SAN FRANCISCO (Interstat) — The San Francisco Giants scored all of their runs in the first two innings Monday night and cruised to a 5-0 victory over the Cincinnati Reds at Oracle Park, snapping a five-game losing streak in front of an announced crowd of 31,123.

The game lasted 2 hours, 21 minutes, and the Giants’ victory improved their record to 53-78. The Reds fell to 62-70 with their second straight loss.

Rafael Devers drove in three runs and led the Giants’ offense, finishing 2 for 4 with a home run. Devers, who had homered in his previous game at Atlanta, singled in the first inning and then delivered the decisive blow in the second, a three-run shot to right-center field. That blast extended San Francisco’s lead to 5-0 and effectively put the game out of reach.

The Giants wasted no time manufacturing offense against Reds starter Chase Burns. Drew Gilbert opened the bottom of the first with a ground-rule double to right-center field, and Devers followed with a sharp line-drive single to right, putting runners at the corners. Jung Hoo Lee then singled to center, scoring Gilbert for the game’s first run. Turner Hill followed with a sharp fly-ball double to right, scoring Devers, and Lee was thrown out at home on the play as right fielder JJ Bleday fired to the plate. Burns escaped further damage by striking out Drew Cavanaugh and Nate Furman to end the inning.

The second inning proved far more costly. Shay Whitcomb flew out to center for the first out, and Grant McCray struck out. Christian Koss then singled to right, and Gilbert followed with another double, this one to left field, scoring Koss and putting Gilbert at second. Devers stepped in and launched an opposite-field home run to right-center, his 27th of the season, scoring Gilbert and Koss ahead of him. That gave the Giants a 5-0 cushion and chased Burns from the game after he recorded just five outs.

Burns, who entered with a 14-3 record, took the loss after allowing five earned runs on seven hits and one walk over 2 2/3 innings. He struck out three but was hurt by the Giants’ aggressive approach at the plate. The Reds brought in Julian Garcia, who threw two scoreless innings, striking out one and allowing no hits. Sam Moll added 1 1/3 scoreless innings with one strikeout, and Emilio Pagán worked a scoreless inning while allowing one hit.

The Reds threatened briefly in the third inning. Ivan Johnson walked with one out, and Elly De La Cruz singled to center to put runners at first and second. Sal Stewart then flew out to right, allowing Johnson to advance to third, but Dane Myers struck out to end the threat. Cincinnati did not get a runner past second base the rest of the way.

Devers’ performance was the centerpiece of the game, but San Francisco’s pitching staff played an equally important role in securing the shutout. Carson Whisenhunt started the game for the Giants and worked 2 2/3 innings, allowing two hits and no earned runs while striking out three. Ryan Walker followed with two hitless innings, striking out two. Jason Foley, the winning pitcher, entered in the seventh and threw 1 1/3 innings without giving up a hit, striking out three. Carson Seymour, Reiver Sanmartin and Dylan Smith each pitched an inning of relief, with Seymour striking out two and Smith striking out one. The Giants’ pitchers combined for 11 strikeouts against one walk, and they did not allow a run despite scattering five hits across the game.

The Reds’ offense was shut out for the 11th time this season. Cincinnati managed five hits, with De La Cruz, Tyler Stephenson, Sal Stewart, Eugenio Suárez and Dane Myers each collecting one. Stephenson had a single in the second inning and another in the sixth, but the Reds were never able to string together enough hits to mount a serious rally. They left runners on base in the third, sixth and ninth innings, including two runners in the ninth when Matt McLain flew out to center field to end the game.

The Giants’ defense also contributed to the shutout. In the bottom of the fourth inning, with a runner on first, Gilbert grounded into a double play, erasing any potential momentum. San Francisco turned one double play in the game, and the outfielders made several routine catches to keep the Reds off the bases.

The game’s most important stretch came in the second inning, when Devers’ home run turned a tight 2-0 game into a 5-0 lead. The Reds had shown some fight in the top of the third, putting two runners on with one out, but the Giants’ pitching staff closed the door from that point forward. Whisenhunt, Walker and the rest of the bullpen combined to retire 19 of the final 22 batters they faced, with only a single, a walk and a single reaching base after the third inning.

Cincinnati’s Chase Burns had been one of the National League’s more reliable starters this season, but he struggled with his command Monday night. He threw 13 strikes and 50 balls, an unusually high number of pitches out of the zone, and the Giants capitalized by waiting for good pitches to hit. Devers, in particular, did not miss his pitch, sending his second-inning home run deep into the right-center field stands.

The Giants improved to 3-3 against the Reds this season, having split a three-game series in Cincinnati in April. They will continue the four-game set against the Reds on Tuesday night, with Cincinnati sending a starter to the mound looking to avoid a third consecutive loss. The Reds have lost four of their last five games, while the Giants had dropped five in a row before Monday’s victory.

San Francisco’s recent struggles had been tied to a lack of run production. The Giants had scored three runs or fewer in each of their previous five games, including three consecutive one-run losses on the road. Monday’s outburst was a welcome change for a team that had been shut out twice in its previous eight games.

Devers’ recent performance has been one of the few bright spots for the Giants. Over his last four games, he had collected hits in each, including a home run against Atlanta on Aug. 31 and a two-hit game against Arizona on Aug. 29. His three-RBI night moved him to a team-leading total for the season.

The Reds, meanwhile, will look to regroup after managing only five hits. Cincinnati’s lineup has been inconsistent throughout August, and Monday’s loss was another example of the team’s inability to generate offense against a bullpen that entered the game with an earned-run average above 4.50. The Reds stranded seven runners on base and struck out 13 times as a team.

San Francisco’s Jason Foley earned his first decision of the season, moving to 1-1. He entered the game in the seventh inning with the Giants holding a five-run lead and retired all four batters he faced, striking out three. Foley’s performance was the highlight of a bullpen effort that allowed no earned runs over 6 1/3 innings.

The game was played at Oracle Park, a venue that has traditionally favored pitchers, and Monday’s contest followed that pattern after the early offensive burst. The Giants’ five runs came entirely within the first two innings, and neither team scored after the bottom of the second.

In the ninth inning, the Reds mounted one final attempt. Dane Myers struck out to lead off, but Tyler Stephenson walked to put a runner on first. Suárez singled to left, moving Stephenson to second, and McLain came to the plate representing the tying run. McLain flew out to center field, and JJ Bleday popped out to shortstop to end the game. The Giants’ players celebrated the victory as the final out was recorded, and the announced crowd of 31,123 headed home after a game that lasted just over two hours.

The Reds will send a right-hander to the mound Tuesday in the second game of the series, while the Giants will look to build on their most complete performance in weeks. San Francisco’s pitching staff combined for 11 strikeouts and allowed just one walk, a key factor in the shutout. Cincinnati’s pitchers combined for 13 strikes, 50 balls and 13 balls in play, while the Giants’ pitchers recorded 11 strikes, 31 balls and 11 balls in play.

Interstat’s game simulator had projected a final score of Cincinnati 4, San Francisco 3, with the Reds installed as a 1.5-run favorite. Interstat’s ELO system had given San Francisco a 51.6 percent probability to win. The total score of five runs went over the over-under line of eight.
