DENVER (Interstat) — Kyle Karros hit a three-run homer in the bottom of the eighth inning Sunday afternoon, lifting the Colorado Rockies to a 7-6 comeback victory over the San Francisco Giants at Coors Field.

The Rockies trailed 6-4 entering the eighth after the Giants had built a lead with two home runs from Rafael Devers and another from Drew Gilbert. But Colorado mounted its decisive rally against the San Francisco bullpen, scoring three runs on three hits to erase the deficit and hand the Giants their second loss in three games of the series.

Victor Vodnik pitched a scoreless eighth inning for Colorado to earn the win, improving to 3-3. Jordan Romano worked a perfect ninth for his fifth save. Dylan Smith, making his major league debut for San Francisco, took the loss after allowing three runs on three hits in the eighth inning without recording an out. Smith fell to 0-1.

The game, played in front of an announced crowd of 25,548, lasted 2 hours, 48 minutes. San Francisco dropped to 37-52, while Colorado improved to 37-54.

Colorado opened the scoring in the first inning. Jake McCarthy led off with a triple to center field, then scored on a groundout by Hunter Goodman. After a single by TJ Rumfield and another single by Troy Johnston advanced Rumfield to third, Kyle Karros struck out, but Johnston was caught stealing later in the inning to limit the damage. The Rockies took a 2-0 lead.

The Giants answered in the second. Willy Adames singled with one out, and Drew Gilbert followed by crushing a two-run home run to right-center field, his fourth of the season. That tied the game 2-2.

Colorado regained the lead in the bottom of the second. Edouard Julien singled, and Brett Sullivan doubled to right field, scoring Julien to make it 3-2. But the Rockies could not add more as Ezequiel Tovar popped out and Jake McCarthy and Mickey Moniak struck out and popped out, respectively.

The Rockies extended their lead in the third. Hunter Goodman singled, and after a single by TJ Rumfield, Troy Johnston hit a sacrifice fly to left field to score Goodman, pushing Colorado ahead 4-2.

San Francisco cut the deficit in the fourth. Devers led off with a solo home run to right-center field, his 17th of the season, making the score 4-3. The Giants then had a chance to tie or take the lead after a walk to Bryce Eldridge and a double by Gilbert, but Drew Cavanaugh popped out to end the inning.

The Giants tied the game in the fifth. Casey Schmitt led off with a solo home run to left field, his 17th of the season, evening the score at 4-4. Two batters later, Devers hit his second solo homer of the game, a drive to right field for his 18th of the season, giving San Francisco its first lead of the afternoon at 5-4.

San Francisco added an insurance run in the sixth. Adames walked, and after a fielder’s choice and an error by shortstop Ezequiel Tovar, Adames advanced to third. Gilbert singled to center field, scoring Adames to make it 6-4. But the Giants could not add more when Drew Cavanaugh bunted into a sacrifice and Luis Arraez lined into a double play.

The score remained 6-4 until the Rockies’ decisive eighth inning. Smith entered from the bullpen to start the bottom of the eighth. He struck out Hunter Goodman for the first out, but then gave up a double to TJ Rumfield. Troy Johnston was hit by a pitch, putting runners at first and second. That brought up Karros, who launched a 1-1 pitch over the left-center field wall for a three-run home run, his seventh of the season, giving Colorado a 7-6 lead. The Rockies added no more as Edouard Julien grounded out and Brett Sullivan lined out.

In the ninth, the Giants mounted a final threat. Jung Hoo Lee singled with two outs, but Willy Adames struck out swinging to end the game.

Key performances included Gilbert’s 4-for-4 afternoon with a home run and three runs batted in. Devers went 2-for-5 with two home runs and two RBI. For Colorado, Karros finished 1-for-4 with a home run and three RBI. The Rockies’ bullpen combined for three scoreless innings, with Vodnik and Herget each tossing a perfect inning and Romano closing it out. San Francisco’s Erik Miller pitched 1 2/3 scoreless innings, allowing no hits and striking out two.

The Giants’ starter, Tyler Mahle, worked 4 1/3 innings, allowing four runs on eight hits while striking out five. The Rockies’ starter, Tanner Gordon, lasted five innings, surrendering five runs on six hits with seven strikeouts.
