Rays vs Red Sox Prediction & Best Bets | Tampa Bay Looks to Continue Boston’s Woes

by | Jun 9, 2025 | mlb

Shane Baz Tampa Bay Rays Starting Pitcher

The Tampa Bay Rays (37-33) head to Fenway Park to take on the struggling Boston Red Sox (32-35) in what should be an exciting AL East matchup. The Red Sox are coming off an impressive series win against the Yankees, but their overall performance this season has been disappointing given their offseason acquisitions. Meanwhile, the Rays continue to exceed expectations and just completed a successful 5-1 homestand. With Shane Baz on the mound and Boston’s inconsistency, I see several angles worth targeting in tonight’s contest.

Quick Picks:
Best Bet: Tampa Bay Rays Moneyline (+120) ★★★★☆
Top Prop: Jose Caballero Over 0.5 Stolen Bases (+165) ★★★★☆
Value Play: Under 9 Runs (-110) ★★★☆☆

Moneyline +120 -140

Opening Line: Red Sox -135, Total 9

Sharp Money Analysis: Where Pro Bettors Are Placing Their Wagers

The line opened with Boston as a -135 favorite and has moved slightly to -140, indicating some public money on the home team following their series win against the Yankees. However, the lack of significant movement suggests sharp bettors aren’t rushing to back the Red Sox despite their momentum. The total has held steady at 9, which is interesting considering Fenway’s reputation as a hitter-friendly park and Boston’s offensive firepower. This stability indicates professional bettors see value in the under, likely due to the pitching matchup.

Pitching Matchup: Shane Baz vs Brayan Bello – Who Has the Edge?

Tampa Bay Rays: Shane Baz (5-3, 4.96 ERA)

  • Coming off three straight quality starts, lowering his ERA from 5.74 to 4.96
  • Has shown excellent command lately with a 28:6 K:BB ratio over his last four starts
  • Holding opponents to a .217 batting average over his last 25 innings
  • Has been much better on the road (3.88 ERA) than at home (6.15 ERA)

Boston Red Sox: Brayan Bello (2-1, 3.91 ERA)

  • Inconsistent since returning from injury in early May
  • Struggling with command, walking 14 batters in his last 25 innings
  • Allowing a concerning .287 batting average to right-handed hitters
  • Has pitched into the 6th inning just twice in his last five starts

Advantage: Tampa Bay. Baz has found his rhythm after early-season struggles, while Bello continues to battle command issues. Baz’s road excellence gives the Rays a significant edge in the starting pitching department.

Bullpen Breakdown

The Rays’ bullpen has been a strength all season, ranking 6th in MLB with a 3.42 ERA. Edwin Uceta’s impressive two-inning performance yesterday saved arms, and with Pete Fairbanks rested after pitching three straight days, Tampa Bay has their high-leverage relievers available. Kevin Kelly and Mason Montgomery each worked just one out yesterday, so they should be fresh.

Boston’s bullpen is more concerning, with Greg Weissert, Justin Wilson, and Aroldis Chapman all pitching in consecutive games against the Yankees. Manager Alex Cora mentioned his relief corps might be shorthanded tonight, which could force him to extend Bello even if he struggles early.

Key Betting Trends & Team Statistics That Matter

  • Tampa Bay is 14-4 in their last 18 games overall
  • The Rays are 6-1 in their last 7 games as an underdog
  • Boston is just 5-9 since Alex Bregman went on the injured list
  • The Red Sox are only 14-18 at Fenway Park this season (compared to 18-17 on the road)
  • Tampa Bay is 21-14 against right-handed starting pitchers
  • Under is 7-3 in the last 10 meetings between these teams at Fenway Park
  • Tampa Bay is 11-4 in their last 15 one-run games

Jose Caballero: Tampa Bay’s Secret Weapon on the Basepaths

Jose Caballero has been a revelation for Tampa Bay this season, especially on the basepaths. His stolen base yesterday gave him 21 for the season, tied for the AL lead. What makes tonight’s matchup particularly appealing for Caballero is Bello’s slow delivery to the plate (1.6-1.8 seconds) and Boston catcher Matt Thaiss’s below-average caught stealing percentage (21%, league average is 27%).

Caballero has attempted a steal in six of his last eight games when reaching base, and his fearless baserunning was on full display yesterday when he stole third base in the 8th inning of a tie game and scored the winning run. Against this battery, he should have multiple opportunities to run.

Fenway Park Factor: How the Venue Influences Today’s Game

Fenway Park traditionally favors hitters with its short left field wall, but there are factors working against an offensive explosion tonight:

  • Weather forecast calls for temperatures in the low 60s with 8-10 mph winds blowing in from center field
  • Night games at Fenway in June have averaged just 8.1 runs this season, below the park’s overall average
  • Shane Baz’s four-seam fastball and slider combination has been particularly effective in larger outfields, neutralizing the advantage that right-handed pull hitters typically enjoy at Fenway
  • The Rays have allowed 3 or fewer runs in 7 of their last 10 games, suggesting their pitching travels well

Expert Prediction & Best Bets for Rays-Red Sox Showdown

Primary Play: Tampa Bay Rays Moneyline (+120)

This price offers tremendous value on the hotter team with the more reliable starting pitcher. Baz has found his groove, while Bello continues to battle inconsistency. The Rays’ 14-4 record in their last 18 games shows they’re playing excellent baseball, and Boston’s 14-18 home record indicates they haven’t figured out how to consistently win at Fenway. With Boston’s bullpen potentially compromised after their Yankees series, I see the Rays winning this opener outright.

Strong Value Play: Jose Caballero Over 0.5 Stolen Bases (+165)

This is my favorite prop on the board. Caballero is one of the most aggressive baserunners in baseball, tied for the AL lead with 21 stolen bases. Bello is slow to the plate, and Thaiss has struggled to throw out runners. At +165, this prop offers exceptional value considering Caballero’s recent aggressiveness on the basepaths.

Worth Considering: Under 9 Runs (-110)

While Fenway typically favors hitters, tonight’s conditions (cooler temperatures, winds blowing in) and pitching matchup point toward a lower-scoring affair. Baz has been excellent recently, and the Rays’ bullpen has been shutting down opponents. The under is 7-3 in the last 10 meetings between these teams at Fenway, and I expect that trend to continue tonight.

Player Props Worth Targeting in Today’s Matchup

Player Prop Odds Rating
Jose Caballero Over 0.5 Stolen Bases +165 ★★★★☆
Shane Baz Over 6.5 Strikeouts -115 ★★★★☆
Yandy Diaz Over 1.5 Total Bases +130 ★★★☆☆
Brayan Bello Under 5.5 Strikeouts -125 ★★★☆☆

Final Thoughts: Rays Continue Their Winning Ways

The Red Sox may have momentum from their Yankees series, but the Rays are the more complete team right now. With Shane Baz finding his groove, Tampa Bay’s bullpen rested, and Boston potentially shorthanded in relief, the conditions are perfect for an upset. The Rays have been excellent as underdogs (6-1 in their last 7), and I expect that trend to continue tonight at Fenway. Look for a tight, lower-scoring game with Tampa Bay prevailing by a score of 5-3.

Score Prediction: Tampa Bay Rays 5, Boston Red Sox 3
