The Arizona Diamondbacks can't salvage anything more than a .500 season, though they'd surely like to treat their fans to a strong home finish after mostly miserable play at Chase Field down the stretch.

They'll look to pick up another victory there Wednesday night against the Colorado Rockies after opening their final homestand in winning fashion.

Arizona (76-81) is 6-12 at home since Aug. 12, the second-worst mark in the majors in that span behind only Cincinnati's 6-19 record. But in the first of six straight home games to conclude the year, the Diamondbacks won 4-3 in 11 innings Tuesday on Phil Gosselin's pinch-hit single after Colorado reliever Brooks Brown walked the bases loaded.

"I was just trying to see something out over the plate," Gosselin said. "You want to contribute any way you can if you're not starting."

They've had little issue winning in Phoenix against the Rockies lately, taking six of the last seven meetings there while batting .316 with 6.9 runs per game. Paul Goldschmidt, who scored Tuesday's winning run, owns a 1.320 OPS with 19 RBIs and 15 runs scored in his last 17 home games against Colorado.

The Rockies (66-91) had their winning streak snapped at three, though Carlos Gonzalez joined teammate Nolan Arenado in the 40-home run club by going deep for the third time in four games. It's the first time two Colorado players have hit that plateau since Vinny Castilla, Larry Walker and Andres Galarraga did it in 1997. They're also competing with Washington's Bryce Harper for the franchise's first NL home run title since Dante Bichette, Galarraga and Walker each won it from 1995-97.

Jose Reyes was 3 for 5 after missing four games due to an Achilles injury.

Chase Anderson (6-6, 4.40 ERA) struck out a career-high 10 over six innings while giving up only a leadoff home run in Arizona's 4-1 loss to the Los Angeles Dodgers last Wednesday. It was his first start in 15 days after he was temporarily removed from the rotation.

"I thought (Anderson) threw as well as we've seen him, as well as probably early in the year when he was dominating," manager Chip Hale said. "It was really good to see, especially after not being out there in competition for a while."

He baffled Colorado in his first three career matchups last year, winning and limiting the Rockies to one run over six innings in each. He's s 0-3 with a 8.65 ERA in five meetings since, however, including a 9-4 road loss Sept. 2. Arenado has homered against him three times this year, while Charlie Blackmon is 5 for 10 with a home run and two doubles this season.

Colorado's Chad Bettis (8-5, 4.38) is 2-0 with a 1.50 ERA in his last three starts, striking out 18 in as many innings. He'll look to overcome a brief yet rough history against Arizona, having surrendered 10 runs in 8 1-3 innings, including four and a career-worst 11 hits over six innings in his club's 5-4 victory Aug. 31.
