PHOENIX (AP) - Madison Bumgarner posted a win against his former team and the Arizona Diamondbacks beat San Francisco 8-3 Monday, handing the Giants their fifth straight loss.
Buddy Kennedy drove in a pair of runs and Cooper Hummel scored twice for Arizona. The Giants have lost 11 of 14.
Last season, the Giants went 17-2 against Arizona in winning the NL West title. But in the first of their 19 meetings this year, Bumgarner (4-8) and the D-backs prevailed.
Bumgarner, now in his third season with Arizona after helping the Giants win three World Series championships, allowed three runs in five innings. The 32-year-old lefty struck out four and walked three.
Bumgarner gave up a two-run single to LaMonte Wade Jr. in the first, then settled in. He was pulled after 100 pitches, and is now 2-1 lifetime against the Giants.
Carlos Rodon (7-5) gave up four runs in five innings, striking out seven.
Kennedy hit a tying, two-run single in the first. A series of Giants misplays in the second helped Arizona score two more - Rodon was late covering first on an infield single, San Francisco then botched a bunt and catcher Curt Casali made a throwing error on a steal.
Arizona led 4-3 when Kennedy greeted reliever Tyler Rogers in the sixth with an infield single. Josh Rojas hit an RBI double and scored on Daulton Varsho's single.
David Villar made his major league debut for the Giants, batting seventh and playing second base. On the first pitch he saw, he lined a double off the fence in right-center field. He later had an RBI single.
Villar, the Giants' 11th-round draft pick in 2018 from South Florida, was batting .284 with 21 homers and 62 RBIs in 66 games at Triple-A Sacramento. He led the Pacific Coast League in home runs.
Giants: SS Brandon Crawford (left knee inflammation) is eligible to come off the injured list on Tuesday. Manager Gabe Kapler said "all systems are go" for Crawford's return.
Diamondbacks: RHP Ian Kennedy (right calf) was placed on the 15-day injured list just before the game. Arizona recalled RHP Keynan Middleton from Triple-A Reno to replace him. Kennedy, 37, has a 3.58 ERA this season in a setup role. He left Sunday's game at Colorado after retiring one batter in the eighth inning.
LHP Alex Wood (5-7, 5.03) will start for the Giants on Tuesday. The Diamondbacks have not yet named a starter.
