SAN FRANCISCO -- Giants catcher Buster Posey relied on humor to summarize how long Wednesday's 5-4, 13-inning Interleague victory over the Toronto Blue Jays seemed. Asked about Madison Bumgarner, who pitched the first 6 2/3 innings for San Francisco, Posey said, "That was today, wasn't it?"
Ultimately, Posey's eye was as sharp as his wit. He drew a bases-loaded walk to break a 13th-inning tie and enable the Giants to outlast the Blue Jays. By capturing the four-hour, 28-minute standoff, the Giants avoided being swept in the three-game series.
The Giants' clutch-hitting woes continued. They went 2-for-17 with runners in scoring position, moving their five-game total in those situations to 4-for-43 (.093). But Giants manager Bruce Bochy didn't apologize for the lack of authoritative hitting as his club snapped a three-game losing streak.
"It's good to win any way you can at that point," Bochy said. "We'll take the walk."
With the score tied, 4-4, the Giants broke through in the 13th against right-hander Ryan Tepera, Toronto's sixth reliever. After Brandon Belt was nicked by a pitch, Toronto catcher Russell Martin pounced on Denard Span's bunt and made a one-hop throw to second base that was mishandled. Tepera's second pitch to Joe Panik was wild, prompting an intentional walk that set up a force at home. Matt Duffy, who had three hits, sliced a soft liner to first baseman Edwin Encarnacion. Up came Posey, who drew his free pass on four pitches.
Posey said Tepera's pitches missed by the width of "a ball or two inside. Not drastic."
The Giants built a 4-1 lead behind Bumgarner, who allowed three hits before Toronto rallied. The Blue Jays scored twice in the eighth on Martin's sacrifice fly and Justin Smoak's pinch-hit single. That set up Michael Saunders' ninth-inning leadoff homer off Giants closer Santiago Casilla, which tied the score and forced extra innings. Casilla blew his third save chance in 10 opportunities.
"We missed some opportunities but our guys battled to even come back," Blue Jays manager John Gibbons said. "To come back and tie that thing, it was just one of those games, you burn through everybody to get to that point. But, yeah, you never want to lose a game on a walk."
MOMENTS THAT MATTERED
Timely hit:Gregor Blanco entered the game in a 1-for-18 tailspin, but singled sharply to right field on the first pitch he saw from Toronto starter Marcus Stroman. That drove in the first of two runs the Giants scored in the second inning.

Costly errors:Troy Tulowitzki began his Blue Jays career with 59 errorless games but he has made six since April 26, and the two he committed Wednesday afternoon loomed large. In the second, Conor Gillaspie hit a tailor-made double-play ball to Tulowitzki at shortstop. He bobbled the ball and then made a late throw to first base as San Francisco went on to score two in the frame. In the 10th, Tulowitzki made another error with a pair of runners on base. That loaded the bases with one out but reliever Drew Storen escaped the jam to keep the game alive.

"I'm not going to sit here and talk about Tulo not hitting, not fielding or anything like that," Gibbons told a group of reporters. "The guys played a good game out there. They battled."
Saunders goes solo: The Blue Jays were down to their final three outs when Saunders led off the ninth inning with a shot to straightaway center field. According to Statcast™, Saunders' fifth of the year traveled 411 feet and left his bat at 103 mph. It was Saunders' first home run since he went deep twice against the Rays on April 29.
"He ended up leaving a fastball up," Saunders said. "I was trying to stay in the big part of the field and try to stay through it. I fouled some good pitches off; he threw me some good sliders, a curveball that I was fooled on but was able to make contact with it, foul it off, and get a pitch I could handle."
Bumgarner rolls along: Until Saunders homered, Bumgarner was in line to win his fourth consecutive game. San Francisco's ace yielded one run, trimming his ERA in his last four starts to 2.03.

Ever the perfectionist, Bumgarner said he felt himself "scuffle" during his performance, citing his four walks as evidence. But, Posey said, "He's getting some swings on the breaking ball now, which is always a good sign."
SOUND SMART WITH YOUR FRIENDS
Tulowitzki made two errors in a game for the fifth time in his career. The last time it happened was April 17, 2012, which was a span of 401 games.
UPON FURTHER REVIEW
The Giants contested a second-inning ruling that determined Gillaspie was thrown out at first base. A replay review found the call should be overturned, awarding Gillaspie first base.

Gibbons lost a challenge in the top of the 13th inning. Ryan Goins led off with a single to left but he tried to stretch it into a double. Blanco made a strong throw to second and umpire Adam Hamari called Goins out. After a review, it was ruled the call stands because there was not sufficient video evidence to either overturn or confirm the call.

Blue Jays: The Blue Jays will enjoy an off-day Thursday before opening up a three-game series against the Rangers on Friday night in Arlington.
