The Seattle Mariners (49-45) and Detroit Tigers (59-31) wrap up their three-game series at Comerica Park on Sunday afternoon with what promises to be an intriguing pitching matchup. After Detroit has dominated the first two games of the series, scoring 27 runs combined, I’m seeing value on the visiting Mariners as they send their talented right-hander Logan Gilbert to the mound against Jack Flaherty. While Detroit has been MLB’s best team record-wise, this pitching matchup presents a solid opportunity for Seattle to salvage the finale and pick up a crucial win before the All-Star break.
Quick Picks:

Sharp Money Analysis: Where Pro Bettors Are Placing Their Wagers
Despite the Tigers’ dominance in the first two games of this series, we’re seeing the line move slightly in Seattle’s direction, opening at -120 and now sitting around -125. This suggests sharp money believes the Mariners have a better chance than the general public might think after watching Detroit’s offensive explosion in the first two games. The total has held steady at 8, which feels right given the starting pitching matchup features two capable arms who could limit the recent offensive fireworks.
Pitching Matchup: Logan Gilbert vs Jack Flaherty – Who Has the Edge?
Seattle Mariners: Logan Gilbert (2-3, 3.72 ERA)
- Gilbert has been significantly better than his record indicates, posting solid peripheral numbers
- Outstanding 79 strikeouts to just 13 walks in 55.2 innings (5.3 K/BB ratio)
- Elite 1.01 WHIP shows his dominance and ability to limit baserunners
- Has allowed 3 or fewer earned runs in 8 of his last 10 starts
Detroit Tigers: Jack Flaherty (5-9, 4.70 ERA)
- Flaherty has struggled with consistency despite impressive strikeout numbers (117 Ks in 95.2 IP)
- Control issues have plagued him with 38 walks, leading to a 1.24 WHIP
- Has allowed 4+ earned runs in 6 of his last 10 starts
- Opponents are hitting .252 against him this season
Advantage: Seattle. Gilbert’s precision and ability to limit damage gives the Mariners a clear edge in the starting pitching department.
Bullpen Breakdown
The Mariners’ bullpen remains one of their strengths despite some recent struggles. All-Star closer Andres Munoz (21 saves, 1.54 ERA) anchors a unit that features solid arms in Matt Brash, Carlos Vargas, and Gabe Speier. The recent revelation that Munoz was tipping pitches against the Yankees explains his rare blown save and should be corrected for this outing.
Detroit’s bullpen has been effective but not dominant, with Will Vest (15 saves) and Tommy Kahnle (9 saves) sharing closer duties. The Tigers’ relievers have been heavily taxed during the first two games of this series, which could create an advantage for Seattle in a close game on Sunday.
Key Betting Trends & Team Statistics That Matter
- The Mariners are 26-21 on the road this season despite recent struggles
- Detroit is an MLB-best 59-31 and has been dominant at Comerica Park (32-14)
- Seattle is 18-10 when Logan Gilbert starts over the past two seasons
- The Tigers have scored 27 runs in the first two games of this series
- Detroit ranks 8th in MLB in runs per game (4.98) while Seattle ranks 15th (4.66)
- The Mariners have gone 5-2 in Gilbert’s last 7 road starts
- Detroit is 4-7 in Flaherty’s last 11 starts despite their excellent overall record
Cal Raleigh’s Historic Season: Seattle’s Power-Hitting Catcher Ready to Break Out
Cal Raleigh has been putting together a season for the record books, establishing himself as baseball’s premier power-hitting catcher. While he’s been relatively quiet in this series so far, Raleigh matches up well against Flaherty’s tendency to give up the long ball. With reports noting that Raleigh “puts up stats never before seen in MLB history,” his ability to change the game with one swing makes him a key factor in this matchup. Look for Raleigh to break out in the series finale against a pitcher who has struggled with consistency.
Comerica Park Factor: How the Venue Influences Today’s Game
Comerica Park has traditionally been known as a pitcher-friendly venue, but this season it’s playing slightly more favorable to hitters with a runs factor of 1.039. The spacious outfield dimensions can help prevent home runs (0.928 HR factor), but the park yields a good number of doubles and triples. Sunday’s forecast calls for mild temperatures around 75 degrees with minimal wind, which should create neutral conditions that won’t significantly favor either pitchers or hitters. Gilbert’s ability to induce weak contact should play well in Comerica’s dimensions, while Flaherty’s tendency to allow hard contact could be problematic even in a larger park.
Expert Prediction & Best Bets for Mariners-Tigers Showdown
Primary Play: Seattle Mariners Moneyline (-125)
I’m taking the Mariners on the moneyline for my top play. Logan Gilbert gives Seattle a clear advantage in starting pitching, and Detroit’s bullpen has been taxed heavily in the first two games of this series. While the Tigers have been dominant at home this season, Flaherty has been their weak link in the rotation with a 4.70 ERA. This is a perfect spot for Seattle to avoid the sweep before heading into the All-Star break. The price of -125 offers solid value given the pitching matchup.
Strong Value Play: Logan Gilbert Over 6.5 Strikeouts (+105)
Gilbert has been a strikeout machine this season with 79 Ks in just 55.2 innings, averaging nearly 13 strikeouts per 9 innings. The Tigers’ aggressive approach at the plate plays right into Gilbert’s strengths, as Detroit hitters have racked up the 7th most strikeouts in MLB. At plus money, this prop offers excellent value for a pitcher who has the stuff to rack up swings and misses.
Worth Considering: Under 8 Runs (-110)
After two high-scoring affairs, I expect the pitching to take center stage in the series finale. Gilbert has been excellent at limiting damage, and the Mariners’ offense has been inconsistent all season. While Detroit has exploded in the first two games, they’ll face a much tougher pitcher in Gilbert on Sunday. T-Mobile Park in Seattle has been baseball’s most pitcher-friendly venue this season, and the Mariners’ staff tends to carry those tendencies on the road. Look for a lower-scoring affair in the 4-3 range.

Final Thoughts: Mariners’ Pitching Advantage Should Prevail in Series Finale
While Detroit has been the better team this season and has dominated the first two games of this series, baseball is a game where the starting pitcher can completely change the equation each day. Logan Gilbert gives the Mariners a significant advantage on the mound, and I expect him to quiet Detroit’s hot bats. Seattle’s desperate need for a win before the break adds motivation, and Flaherty has been Detroit’s most vulnerable starter. Don’t be fooled by the first two games of this series – the pitching matchup sets up perfectly for the Mariners to salvage the finale.
Score Prediction: Mariners 4, Tigers 2
