Braves vs Red Sox Expert betting analysis and predictions
Braves Aim to Continue Hot Streak as Series Concludes at Historic Fenway
The surging Atlanta Braves (23-22, 3rd in NL East) look to maintain their momentum when they face the slumping Boston Red Sox (22-24, 2nd in AL East) in Sunday’s series finale at iconic Fenway Park. First pitch is scheduled for 1:35 PM Eastern time, with Atlanta seeking their fifth win in six games while Boston aims to snap a troubling four-game losing streak.
This interleague matchup features an intriguing pitching duel between Atlanta’s emerging right-hander Spencer Schwellenbach (2-3, 3.31 ERA) and Boston’s promising youngster Brayan Bello (2-0, 2.33 ERA). The Braves claimed the series opener with a convincing 4-2 victory on Friday behind former Red Sox ace Chris Sale‘s dominant return to his old stomping grounds.
Schwellenbach Seeks Fenway Redemption Against Resurgent Red Sox Lineup
Spencer Schwellenbach makes his 10th start of the 2025 campaign, looking to build on his solid season while exercising some demons at Fenway Park. The 25-year-old right-hander’s lone career appearance against Boston came last season at this very venue – and it was one to forget. Schwellenbach was tagged for six runs on seven hits in just 4.2 innings, exposing vulnerability against Boston’s disciplined approach.
However, Schwellenbach has shown improvement in recent weeks, posting a respectable 1-1 record with a 4.32 ERA and a 1.26 WHIP over his last three starts. His four-pitch mix featuring a mid-90s fastball and devastating slider has generated a career-best 9.3 K/9 rate this season, though control issues (3.2 BB/9) have occasionally led to elevated pitch counts limiting his innings.
The Braves’ pitching staff has been remarkably consistent lately, allowing three runs or fewer in six of their last eight contests. This stellar performance has coincided with Atlanta’s offensive resurgence, scoring four or more runs in five consecutive games despite the continued absence of superstar Ronald Acuña Jr.
Key Stat: Atlanta’s bullpen has been dominant in May, posting a collective 2.87 ERA – third best in the majors during this stretch.
Bello Aims to Continue Breakout Season Against Potent Atlanta Lineup
Boston counters with their own rising star in Brayan Bello, who has emerged as a legitimate frontline starter in his third MLB season. The Dominican right-hander brings a perfect 2-0 record and sparkling 2.33 ERA into Sunday’s contest, his sixth start of 2025 after beginning the season in the bullpen.
Bello has particularly excelled at Fenway Park this season, where he’s posted a 1.98 ERA while limiting opponents to a .217 batting average across 27.1 innings. His sinker-changeup combination has generated an impressive 56.8% ground ball rate, perfect for neutralizing Atlanta’s power-hitting lineup.
In his lone career start against the Braves (at Fenway in 2023), Bello delivered a quality start, allowing three runs over six innings while striking out four. He’ll need to be especially careful with Atlanta’s Matt Olson, who has tormented Boston pitching throughout his career with a .321 average and seven home runs in 19 games against the Red Sox.
Boston’s pitching staff has struggled recently, surrendering four or more runs in four consecutive games, including a disastrous 14-run outburst by Detroit to begin their previous series.
Key Stat: The Red Sox are 5-1 in Bello’s last six starts dating back to last September.
Offensive Analysis: Atlanta Finding Rhythm Without Acuña
Atlanta’s offense has shown remarkable resilience despite missing superstar Ronald Acuña Jr., who continues rehabbing from last season’s knee injury. The Braves have scored 29 runs over their past five games (5.8 runs per game), significantly outpacing their season average of 4.2 runs per contest.
Veteran catcher Sean Murphy has been instrumental in this surge, batting .327 with three home runs and 12 RBIs over his last 14 games. First baseman Matt Olson has also heated up, collecting hits in nine straight games while providing consistent power from the cleanup spot.
For Boston, the offensive struggles have been pronounced during their current four-game skid, averaging just 2.75 runs per game. Outfielder Jarren Duran remains their most consistent performer, maintaining a .304 average while collecting multiple hits in four of his last six games.
The Red Sox will need increased production from sluggers Masataka Yoshida and Rafael Devers, who have combined for just three extra-base hits over the past week.

Weather and Ballpark Factors
Sunday’s forecast calls for partly cloudy skies with temperatures in the mid-70s and light winds blowing out to left field at 8-10 mph. These conditions should slightly favor hitters, particularly left-handed power bats like Atlanta’s Matt Olson and Boston’s Rafael Devers.
Fenway Park’s unique dimensions (302 feet to right field, but with a 37-foot high wall) create interesting strategic dynamics. The Red Sox have historically constructed their lineup to take advantage of the Green Monster in left field, while visiting teams often struggle with its peculiarities.
Final Prediction and Betting Analysis
The Braves enter as slight -115 favorites on the moneyline, with the total set at 8.5 runs. Given Atlanta’s recent offensive surge and Boston’s pitching struggles, there’s compelling value in backing the Braves and considering the over.
Prediction: Atlanta continues their hot streak behind Schwellenbach’s redemption effort and a balanced offensive attack. The Braves secure a 6-3 victory, easily surpassing the total while covering the spread.
Best Bet: Braves -1.5 runs (+145) offers excellent value given Boston’s recent defensive issues and Atlanta’s momentum.
Value Play: Over 8.5 runs (-110) merits strong consideration with wind conditions favoring hitters and both offenses showing potential for big innings.
Expert Insights
Is Spencer Schwellenbach’s previous struggle at Fenway Park a major concern? While Schwellenbach’s previous Fenway outing was troublesome, it came during his rookie season when he was still adapting to major league hitters. His significantly improved command and expanded pitch repertoire this season suggest he’s better equipped to handle Boston’s lineup. Additionally, the Red Sox offense has struggled significantly more this season compared to when they faced Schwellenbach last year.
How significant is Ronald Acuña Jr.’s absence for Atlanta’s chances? Remarkably, Atlanta has adapted well to life without their superstar. The emergence of prospects like AJ Smith-Shawver and improved production from veterans like Sean Murphy and Matt Olson have helped compensate for Acuña’s absence. The Braves have gone 7-3 in their last 10 games despite missing their MVP, demonstrating impressive depth throughout their roster.
Could Boston’s home-field advantage swing this matchup? Fenway Park typically provides Boston with one of baseball’s strongest home-field advantages, but the Red Sox are just 11-13 at home this season compared to 11-11 on the road. This suggests their traditional Fenway edge has been somewhat neutralized in 2025, making this a less significant factor than in previous seasons.
What’s the impact of Boston’s recent bullpen workload? The Red Sox relief corps has been taxed significantly during their current losing streak, throwing 16.2 innings over their last four games. This fatigue factor could prove crucial if Sunday’s game remains close into the later innings, potentially giving Atlanta’s more rested bullpen a decisive advantage.
Should weather conditions affect betting strategies? With winds blowing out to left field at Fenway, fly ball pitchers become particularly vulnerable. Schwellenbach’s 42.7% ground ball rate gives him a slight advantage over Bello (38.9%) in these conditions. Bettors should consider this when evaluating the total, as conditions appear favorable for exceeding the 8.5 run line.
