Blue Jays edge San Francisco

TORONTO (AP) - Barry Zito didn't expect Edwin Encarnacion to hammer his first-pitch changeup for a home run. Even the Blue Jays third baseman was starting to wonder when he would emerge from his slump.

Encarnacion hit a tiebreaking homer in the eighth inning and drove in three runs as Toronto beat the San Francisco Giants 3-2 Friday night.

Encarnacion homered into the lower deck in left field on Zito's first pitch of the eighth, snapping a 2-all tie.

Zito said Encarnacion connected on a pitch so good, "I'd throw it again."

"It was probably (on the) black but it was (at the) knees, it was down, first pitch, and you're not looking for a guy to do that right there," Zito said.

Encarnacion came in stuck in a 2-for-26 slump and had not homered since June 4.

"I felt great and I said 'About time,'" Encarnacion said after the homer, his ninth. "I've just got to keep going and keep playing hard."

Encarnacion hit a two-run single in the fifth and went 2 for 2 with a walk. Eight of his past 16 hits have been home runs.

"I hope everything is going to come in a bunch now," Encarnacion said. "I need it."

Scott Downs (2-5) worked one inning of relief for the win and Kevin Gregg closed it out in the ninth for his 17th save in 20 chances.

Zito (7-3) allowed three runs and four hits in eight innings for his 11th career complete game and first since May 19, 2009. He walked one and struck out five.

"Z threw great," Giants manager Bruce Bochy said. "That's a tough loss for him because has had good stuff, he gets a complete game, a great effort and we just couldn't get enough runs for him."

Pablo Sandoval drew a bases-loaded walk off Blue Jays right-hander Brandon Morrow to give the Giants a 1-0 lead in the first.
