Evan Longoria homered and had four RBIs and Brandon Crawford smacked a three-run double to help the San Francisco Giants record an 8-0 victory over the struggling Arizona Diamondbacks on Tuesday night in Phoenix.

Right-hander Kevin Gausman (5-0) continued his strong season with nine strikeouts in five shutout innings as San Francisco halted a three-game slide.

Nick Ahmed and Pavin Smith each had two hits for Arizona, which has dropped nine consecutive games and 12 of its past 13.

Longoria hit a three-run blast in the third inning and also had a run-scoring double in the seventh. He went 3-for-4 with a walk, falling a triple short of the cycle.

Crawford, Alex Dickerson, Steven Duggar and Mike Yastrzemski added two hits as part of San Francisco's 13-hit attack.

Gausman gave up five hits and two walks before leaving after 97 pitches. The 30-year-old lowered his ERA to 1.53, and he has struck out 76 and allowed just 39 hits in 64 2/3 innings.

Three left-handers completed the nine-hit shutout. Jarlin Garcia struck out four and allowed two hits in two innings, Jose Alvarez gave up a hit during a scoreless eighth and Sam Selman gave up one hit while working the ninth.

Diamondbacks right-hander Corbin Martin (0-2) gave up six runs and five hits in four innings. He walked three and struck out two in his second start of the season.

Yastrzemski led off the game with a single off Martin and Brandon Belt and Longoria drew two-out walks to load the bases. Martin and Crawford waged a fierce battle and Crawford prevailed on the ninth pitch when he sent a full-count fastball into the gap in right-center to give San Francisco a quick 3-0 lead.

The Giants added to the lead in the third as Buster Posey walked and Dickerson doubled to start the inning. Martin struck out Belt before Longoria ripped a 1-2 fastball 444 feet over the fence in straightaway center. The homer was Longoria's seventh in 21 career games at Chase Field.

Longoria laced a two-out double to left-center to make it 7-0 in the seventh. It scored Posey, who had singled to lead off the inning.

Dickerson tripled to start the ninth and scored on a pinch-hit single by Curt Casali.
