PHOENIX -- J.D. Martinez continued his red-hot performance in the month of September with a 3-for-4, six-RBI performance Tuesday, carrying the D-backs to an 11-4 win over the Giants at Chase Field.
Martinez roped a two-RBI double in the first inning to give the D-backs a 2-0 lead and then blasted a grand slam in the second to bust the game wide open. Martinez has 15 home runs in the month of September and is one homer shy of tying Ralph Kiner's National League record for most long balls in the month of September
"I'm just glad he's on our team," Arizona manager Torey Lovullo said. "I've watched him from the other dugout for a couple years. I do know why he's stayed locked in; it's the dedication to his art. The amount of time he spends paying attention to the smallest details that are going to help him be successful, they play out every single day. What he's doing is not by accident."
D-backs starter Robbie Ray held the Giants to two unearned runs on three hits over five innings. He struck out five San Francisco batters and was pulled after 80 pitches. With the win, Ray notched 15 wins for the first time in his career. He is tied for fifth in the National League in wins despite missing nearly a month of the season.
Lovullo did not announce if Ray will start Sunday in Arizona's regular-season finale in Kansas City. The D-backs are still exploring options as to whether they want to save Ray for emergency duty in the National League Wild Card Game on Oct. 4 or set him up to pitch on normal rest for the potential first game of the NL Division Series on Oct. 6.
In his final start for the Giants this season, Matt Moore gave up eight runs (seven earned) on five hits and three walks in 1 1/3 innings. The grand slam he surrendered to Martinez was the 27th home run he has allowed this season, adding to his career-worst total. His ERA, which was an NL-worst 5.20 entering the game, ballooned to 5.52.
"I think I got carried away with effort level," Moore said, explaining that he prefers to gradually build up the energy he expends.
Concerned with Moore's confidence after he recorded the third-shortest outing of his career, Giants manager Bruce Bochy said he'll try to give the left-hander a relief stint during the season-ending series against San Diego. A scoreless inning or two, said Bochy, would propel Moore into the offseason feeling better about himself. Moore approved of Bochy's plan before the manager could explain it to him.
"That's kind of taking the words out of my mouth. I hope that is the case," Moore said.
MOMENTS THAT MATTERED Robbie rolls up double play: Ray got off to a rocky start in the first inning when he surrendered a leadoff walk to Hunter Pence and then a single to Joe Panik. But Ray bailed himself out by getting Gorkys Hernandez to roll into a 6-4-3 double play and then got Buster Posey to ground out to short to end the inning. Ray held the Giants hitless for the next three innings until Tim Federowicz launched a two-run homer in the fifth.
"I felt great," Ray said. "I felt like everything was working for me. I got a couple of key ground balls -- that double play in the first inning was huge, and then with the runner on third, getting the ground ball to get out of the inning and getting out with 17 pitches was pretty big."
Not just dingers: After Ray fought his way out of trouble in the first, it didn't take long for the D-backs to take back momentum of the game. A.J. Pollock reached on a walk in the first, and Paul Goldschmidt followed with a single before Martinez stepped to the plate and cracked a one-out, two-run double.
WHAT'S NEXT Giants: A Wednesday matinee starting at 12:40 p.m. PT will conclude the three-game series between the Giants and D-backs. The D-backs have proven challenging for Giants starter Jeff Samardzija, who's 1-3 with a 5.13 ERA in four starts against them this year.
D-backs: The D-backs will play their last regular-season home game Wednesday at 12:40 p.m. MST when they close out a three-game set with the Giants at Chase Field. Braden Shipley will make his third start of the season for Arizona. He is 0-1 and has allowed eight runs in nine innings as a starter in 2017.
