After leading 4-0 in the first inning, the San Francisco Giants (75-76) lost to the Arizona Diamondbacks (77-75) in a walk-off 6-5. The Diamondbacks Jordan Lawlar hit an infield single in the ninth inning and Corbin Carroll crossed home plate from third base for the hard-fought win in a walk-off.

This was the Giants fourth loss in a row as the Giants drop two games back for the third spot in the NL Wild Card. The Giants playoff hopes maybe dimming as the regular season is rapidly coming to an end. Less than a week ago San Francisco had it all going on; they were playing some of their best ball of the season and like a thief in the night it all disappeared.

Game recap: The Giants had a great start in the game scoring four runs in the first inning. Taking a 4-0 lead in any game is terrific but needs some back-up from the mound and the cooperation of the defense.

Matt Chapman hit a sacrifice and Heliot Ramos score for the early 1-0 lead. Wilmer Flores singled in the first and Rafael Devers scored pushing their lead out to 2-0. They would extend that lead to 4-0 when Jerar Encarnacion doubled and Casey Schmitt and Wilmer Flores both scored.

The Diamondbacks very nearly tied up the game in the second inning scoring three runs. Blaze Alexander singled Gabriel Moreno home and Adrian Del Castillo hit a home run with Alexander on base and Arizona was within a run 3-4. San Francisco got an insurance run in the third inning taking a 5-3 lead. Wilmer Flores hit a solo home run to left center and the Giants were back in business.

When it looked so promising the Giants would not score for the rest of the game. They’re bats checked out after the third inning. The Diamondbacks scored two runs in the bottom of the fifth inning tying up this game.

Arizona took the tie into the ninth inning looking for a walk-off. It was quick one with Jordan Lawlar singling Corbin Carroll home and that was the ball game in the hoped for walk-off 6-5. The Diamondbacks had taken a 2-0 series lead and the Giants had lost their fourth game in a row.

Game notes: Time may be the San Francisco Giants worst enemy as the 2025 season enters the final weeks. The Giants were looking for a win over the Arizona Diamondbacks Tuesday night after losing the first game of the series Monday night 8-1.

San Francisco has lost four games in a row; every loss sets their playoffs hopes back. Such a disappointment because of the promising turnaround the Giants had seen the past few weeks. Right now it all seems to be going in the wrong direction for the Giants.

Giants starter Tristan Beck threw for three innings allowing five hits, three earned runs, and one strike out. Beck was proceeded by four relievers. The second reliever Trevor McDonald pitched two innings allowed three hits, two runs, a walk and one strikeout. All the damage was done by the D-Backs as the Giants lost by a run Tuesday night.

In Wednesday’s game three the Giants will try to avoid a sweep at the hands of the Diamondbacks. First pitch for that game is scheduled for 12:40 PM PT.

Justin Verlander will take the mound for San Francisco. He has a 3/10 win -loss record and a 3.94 ERA. Arizona will start Brandon Pfaadt. He has a 13-8 win/loss record and a 5.31 ERA. The Giants will try to put an end to their losing streak as well as avoiding a sweep.
