Sean Zerillo’s Giants vs Marlins Preview
Giants starting pitcher Kyle Harrison is typically better at home than he is on the road, as he allows a ton of fly balls that tend to stay in at Oracle Park (0.95 HR/9 allowed at home) but leave the park anywhere else (2.07 HR/9 allowed on the road).
That said, LoanDepot is another park that suppresses home runs (92 HR Factor over the past three seasons), so this is not a bad park fit for Harrison.
The most significant part of this handicap is San Francisco’s bullpen. The Giants arguably have MLB’s best bullpen. Randy Rodriguez has been my favorite reliever to watch this season. They moved Camilio Doval back into the closer’s role and Ryan Walker back into the set-up role. This unit leads all bullpens in ERA (2.48) and Stuff+ (107).
San Francisco’s lineup is also struggling, posting an 80 wRC+ over the past two weeks and a 93 wRC+ over the past month.
The Giants were OK at the plate in April. Still, they never graded out as anything better than a borderline bottom-10 lineup, and they’ve essentially sustained that level of performance while regressing in some areas.
Hopefully, we’ll see plenty of good pitching from the Giants' side. I’m scared of backing Miami starter Cal Quantrill, but I still only project 7.9 runs for this ballgame.
Pick: Under 8.5 (-102, BetMGM | Play to 8 +100)
