By Sean Paul

I definitely want to fade Nats starter Mitchell Parker. However, laying -176 juice just isn’t worth recommending for me, but I think the Phillies will win, so feel free to take that if you don’t mind the juice.

I’m rolling with Philadelphia -1.5 at -110 and would play it to -125.

I think the Phillies cruise to an easy win on Sunday, as Parker allows 5+ runs again, while Aaron Nola gets on track in his first outing since coming back from the IL.

Pick: Phillies -1.5 (-110)

By Brit Devine

Erick Fedde is back on the mound for the Braves again, which means it’s time to bet against him.

Fedde has now given up at least three runs in nine of his last ten starts, while giving up all those runs in the first five innings in each occurrence.

The right-hander has also really struggled with lefties and should see at least seven of them in the Guardians lineup.

With his 2.5 earned runs line hovering at a price much worse than this one, it makes much more sense to attack him via the Guardians plating some runs while he is in the game.

Pick: F5 Guardians Over 2.5 Team Total (+100)

PRO projects Diamondbacks‘ starter Nabil Crismatt to get 3.31 strikeouts tonight, which represents a 15.3% edge against the market.

Fade him today and go with the under.

Evan Abrams’ Contrarian Unders for Winning Teams, Later in Series system targets unders in MLB series games (Game 2 or later) where both teams have winning records, suggesting quality pitching and competitive matchups.

However, public betting leans toward the over — likely expecting fireworks between top teams — which creates contrarian value on the under, which applies to the Padres vs. Dodgers game today.

By capitalizing on low public support for the under (≤35%), the strategy fades public perception in favor of market inefficiencies, especially when bettors overestimate offensive output late in a series.

This Road Tilt in the Dead Heat system targets MLB regular-season games where two evenly matched teams —based on win percentage— meet in a non-division setting, and one is quietly priced as a modest road favorite, such as the Seattle Mariners tonight.

When there’s no clear performance gap, but the market still tilts slightly toward the road team, it suggests underlying confidence from oddsmakers that may not be reflected in public perception.

This model seizes those subtle cues, leaning into a narrow value created by near-identical records and overlooked road strength.
