Tyler Locklear and Alek Thomas homered, Brandon Pfaadt tied a career high with his 11th victory, and the Arizona Diamondbacks beat the San Diego Padres 6-2 in Phoenix on Monday.

Corbin Carroll and Lourdes Gurriel Jr. had two hits and two RBIs apiece as the Diamondbacks extended their winning streak to three games following a six-game skid that precipitated their trade-deadline moves.

Locklear, obtained from the Seattle Mariners in the Eugenio Suarez deadline deal, hit his first homer for Arizona in his fourth game. Thomas went deep in the eighth and had his fourth straight multi-hit game.

Jackson Merrill and Jake Cronenworth had the Padres' RBIs, and Ramon Laureano collected two of the team's six hits. San Diego had won seven of eight.

Pfaadt (11-7) gave up two runs and five hits in 5 2/3 innings, leaving after Cronenworth's single made it 5-2 in the sixth. He struck out four and walked three in his second victory over the Padres this season. He finished 11-10 last year.

Kyle Backhus pitched two innings for his first career save.

Padres first baseman Luis Arraez went 0-for-3 with a walk, ending his career-high 16-game hitting streak. He struck out swinging against Pfaadt in the fifth.

JP Sears (7-10) gave up five runs on 10 hits in five innings in his first start for the Padres after being obtained at the deadline. He struck out four and walked one.

The Diamondbacks scored in each of the first four innings off Sears and led 5-1 after five.

Gurriel followed singles by Ketel Marte and Carroll with an RBI single in the first, and Carroll's sacrifice fly in the second made it 2-0.

Merrill and Machado wired two-out doubles in the third, the first hits off Pfaadt, to make it 2-1.

Locklear's homer with one out in the third was measured at 393 feet for a 3-1 lead. His previous two homers came with the Mariners last summer.

Carroll and Gurriel drove in runs in the fourth to make it 5-1.
