OAKLAND -- For more than three hours, the game between the Phillies and A’s at Oakland Coliseum on Saturday had a little bit of everything: heroic pitching, injury scares and a frustratingly quiet output from a Phillies offense that had been red-hot coming into the game.

In the final 15 minutes, the Phillies added another key element -- aggressiveness. And that ended up being the difference-maker in a 3-2 win over the A’s in 12 innings.

“I've said the word ‘resilient’ about this club over and over for the last two years,” manager Rob Thomson said. “And that's exactly what they are. They just stay after it. They have a lot of fun and want to win.”

Fans of old-fashioned station-to-station, bunt-‘em-over baseball would have enjoyed the final few innings. Each team took advantage of the extra runner on second base in the 11th, scoring a run apiece. The Phillies separated themselves in the 12th thanks to a heady baserunning decision and one very well-placed base hit.

With Cristian Pache starting the inning on second base as the extra runner, Edmundo Sosa lifted a fly ball to center that appeared to be too shallow for Pache to advance. But the speedster took off anyway, diving headfirst into third base and beating Esteury Ruiz’s throw by a hair. Pache overslid the bag, but he got his foot back just ahead of another tag attempt by A’s third baseman Jace Peterson.

“As soon as that ball was hit, I was confident I was going to be safe at third,” Pache said.

Kyle Schwarber, who had been intentionally walked in the 10th, laced a base hit up the middle, pushing home the eventual winning run.

“It's a good win overall,” Schwarber said. “It's easy to lose focus. They're putting pressure on you every time, bunting in extra innings. To be able to stay locked in, do things right, take care of the ball, walk away with the win here -- it's nice.”

The win sealed the Phillies’ fifth straight series win and their 12th victory in 14 games, giving life to the theory that this particular month on the calendar brings out the best in them. Over the past two seasons, the Phillies are 31-12 in June.

The good news wasn’t limited to the final score. Cristopher Sánchez, called up from Triple-A Lehigh Valley to make a spot start, breezed through his first three innings, retiring nine straight. He carved his way through the fourth, too, even after he was hit on his pitching hand by a 102.6 mph comebacker by Ruiz, which initially looked as if it would knock Sánchez out of the game.

As soon as he was hit, Sánchez threw his glove to the ground and walked toward second base, visibly in pain. After a few seconds, he knelt to the ground, and got a visit from a team athletic trainer.

Things didn’t look like they were improving any when Sánchez’s first warmup pitch sailed to the backstop. But his next few pitches hit the target without incident, and he was permitted to finish the inning.

And what a finish it was.

Sánchez walked JJ Bleday but mowed down the next three batters. Ryan Noda looked at a 92.5 mph sinker for strike three. Brent Rooker whiffed on an 80.9 mph changeup, and Jonah Bride swung and missed on the same pitch, ending the inning. A fired-up Sánchez walked off the mound with an emphatic fist-pump.

“In big moments like that, you get that reaction,” a smiling Sánchez said through the team’s interpreter.

Sánchez said he felt his hand swelling up toward the end of his outing, and Thomson opted to remove him then. Precautionary X-rays were negative, and Thomson said Sánchez will start the next time his rotation spot comes up. This is good news for a rotation in need of stability from the fifth starter spot. Entering this game, the Phillies were 2-10 when it’s the fifth starter’s turn to pitch.

Meanwhile, on Saturday, 40 of Sánchez’s 61 pitches went for strikes.

“If that ball didn't go off his hand, he would have gone back out,” Thomson said. “He was fantastic, he really was. Pumping strikes, breaking ball's good, changeup was really good in that last inning and he got some strikeouts with it.

“We got him out on a good note. He goes out with a lot of confidence, and he'll get ready for his next start.”
