Yankees vs. Phillies — Polymarket Market Analysis (7:20 p.m. ET, NBC, Citizens Bank Park)
Sunday's series finale sends Weathers (3-7, 4.40 ERA) to the mound against Sanchez for the Phillies. Weathers has been inconsistent across the second half and faces a Philadelphia lineup anchored by home run leader Kyle Schwarber at Citizens Bank Park — one of the most run-friendly environments in the National League. Sanchez gives the Phillies a contact-suppression edge in a ballpark that rewards groundball-oriented pitching, and the home-field advantage gives Philadelphia the structural lean heading into first pitch.
