Rafael Devers hit his first opposite-field home run after joining the Giants against his former team.

Rafael Devers' "revenge journey" has begun.

Six days after completing a major trade with the Red Sox, Devers launched his first home run for the Giants — facing none other than his former team. On Saturday afternoon, in a 3-2 victory over the Red Sox at Oracle Park, Devers faced Boston right-hander Brayan Bello's fastball and sent it to left field for a two-run shot. Bello is his close friend and fellow Dominican Republic native.

"I'm really happy," Devers said in Spanish, "The most important thing is that I can contribute to the win. I'll give 100% effort to keep helping the team win."

Heliot Ramos started the scoring in the first inning with a home run off Bello, and then Devers extended San Francisco's lead with this milestone home run in the bottom of the third inning. According to Statcast, this 16th home run of the season traveled 370 feet with an exit velocity of 105.5 mph, eliciting loud cheers from the 39,027 fans in attendance.

"We've seen him do this many times when he was with the Red Sox," Giants outfielder Mike Yastrzemski said on Wednesday. "He's the kind of player who can easily become the face of the team. He has tremendous talent, incredible swing speed, and impeccable plate discipline. That's the kind of performance you want to see in the middle of the lineup any day."

According to Stats, LLC, Devers hit his last home run as a Red Sox against the Yankees on Monday, just hours before being traded to the Giants (in exchange for left-hander Kyle Harrison, right-hander Jordan Hicks, 2024 first-round pick James Tibbs III, and pitching prospect José Bello). After today's home run for San Francisco, he became the ninth player in MLB history to hit home runs against the same team within seven days.

"When he hits, it's like the weight has been lifted off his shoulders," right-hander Landen Roupp said after his six scoreless innings with only three hits allowed earned him the win. "We're expecting more contributions from him in that regard. It's great to have him on the team, and I think he'll be a huge help."

Devers said hitting a home run against the Red Sox was "nothing special," but he had to set aside some emotions when facing Bello, a former teammate for four seasons.

"He's my brother, but we know once we step on the field, it's a different story," Devers said. "We're just competing; whoever wins, wins."

"A very good friend," Bello said of Devers. "He’s always there for me when I’m struggling, always giving me advice; he’s a great friend. I feel good; I challenged him, he hit a home run, but I also got him out twice. He’s a fantastic hitter."

In his first five games with the Giants, Devers has 20 at-bats with 4 hits, including 1 double and 3 RBIs. The 28-year-old slugger went 0-for-5 in the series opener against the Red Sox, where the left-handed team lost 7-5, but in the third inning, he hit a deep fly ball 385 feet to left-center that was caught at the wall by center fielder Ceddanne Rafaela, just missing the home run.

Devers has hit many long balls at Fenway Park with impressive opposite-field power, but he stated that he doesn't plan to change his hitting strategy now that he’s playing in the less hitter-friendly Oracle Park.

"I don't need to change anything," Devers said on Friday. "If I make solid contact, the ball will go out, no matter the ballpark. I'm a power hitter."

Roupp exited after throwing 90 pitches, leaving with a 3-0 lead. Although the Red Sox scored two runs in the top of the ninth, closer Camilo Doval induced Romy Gonzalez to ground out, leaving the runner stranded at third and ending the game.

Devers' tumultuous week will conclude on Sunday with a decisive game against his former team, but the Giants hope this new star can turn the page and continue to focus on settling down in San Francisco.

"Since he got here, it seems nothing has affected him," manager Bob Melvin said. "He's gone through so much: being traded from Boston to here, and then today's game. Despite all that, he has looked comfortable and happy from the start. He has always been the same person."
