Big comeback squandered

DENVER — The Giants played at Coors Field on Memorial Day and lost. They also fell here on Independence Day and completed the holiday trifecta with Monday’s 9-8 Labor Day defeat.

Rosh Hashanah starts Sunday night. Happily for the Giants, they will be flying home from Milwaukee.

For the 19th time this season, which matches the worst in the majors, the Giants lost a game in which their opponent scored the winning run in its last atbat. They overcame deficits of 4-0 and 7-2, all the runs charged to Madison Bumgarner, and had a dream offensive day after totaling five hits in two weekend losses to the Mets. Gorkys Hernandez homered. Evan Longoria had three RBIs, two on a triple.

Chase d’Arnaud and Nick Hundley doubled and scored. In a three-run eighth inning, the Giants took an 8-7 lead on the club’s first back-to-back pinch homers since Barry Bonds and

Shawon Dunston in 2001. The Alen Hanson and Chris Shaw homers made the Giants’ dugout euphoric, a temporary high, as the Rockies scored twice off Tony Watson in the bottom half on Noel Cuevas’ single past a drawn-in infield.

Bumgarner had the second worst of his 15 starts here, allowing all the runs on two Trevor Story homers (good for five RBIs) and another by DJ LeMahieu. Each hit a two-run shot in the first with no outs. The crucial play was a Nolan Arenado groundball that could have ended the fifth inning with the Giants down 4-2. Instead, second baseman Kelby Tomlinson let it shoot off his glove into center for an error. Story then hit his second homer. Belt out: Brandon Belt did not start because of soreness in his right knee, which he injured in Seattle on July 25, costing him 17 games. He did strike out in the ninth inning.

Belt had the knee cleaned out in an arthroscopic procedure after 2015 and might need a similar operation this offseason. His recovery time after the first one was a month.

Briefly: Steven Okert and Pierce Johnson, who were recalled from Sacramento with pitcher Casey Kelly, each threw a shutout inning . ... D’Arnaud started at first base for the first time in his career.
