Mike Yastrzemski came with the biggest hit of the game when the San Francisco Giants needed it the most.

Yastrzemski hit a grand slam that landed into McCovey Cove that propelled the Giants to an unbelievable 9-8 victory over the Arizona Diamondbacks at Oracle Park.

This was the seventh straight win for the Giants over the Diamondbacks and are now 12-2 since the beginning of the 2020 season and have outscored them 74-41 during that time.

Things did not start good for the Giants, as Zack Littell could not get a batter out and the Diamondbacks jumped out to a quick 4-0 lead in the top of the first inning.

Sammy Long came on to replace Littell, and the Diamondbacks added three more runs in the top of the second inning to take a 7-0 lead.

These are not the Giants of yesteryear, as they began to mount their comeback in the bottom of the second inning.

Donovan Solano drove in the first run for the Giants, as he grounded out to Josh Rojas at second base that allowed Wilmer Flores to easily score from third base and then Steven Duggar hit a two-run home run to cut the Diamondbacks lead down to 7-3.

Former Oakland As outfielder Josh Reddick added what turned out to be the last Diamondbacks run of the night, as he grounded out to Long that allowed Asdrubal Cabrera to score from third base.

The Giants began to mount their comeback, as Solano drove in his second run of the game, as he pulled the ball into left field that scored Brandon Belt to cut the lead in half.

Jason Vosler then got the Giants within three, as he beat out an infield single to score Solano.

Then the Giants came up with could be one of the biggest innings of the season, as Belt doubled to right field, then Solano singled on a 2-0 pitch and after Mauricio Dubon flew out to left field and then Lamonte Wade, Jr., grounded into a force play and Gabe Kapler gambled, as he sent his last pinch hitter on the bench and Curt Casali drew a pinch-hit walk to bring Yastrzemski to the plate and on the fourth pitch he saw from Humberto Castellanos, Yastrzemski hit his first career professional grand slam to give the Giants a dramatic comeback victory.

Jimmie Sherify pitched a perfect eighth inning, as he picked up his first win of the season for the Giants.

Tyler Rogers nailed it down in the top of the ninth inning, as he set the Diamondbacks down in order with a strikeout to pick up his ninth save of the season.

Littell last just six batters, as he allowed four runs on four hits, walking two and not striking out a batter and then Long came on to replace Littell.

Long ended up going five innings, allowing four runs on five hits, walking one and striking out three before giving way to Conor Menez, who allowed two hits and struck out two in his only inning of work and then Jarlin Garcia gave up a hit and strikeout in his only inning of work before Sherfy came on in the top of the eighth inning.

It was a tough no-decision for Alex Young, who went four innings, allowing three runs on five hits, walking one and striking out two.

The Diamondbacks bullpen let them down, as they were unable to get the Giants out, as they the trio of Conor Martin, Joe Mantiply and Castellanos went the final four innings, allowing five runs on seven hits, including that grand slam to Yastrzemski that proved to the game-winning hit.

NOTES: This was the biggest comeback by the Giants since they trailed the Cincinnati Reds 8-0 at Great American Ballpark on May 3, 2019, and ended up winning 12-11 in 11 innings.

When he hit a home run on Monday night, Brandon Crawford reached another milestone, as he became the quickest Giants shortstop since at least 1901 to reach 15 home runs in a season, as he reached the plateau in the Giants 66th game of the season.

Sadly, this was the 21st consecutive loss on the road for the Diamondbacks, and their 12th loss in a row overall.

Their last win away from Chase Field for the Diamondbacks came on April 25 against the Atlanta Braves at Truist Park, as Madison Bumgarner threw a seven-inning no-hitter; however, the no-hitter does not count as a no-hitter in the MLB record book.

UP NEXT: Anthony DeSclafani looks for his seventh win of the season, as he heads to the mound on Wednesday night, while Merrill Kelly goes to the mound for the Diamondbacks.
