OAKLAND -- Jarrett Parker blasted three home runs, punctuated by a tiebreaking grand slam in the eighth inning, to power the Giants past the A's with a 14-10 victory on Saturday afternoon at the Coliseum.
"It's the best offensive game I've ever seen, personally," Giants manager Bruce Bochy said. "To hit a grand slam with the game tied, just an amazing day for this kid."
Zito, who made his first start in the big leagues since 2013, exited after two-plus innings, allowing four runs on six hits and a walk.
Hudson started off strong, throwing a scoreless, eight-pitch first inning, but he unraveled in the second when he struggled to find the strike zone. Major League Baseball's active wins leader completed 1 1/3 innings, giving up three runs (two earned) on one hit and three walks. He also hit a batter to allow a run in his final outing at the Coliseum.
"I lost the feel for the strike zone," Hudson said. "I couldn't really find it for whatever reason."
MOMENTS THAT MATTERED Parker's power surge: Parker became the first Giants rookie since Brandon Belt in 2011 to hit two home runs in a game. He is the first Giant to homer three times in a game since Pablo Sandoval in 2013 and the first rookie to pull off the trifecta in the Majors since Andrew McCutchen in 2009. Parker has six home runs in 18 at-bats since being recalled on Sept. 11. More >
"I've been trying to help the team out any way I can," Parker said. "Hitting that home run, putting us ahead was a great feeling. That's what I've been trying to do since I got called up."
Adding on: Though their record isn't indicative of their resilient ways, the A's showed off this trait several times Saturday, keeping at it with the bats. After Hudson and Co. generously gave them three runs in the second inning, four doubles -- from Stephen Vogt, Eric Sogard, Billy Burns and Mark Canha -- helped them get five more in the third. Billy Butler's two-run homer in the sixth, his second in as many days, provided some insurance runs that ultimately weren't enough.
Multiple miscues: The wheels fell off for Hudson when Matt Duffy's error loaded the bases in the second inning. Hudson then walked in two runs and hit Canha with a pitch to allow another man to cross home plate. In the third, Parker had trouble finding Canha's fly ball in left, which dropped in front of the San Francisco left fielder to extend Oakland's lead to four.
"They all feel bad when they make a mistake and they do want to make it up," Bochy said. "[Parker] felt horrible about it. It's nice to see a player not just concerned about his hitting."
"In this game, you have some very difficult, hard decisions. I'm going to tell you, that was right there for me. He was just so out of sync. I didn't know if his hip was bothering him and he wasn't saying anything, but I've never seen him that much out of sync. He might have been caught up in the moment. I'm sure today was a really emotional day for him, but I just felt at that point, I had to protect him. It was the last thing I wanted to do in that situation because it was his day, but I just felt like he needed help." -- Bochy, on having to pull Hudson in the second inning
REPLAY REVIEW Brett Lawrie hit a chopper to Duffy, who picked up the ball and fired to first in the fourth inning. First-base umpire Jim Wolf initially ruled Lawrie beat the throw, but after review, the call was overturned and Lawrie was ruled out.
WHAT'S NEXT Giants: San Francisco turns to right-hander Chris Heston (11-10, 3.51 ERA) to finish up its final road trip of the season in the series finale of the Bay Bridge Series on Sunday at 1:05 p.m. PT. Heston is coming off an outing against the Padres in which he lasted just 4 1/3 innings. He did not give up a run on two hits and five walks in the no-decision.
Athletics: Left-hander Sean Nolin, who is 1-1 with a 4.57 ERA in four starts since his promotion from Triple-A Nashville, will take the mound in Sunday's finale against the Giants.
