The Los Angeles Dodgers welcome the Seattle Mariners to town tonight, and they sit as a heavy -178 moneyline favorite for the series opener at Dodger Stadium.
Behind Justin Wrobleski, my Mariners vs Dodgers predictions expect L.A. to walk away with a victory here as it faces the vulnerable Luis Castillo.
Read more in my MLB picks for Tuesday, July 28.
Who will win Mariners vs Dodgers today: Dodgers -1.5 (+113)
Justin Wrobleski has been fantastic all season, and he’s dominating since the All-Star break. Across his last two outings, the Los Angeles Dodgers stud owns a 1.38 FIP while limiting opponents to a 35.3% hard-hit rate.
The Seattle Mariners have also struggled immensely against left-handed pitchers this season, compiling an 89 wRC+. That’s compared to a 104 wRC+ vs. right-handed hurlers.
As for Luis Castillo, he has surrendered 2.50 HR/9 over his previous three appearances while posting a 6.17 FIP.
With Wrobleski limiting a weaker split of Seattle’s offense and Castillo leaking power, Los Angeles has a clear path to creating separation.
I’ll play this to -110.
COVERS INTEL: Luis Castillo has been far less effective away from T-Mobile Park, posting a 5.05 road FIP compared to a 3.60 mark in Seattle. With the veteran also 1.80 HR/9 on the road compared to 0.81 at home, L.A. can capitalize.

Mariners vs Dodgers Over/Under pick: Under 9.5 (-113)
The Under looks like the better angle tonight. Aside from Seattle’s inconsistencies against lefties, the Mariners are also in poor offensive form, posting an 88 wRC+ over their last six games with just a .118 ISO.
The Dodgers bullpen hasn’t been amazing with a 4.35 xERA over the last week, but Seattle doesn’t pose much of a threat at the dish, even when Wrobleski exits.
As for L.A.’s offense, the Dodgers are right around league average at the moment with a 100 wRC+ across their previous five contests, while their ISO sits at just .176.
I expect them to score enough off Castillo, but the Mariners relief corps is holding its own, compiling a 3.20 FIP over the last two weeks.
With a relatively high total of 9.5, the Under is the best play.
I’ll play this to -130.
