Tigers vs Mariners MLB Betting Preview
Tigers vs Mariners Pick, Betting Analysis
In his last four starts, Framber Valdez has twice completed seven innings with two runs or less. He’s totaled 15 strikeouts and two walks in those starts and one of them was his last time out in Sacramento.
However, in between those two starts, he allowed nine runs (eight earned) over just 5.2 innings with as many walks (five) as strikeouts. Prior to those four starts he allowed five and four runs.
Valdez has been one of many underperforming Tigers on the year with all non-pitching estimators below his 4.41 ERA, but still above four, along with a career worst 4.48 Bot ERA, the third season in a row that PB hasn’t graded any pitch other than his curveball above average.
Aside from the park upgrade that T-Mobile offers every visiting pitcher, Valdez also gets the benefit of facing a poor offensive unit against LHP and one I don’t think Taylor Ward is going to solve that particular problem on his own.
Even with him in the projected lineup, they still average just a 93 wRC+ against southpaws and will probably be starting several LHBs against Valdez, which is interesting because same-handed batters have a .301 wOBA, but just a .260 xwOBA against Valdez this year, likely the source of most of the gap between his ERA and estimators with RHBs 10 points above their actual results against him.
Despite their poor team defensive numbers (-17 Runs Prevented), the Tigers have jettisoned the worst of their defenders, aside from Spencer Torkelson (-9 FRV), with the projected defense at 6 FRV, led by Dillon Dingler’s 10 (he really should get some MVP votes).
Both bullpens average the same 3.87 on their FIP, xFIP and SIERA over the last 30 days and despite neither doing much to those units at the deadline (I don’t know if you can count Seranthony Dominguez as much of an upgrade for the Mariners), BARTOLO ranks Seattle the 4th best unit in the game, well above Detroit’s 23rd ranked unit with more than half a run gap between their weighted FIPs.
Continuing to go backwards here, the Seattle defense has also been one of the worst units in the league this year (-27 Runs Prevented), but haven’t been able to remove their worst offenders, at least against LHP, with Thursday’s projected lineup having accumulated -17 FRV (assuming Mitch Garver -5 FRV catches the day game after a night game with Cal Raleigh at DH).
Also, aside from Max Clark’s hot start (216 wRC+ vs. RHP), the top four in Detroit’s recent standard lineup against righties all have at least a 145 wRC+ this season with none of the projected nine below 86. This lineup even averages a 142 wRC+ over the last 30 days.
Lastly, Bryce Miller has a 2.80 ERA and while many of his faults can be masked by the park, for the most part that hasn’t been the case… until recently.
Through his first eight starts (plus one piggyback outing), he posted a 30.5 K-BB% with a 96.4 mph fastball, allowing just a 27.5 HardHit%.
However, over his last four outings, those numbers have become a 4.1 K-BB%, 95.3 mph fastball and 38.2 HardHit%. Now I'm questioning if he's still healthy.
Valdez's recent volatility seems better than Miller's downward spiral, while the Detroit offense is far better against RHP than Seattle is against LHP. Add in a defensive edge and a small base running edge (4 BRR) for the road team and even with the bullpens a potential source of debate, I still make the Tigers favorites here.
Pick: Tigers ML (+116, 1u | Bet to -110)
