San Francisco Giants suffer another heartbreaking loss as Ketel Marte delivers walk-off winner

Could have been the worst loss of the season.

Ketel Marte hit a three-run walk-off homer in the bottom of the ninth to seal the deal giving the D'backs a 5-3 victory. The Giants dropped to 20-29 second-worst in the National League.

Giants skipper Tony Vitello was emotional after the loss, blaming himself saying “it’s on me,” USA TODAY Sports baseball columnist Bob Nightengale reported.“Obviously get a guy on base, lefty hits a line drive to center, and then we’ve got, you know, a runner at first, they decide to take a chance and go for a stolen base at second base, and there’s a catchers’ interference called, and then you’re dealing with the situation we dealt with, with Marte, a switch hitter,” Vitello told reporters after the game, detailing what led to the loss.

"At that point, (Caleb) Kilian had 25 pitches, went with a fresh arm, different look and made the wrong decision, cost us the game,\" he said. Not that (Matt) Gage, I mean, he’s got as good numbers as anybody on our team and he’s gotten it done for us more times than not, but obviously it’s on me.”

The blown save was the Giants’ sixth this season.

The Giants 20-29 record is tied for fifth-worst through 49 games since the franchise moved to San Francisco in 1958. It’s the team’s 49-game start in 2017 when the Giants last started 20-29. That year they went 64-98.

The Giants end their three game set with Arizona on Wednesday May 20. First pitch is 12:40 p.m. PT (3:40 p.m. ET).
