The Seattle Mariners are -140 favorites to win their third consecutive game tonight.
However, with the Detroit Tigers in much better form at the plate, my Tigers vs. Mariners predictions see plenty of value in backing the underdogs.
Let's dive deeper into my MLB picks for Tuesday, August 4.
Who will win Tigers vs Mariners today: Tigers moneyline (+115)
Troy Melton has pitched well while having batted-ball luck further boost his numbers.
That will shift at some point, but I’m not sure regression will come knocking against the Seattle Mariners. They've hit just .215 and slot 28th in wOBA against right-handed pitching over the last month.
Emerson Hancock’s xFIP is nearly two runs higher than his ERA in the last 30 days. His numbers are more likely to go south in this matchup as the Detroit Tigers rank Top 5 in average, wOBA, and OPS during the same period.
Back the Tigers to +100.
COVERS INTEL: Seattle's 27th ranked scoring offense will have a hard time producing against Melton, who ranks in the 90th percentile in Pitcher Run Value.
Tigers vs Mariners Over/Under pick: Under 8 (-120)
The Mariners are not hitting for average or power, and they own the third-highest soft contact rate over the past month.
Melton’s expected stats (80th percentile in xERA, 73rd in barrel rate) are strong and should serve him well in this matchup.
Hancock is exceptional at avoiding walks, and limiting free baserunners is important against an in-form Tigers attack.
Seattle’s bullpen sits third in xFIP over the last month and should help put the clamps down in the back portion of this game.
I make -129 the fair price and see value on the Under.
- ML/RL bets: 69-62, -7.10 units
