The Tampa Bay Rays (66-66) and Seattle Mariners (67-66) meet for the finale of a 3-game series Wednesday. First pitch from T-Mobile Park is set for 4:10 p.m. ET. Let’s analyze FanDuel Sportsbook’s lines around the Rays vs. Mariners odds and make our expert MLB picks and predictions for the best bets.

Season series: Tampa Bay leads 3-2

Tampa escaped with a 3-2 win over Seattle Tuesday while covering as a +149 road underdog. The Rays scored 3 runs in the 7th and 8th innings to come back from down 1-0 and survive a late push by the Mariners. 1B Yandy Diaz went 2-of-4 at the plate and hit the HR to take the lead in the 8th.

The win ended a streak of back-to-back losses for Tampa while simultaneously ending a streak of back-to-back wins for the Mariners.

Rays at Mariners picks and predictions

Prediction

Rays 5, Mariners 3

Moneyline

PASS.

I slightly lean toward the Rays to cover here as (+144) underdogs, but their odds are slightly safer on the run line.

Run line/Against the spread

BET RAYS +1.5 (-150).

Tampa Bay is the slightly hotter team entering this matchup, being 7-3 in its last 10 overall while the Mariners are 4-6 over that same span. The Rays are also 4-2 in their last 6 vs. Seattle.

Tampa has also been the much better ATS team, being 36-28 ATS on the road while the Mariners are only 28-40 ATS at home and 54-79 ATS overall.

Over/Under

LEAN OVER 7 (-110).

The Over is 5-3-2 in Seattle’s last 10 overall and is 5-3-2 in the last 10 meetings between these 2 squads. The Over is also 4-1-1 in Tampa’s last 6 wins vs. the Mariners.

In a matchup where the O/U has been even for both teams individually and in recent matchups between these squads, it is unlikely that the Under will hit for the 3rd-straight game.

This is a lean because the Under has hit in each of the last 2 Tampa-Seattle matchups and because the Under has hit in 3-straight for Tampa Bay.
