Rich Crew’s MLB betting analysis looks at the Braves vs. Red Sox game, considering the wind conditions at Fenway Park and the offensive capabilities of both teams. Read on for his pick.

Sharp Money Take

The Braves opened as slight favorites, but the total has seen some movement, shifting from 9.5 to 9.0 with juice to the over (-108). While this half-run movement might suggest some under money, the change in juice indicates conflicting opinions from sharp bettors. With the wind forecast to be blowing out to right center at 15 mph today, the conditions favor hitters despite recent scoring trends. The moneyline has held relatively stable around -123, presenting value on the home dogs getting plus money.

Key Matchup Analysis

Spencer Schwellenbach (2-3, 3.48 ERA) takes the hill for Atlanta against Boston’s Brayan Bello (2-0, 2.33 ERA). Schwellenbach is coming off a strong 7-inning performance against Washington, but Boston hitters have his number in limited encounters. Current Red Sox are batting a combined .333 (4-for-12) with a remarkable 1.218 OPS against him, including a home run from Rafael Devers who boasts an eye-popping 2.667 OPS in their matchups.

Bello has been effective this season with a 2.33 ERA over his last 5 starts, but his command issues are concerning. He’s averaging just 5.1 innings per start and has walked 14 batters in his last 5 outings (2.8 BB/G), creating high-stress innings and elevated pitch counts (94.6 pitches per outing). These short outings will force Boston to rely heavily on a bullpen that’s already worked 10.2 innings over their last 3 games.

Historically, Bello has handled Atlanta well, going 1-0 with a 2.50 ERA in two career starts against the Braves, but hasn’t faced them since 2023. Current Braves are hitting a combined .283 (13-for-46) against Bello lifetime, suggesting they could get to him early.

Situational Factors

Atlanta has won 4 of their last 6 games, but their road record is troubling at 8-16 this season. The Braves split the first two games of this series, dropping last night’s contest 7-6 despite a late rally. Boston is just 1-4 in their last 5 games overall, getting swept in Detroit before returning home.

The bullpen workload favors Atlanta significantly. The Braves’ relievers have pitched 7 innings in the last 3 games compared to 10.2 innings for Boston’s pen. Atlanta’s available bullpen arms sport a solid 2.61 ERA over 38 innings, while Boston’s available relievers have posted a 3.62 ERA across 64.2 innings.

The under has been cash money in this matchup, going 7-2 in the last 9 meetings between these teams. The under is also 15-4 in Atlanta’s last 19 games overall and 7-1 in their last 8 road games.

Statistical Edges

Boston holds the offensive advantage, scoring 4.85 runs per game (7th in MLB) compared to Atlanta’s 3.98 (21st). However, the Braves’ pitching has been superior, allowing just 3.84 runs per game (8th) versus Boston’s 4.57 (22nd).

Schwellenbach has shown excellent command lately, walking just 3 batters over his last 13 innings while maintaining a strong groundball rate. Meanwhile, Bello has been allowing more flyballs recently with a 4.6 GB:FB ratio that’s dropped considerably from his career norm against Atlanta (6.8).

The Red Sox have been productive at the plate recently with 25 runs over their last 5 games (5.0 per game), but their pitching has been a disaster, allowing a whopping 40 runs (8.0 per game). Atlanta’s offense has been similarly potent, scoring 24 runs in their last 5 (4.8 per game), and their pitching has been exceptional, surrendering just 18 runs (3.6 per game).

Atlanta at Boston Best Bets for 5/18/25

While Atlanta’s season-long pitching numbers look solid, the current matchup suggests runs could be plentiful at Fenway today. Bello’s walk issues and short outings combined with the Red Sox hitters’ success against Schwellenbach set up nicely for an over play. Add in the 15 mph wind blowing out to right center, and we’ve got a recipe for a high-scoring affair.

On the side, Boston as a home underdog offers solid value. The Red Sox have been scoring consistently despite their recent struggles, and Atlanta’s abysmal 8-16 road record makes the plus-money proposition on Boston attractive. The bullpen advantage for Atlanta is neutralized by Boston’s clear edge in batter vs. pitcher matchups.
