SAN FRANCISCO-Matt Duffy put an end to the San Francisco Giants longest game of the season with one swing of the bat.

Duffy doubled over the head of Gerardo Parra in the bottom of the 13th inning, as the Giants came back to defeat the Colorado Rockies 2-1 before a crowd of 41,590, the 425th consecutive sellout at AT&T Park.

Conor Gillaspie scored the winning run after he walked while batting for winning pitcher Derek Law, went to second when Denard Span walked and after Joe Panik struck out for the second out, Duffy’s send the sellout crowd happy.

Panik came up with the play of the game in the top of the 13th inning, as he flipped the ball over his head from his stomach to Brandon Crawford to get Nolan Arenado. Originally, Arenado was called safe, but Bruce Bochy challenged the call was reversed.

Ryan Wolters gave the Rockies the lead, as he doubled just underneath the glove of Brandon Belt at first base and down the line in the top of the 10th inning. DJ LeMahieu scored the only run for the Rockies, as he tripled with one out.

Brandon Belt tripled to leadoff the bottom of the 10th inning, and then scored the tying run when Brandon Crawford singled with one out; however Rockies closer Jake McGee was able to get out of the inning by getting Gregor Blanco to ground into a force out and then Mac Williamson ended the inning by grounding out to DJ LeMahieu at second base.

Cueto pitched 8.1 innings of scoreless baseball, allowing eight hits, walking one and striking out three; however he did not fare in the decision.

Like Cueto, Gray was outstanding for the Rockies, as he pitched seven scoreless innings, allowing just one hit, while walking two and striking out five.

Gray looked amazing, as he did not allow a hit to the Giants until Denard Span led off the bottom of the fourth inning with a single. That would be the only hit that the Giants would manage off of the right-hander.

The only other Giants hits until Belt’s triple against Rockies pitching came off the bat of Brandon Crawford in the bottom of the eighth inning, and Kelby Tomlinson to leadoff the bottom of the ninth. Matt Duffy walked with two outs, but Buster Posey was unable to get the Giants the win, as he grounded into a force play to end the inning and the threat.
