PITTSBURGH — Ketel Marte and Alex Avila each hit two-run homers and the Arizona Diamondbacks scored eight runs in the first three innings to power their way to a 9-3 victory over the Pittsburgh Pirates on Thursday night.

Marte's blast capped a three-run first, while Avila's shot in the third extended the NL West-leading Diamondbacks' advantage to 8-0.

Jon Jay doubled in each of the first two innings, the second of which drove in two runs. The center fielder is hitting .340 in 13 games since being acquired June 6 from Kansas City in a trade.

Staked to the early cushion, Zack Godley (8-5) won his third straight start. He gave up three runs — two earned — and four hits in six innings with five strikeouts and three walks.

Avila finished with three RBIs as he also doubled home a run in the ninth.

Chad Kuhl (5-5) lasted just two-plus innings and was lifted following Avila's homer. Kuhl was tagged for eight runs and eight hits after allowing three earned runs or less in seven of his previous eight starts.

Pittsburgh rookie Austin Meadows had three hits.

Daniel Descalso's sacrifice fly brought home the game's first run before Marte followed with his sixth home run into the right-field stands. Paul Goldschmidt singled in Jay in the second to make it 6-0.

Francisco Cervelli hit an RBI single in the fourth inning for the Pirates. Starling Marte doubled in a run and scored on Colin Moran's sacrifice fly in the sixth.

The Diamondbacks have scored 35 runs in going 3-1 against Pittsburgh this season.
