Mariners vs Guardians MLB Betting Preview
The Mariners and Guardians will square off on Sunday afternoon in the last of a three-game set at Progressive Field in Cleveland.
I’m very excited for this pitching duel between Emerson Hancock and Gavin Williams.
Hancock is running a 3.60 ERA through 85 innings, while Williams has a 3.82 ERA across 96 frames.
Mariners vs Guardians Pick, Betting Analysis
That said, I’m even more bullish on these starters than the numbers suggest. Hancock has the stuff and command to be Seattle’s best pitcher, while Williams is ascending into Ace territory for a Cleveland staff that needs one.
I’ll take the NRFI.
