BOSTON -- Diamondbacks starter Archie Bradley made one mistake to a hitter.
His right fielder didn't help him, either, making one on a routine flyball later in the same inning.
Sandy Leon had a solo shot to start Boston's three-run fifth inning and right fielder Socrates Brito misplayed the fly for an error later, helping the Red Sox to a 6-3 victory over Arizona on Saturday night.
Trailing 3-1, the Red Sox charged ahead with the runs that were keyed by Brito charging for the flyball and letting it drop next to him. Leon hooked his homer around the Pesky Pole, Andrew Benintendi had an RBI double off the Green Monster after Brock Holt reached on the error and Mookie Betts' grounder bounced over third baseman Jake Lamb for an RBI single.
"Brito just couldn't get the ball," manager Chip Hale said. "It looked like he was there in time."
Bradley (4-8) allowed six runs -- four earned -- in 5 1/3 innings.
"The error's not an issue. It's still our job to go get guys out," Bradley said. "They did a good job. They're a good offense. There's a reason they're one of the best offenses in the big leagues -- and when you make mistakes they make you pay for it."
Michael Bourn had two singles and an RBI for the Diamondbacks. They had won four of five.
Holt hit a two-run homer, rookie Benintendi and Dustin Pedroia each had two hits and drove in a run for Boston, which won its second straight after losing four of five.
Robbie Ross Jr. (2-2) worked an inning of relief for the win after starter Clay Buchholz gave up three runs over 4 1/3 innings in a spot start. Craig Kimbrel worked the ninth for his 19th save after former Arizona closer Brad Ziegler entered and escaped a bases-loaded, no-out jam in the eighth.
Demoted to the bullpen twice this season, Buchholz made his first start since early July on the eve of his 32nd birthday because knuckleballer Steven Wright was scratched on Thursday after jamming his pitching shoulder diving back into second during an interleague game.
Holt homered over Boston's bullpen to make it 6-3 and chased Bradley in the sixth.
Arizona had moved ahead by scoring twice in the fourth and once in the fifth.
Buchholz held the Diamondbacks hitless until Bourn's one-out single in the fourth. Bourn later scored on a groundout and Rickie Weeks Jr. added an RBI single, making it 2-1. Bourn had an RBI single in the fifth.
Former Diamondbacks closer Ziegler came in with the bases loaded in the eighth and struck out all three batters on 10 pitches -- all strikes.
He was acquired by Boston on July 9 for two minor leaguers.
Pedroia went behind second base in the seventh to snag Jean Segura's grounder and flipped it from his glove to SS Xander Bogaerts, who fired to first to complete a DP.
Diamondbacks: Manager Chip Hale said the club hopes to learn more about RHP Rubby De La Rosa's injury after he was sent for an MRI on Friday. The righty has been on the DL after elbow inflammation since May 26.
Red Sox: 2B Pedroia was back in the starting lineup after leaving Friday's game with flu-like symptoms. ... CF Jackie Bradley Jr. was out, both nursing a sore big toe after fouling a ball off his foot a couple of games ago and resting after playing 110 of the club's 114 games. ... Manager John Farrell said Wright threw again Saturday, but "he's not completely symptom free and the next step will be on Monday.
Diamondbacks: RHP Zack Greinke (11-3, 3.67 ERA) looks to continue his solid run in the series finale on Sunday. He's 8-0 with a 2.47 ERA in his last 10 starts.
Red Sox: RHP Rick Porcello (15-3, 3.40) hopes to continue his startling success this season in Fenway Park on Sunday. The righty is looking to become the first Red Sox pitcher since Dave "Boo" Ferriss in 1946 to win his first 12 decisions in a season at home. Ferriss went 13-0 at Fenway that year.
