Three wins against the A's, three different uniforms -- in the same season. What a thing.
Williams pitched the Phillies to a 3-0 victory at Oakland on Saturday, adding to his wins against the A's while with Houston and Texas earlier this year.
The right-hander is the first pitcher since at least 1900 to have at least one win against the same opponent with three different teams in the same season, according to STATS.
"I've been aware of it since I knew I was going to pitch against these guys," Williams said. "That is crazy. For one, you would never think that you would face the same team. Obviously I was with the AL West so I knew I was going to face them, but coming over to the Phillies in interleague play, you didn't think you were going to face the team again. It's a good feat."
No. 9 hitter Galvis reached double digits in RBIs.
"As soon as I hit it, I knew it was a gapper. I tried to run fast. Then I saw it was gone," Galvis said. "You're happy when you put your team in that position."
Williams allowed four hits, struck out three and walked one in seven innings. The right-hander was 0-2 with a 4.08 ERA in his previous three starts. He was aided by double plays in the second and fifth innings.
Oakland lost for the seventh time in 10 games, again failing to support its starting pitcher. The A's squandered a bases-loaded chance in the second when Derek Norris grounded into an inning-ending double play.
"Jerome doesn't really give in, so he's going to give you something over the outer part of the plate," Norris said.
Drew Pomeranz gave the A's all they hoped for from him in a spot start, allowing one hit and walking two in five scoreless innings. Manager Bob Melvin expected him to throw between 75-80 pitches and he finished at 86.
Pomeranz escaped a bases-loaded jam in the first and retired 10 straight batters from there.
The left-hander made his first start since another spot outing Aug. 27 at Houston. Jason Hammel will return to the rotation Thursday when he rejoins the club from his paternity leave.
Ken Giles became only the second Phillies pitcher to earn a save this season, finishing the four-hitter on his 24th birthday for his first career save. Suspended closer Jonathan Papelbon has the other 37.
"It's awesome. I'm going to remember it forever," Giles said. "I've been waiting for my time to come. I'm blessed that I got the opportunity to get it on my birthday."
Philadelphia earned just its third win in eight games at the Coliseum and improved to 2-4 on its final road trip of the year.
Phillies: Oakland native Jimmy Rollins, still recovering from a strained left hamstring that has sidelined him since Sept. 8, expected a few family members in the stands Saturday but the infielder told some there was no pressure to come with him being hurt.
Athletics: CF Coco Crisp had most of the day off until entering as a pinch hitter in the eighth. He had played 14 straight games since missing five with a strained neck. ... RHP Jarrod Parker, who has missed the season following a second Tommy John surgery, will travel to Arizona on Wednesday to continue his throwing program. He hopes to pitch at least twice off the mound this fall before shutting it down in November for the rest of the year. He hopes to be back by next June.
Phillies: RHP A.J. Burnett (8-17, 4.40 ERA) tries to end a two-start losing streak when he makes his first start against the A's since losing with the Yankees on July 23, 2011.
Athletics: LHP Scott Kazmir (14-9, 3.44 ERA) looks to snap an 0-4 skid over his last five starts. He is 14-6 with a 4.31 ERA in 26 interleague starts.
