The Tampa Bay Rays (29-15) look to take the series as home favorites against the underdog Miami Marlins (21-25) as they continue their series at Tropicana Field. First pitch is scheduled for 12:15 PM ET on May 17, 2026. You can watch the action unfold on NBCSN and Peacock.

The Marlins aim to carry momentum from yesterday’s 10-5 upset victory over the Rays. Their offense exploded for 15 hits in that contest, highlighted by a Heriberto Hernandez home run. Miami scored a truly preposterous eight runs in the 10th inning to fuel the win. Despite the defeat, the Rays’ lineup showed life with 10 hits of its own. Junior Caminero drove in two runs.

Marlins vs Rays Picks & Predictions

• Rays Moneyline (-155, Fanatics)

The Rays hold a 16-4 record (.800 win percentage) as a favorite this season and are 4-1 (.800) when favored over their last 10 games. Conversely, the Marlins have struggled to overcome the odds, posting a 5-13 record (.278 win percentage) when playing as the underdog this year. The division-leading Rays are second in 2026 AL Playoff odds, only behind the Yankees.

Drew Rasmussen brings a stellar 3.16 ERA and an elite 0.91 WHIP over 42.2 innings into today’s start, consistently keeping traffic off the basepaths. Conversely, Perez has struggled to limit damage, posting a 4.94 ERA and a bloated 1.37 WHIP across 47.1 innings. The starting pitching disparity extends to the team level. The Rays’ rotation boasts a collective 2.93 ERA, easily outpacing the 4.76 ERA compiled by the Marlins’ starters.

• Under 7.5 (-124, FanDuel)

The Rays’ pitching staff holds opponents to a mere .222 batting average. Furthermore, overall lineup metrics for the Marlins (.246 AVG, .698 OPS) suggest they will struggle to replicate yesterday’s 10-run outburst against Rasmussen’s pristine command.

Pitching Matchup: Eury Perez vs Drew Rasmussen

The pitching matchup heavily favors the Rays on paper. Rasmussen has thrived on run prevention while Perez has battled consistency and command issues.

Rasmussen has been a model of efficiency, entering this contest with a 3-1 record. Where he truly separates himself is his elite command. He boasts an outstanding 0.91 WHIP and an exceptionally low walk rate of 1.48 BB/9. By stifling opposing lineups to a meager .198 batting average, he continually forces teams to string together multiple difficult hits to manufacture runs. With a healthy 9.07 K/9 rate, he possesses enough swing-and-miss stuff to escape any jams his occasional mistakes might create. Rasmussen has a 66th-percentile chase rate.

On the visiting side, Perez brings tantalizing pure stuff to the mound but has struggled to find consistency. His primary weapon is his ability to generate strikeouts, as evidenced by his impressive 10.08 K/9 mark. However, that high strikeout upside comes at a steep cost when it comes to free passes. Perez is currently walking batters at a concerning 4.56 BB/9 clip, which has directly contributed to his inflated 1.37 WHIP. Facing a patient Rays lineup, Perez will need to tighten his control to keep the Marlins competitive.

Team Stats Comparison

When sizing up this matchup, comparing season-long performance metrics reveals exactly why the Rays are comfortably positioned as favorites.

(Note: Offensive and Stolen Base metrics reflect the Marlins’ Away stats and Rays’ Home stats. Bracketed rankings are relative to all 30 MLB teams in those specific splits.)

The most glaring mismatch is the disparity in overall team success and run prevention. The Rays hold the second-best winning percentage in baseball (.659), fueled heavily by a top-tier pitching staff. Going up against a Marlins team that ranks 19th in both overall win percentage and runs allowed (4.52), the run-prevention edge leans heavily toward the home dugout.

At the plate, the Rays continue to demonstrate comfort at Tropicana Field. Their .264 home batting average ranks fifth in the majors, creating a stark contrast to a Marlins lineup hitting just .233 on the road. Neither team relies on overwhelming power to generate offense, instead manufacturing runs with elite speed. Ultimately, the Rays’ reliable contact hitting and elite pitching should neutralize the Marlins’ aggressive baserunning.

Best Player Prop Bets

• Junior Caminero Over 1.5 Total Bases (+115, BetMGM)

Caminero has a sturdy presence in 2026. In his last 30 games, he is slugging .517 with nine home runs and 31 total hits. Last night, he picked up two hits and two RBI in the loss. I like him to either blast an extra-base hit or pick up two singles today.

• Drew Rasmusssen Over 5 Strikeouts (-137, PrizePicks)

Rasmussen has been a reliable strikeout pitcher this year, tallying 43 in 42.2 innings pitched. While he won’t be confused with Nolan Ryan, Rasmussen has at least five strikeouts in six of eight starts this season, including each of his last four outings.

Marlins vs Rays Odds

The Rays remain a solid home favorite on the moneyline at -160, reflecting their dominant overall record and elite starting pitching advantage. However, the -1.5 runline presents a tempting plus-money payout (+140) for bettors willing to back them to win by multiple runs. The Marlins are heavily juiced at -165 to keep the contest within a single run.

The total opened at 7.5 but has since been bet down to an even 7. The spread itself has held steady since opening at 1.5, though the juice has shifted slightly to make laying the runs with the Rays a more lucrative proposition. I have noticed a similar narrative unfold on the moneyline, with oddsmakers adjusting the price down from the opening mark of -165 to the current -160.

Marlins vs Rays Public Betting Splits

Analyzing where the MLB public betting splits are landing can provide valuable context before placing your wagers. For this afternoon’s showdown, the betting handle reveals an overwhelming consensus among the betting public.

The betting action on the moneyline heavily favors the home team. The Rays are commanding a massive 84.3% of the betting tickets and an even more significant 86.0% of the total stake. Conversely, the underdog Marlins are drawing just 15.7% of the tickets and a meager 14.1% of the money. In this case, the heavy cash handle perfectly aligns with the ticket volume, showing unified confidence in the favorites.

The betting splits for the Over/Under present an interesting dynamic. The public is hammering the Over, which has garnered 77.2% of the tickets and an overwhelming 82.0% of the money. Those backing a lower-scoring affair are in the vast minority, with the Under seeing just 22.8% of the betting slips.

Despite 82.0% of the money banking on an offensive outburst, my prediction favors the Under. Given Rasmussen’s pristine 0.91 WHIP and the stingy home run prevention from the Rays, I am comfortable taking a contrarian stance against the heavy financial support for the Over.

Marlins vs Rays Injury Report

The injury report reveals a massive strain on the pitching staff for the Rays. With seven different pitchers sidelined, their bullpen is incredibly thin. This places immense pressure on today’s starter to pitch deep into the game and protect the remaining relief arms.

The Marlins are also dealing with their own pitching woes, missing starters Robby Snelling and Adam Mazur, alongside reliever Ronny Henriquez. With Perez struggling with command and run prevention this season, an early exit from him could expose a bullpen that is already missing key pieces.
