SAN FRANCISCO-Despite blowing the lead on three different occasions, the San Francisco Giants were able to muster a run in the bottom of the ninth inning to give Bruce Bochy an historic win.

Conor Gillaspie lined a double to right field that scored Ramiro Pena from second base with one out in the bottom of the ninth inning, as the Giants defeated the Philadelphia Phillies 8-7 before a crowd of 41,479, the 446th consecutive regular season sellout at AT&T Park.

This was the Giants seventh walk-off of the season, the most in the majors and their first since June 11 versus the Los Angeles Dodgers.

With the victory, Bochy became just the fourth manager in New York/San Francisco Giants history to win 800 games, joining John McGraw, who won a team record 2,583 from 1902-1932, Bill Terry, who managed the club from 1933-1941 and won 823 games during that nine-year stretch and Dusty Baker, who won 840 games for the Giants from 1993-2002.

“McGraw has nothing to worry about,” said Bochy.

It was a rare off day for Johnny Cueto, who matched his season-high in earned runs, as he gave up six earned runs in six innings of work. This was the third time this season that Cueto allowed six earned runs in a game, April 10 versus the Los Angeles Dodgers and on May 2 against the Cincinnati Reds.

Cueto went six innings, allowing six runs on eight hits, walking two and striking out two, as he did not fare in the decision.

Angel Pagan continued his hot hitting, as he went 4-for-5 at the plate to pickup his first four-hit game since April 25, 2015 against the Colorado Rockies at Coors Field. During the three-game series, Pagan went 8-for-13 (.615) with four batted in.

Today was one of the best days I have felt since I came back,” said Pagan.

The Phillies came back from deficits of 5-1, 6-5 and 7-6 before Pena scored on a Gillaspie double with one out in the bottom of the ninth inning.

Phillies pitcher Aaron Nola lasted just 3.1 innings, giving up five runs on 10 hits and striking out four. Nola hit three batters, including hitting back-to-back batters in the bottom of the third inning, where the Giants scored four runs to take a 5-1 lead.

The bullpen trio of Derek Law, Josh Osich and Cory Gearrin pitched the final three innings, allowing just one run on four hits and struck out one. Gearrin pitched the ninth inning to pickup his third win of the season.
