple-A Sacramento on Thursday.
Jaso exited Wednesday's series finale against the Astros in the eighth inning with a headache after he was hit in the mask by a foul tip for the third time in four games.
"Nowadays, there's more evidence and more scrutiny put upon those types of things," A's manager Bob Melvin said. "In the past, you kind of just played through these things and I think it's shown with some injuries, head injuries in the past, that you do need to be more careful with it."
Melvin said he anticipates the seven days will be enough for Jaso to recuperate. He must spend a minimum of seven days on the DL, and he will be transferred to the 15-day DL if he hasn't healed after 14 days.
• Angels starter Jason Vargas (blood clot in left armpit area) is closer to getting in a rehab assignment than Sean Burnett (left elbow impingement), but it's still "going to take a little more work for Jason," Scioscia said. Both continue to throw bullpen sessions.
• The A's have scored 62 runs in 10 games against the Angels this year.
• Colon is 11-6 with a 3.17 ERA in 22 career starts against the Angels.
