New York Yankees vs. Boston Red Sox

Platform comparison

Market context

The upcoming MLB contest at Fenway Park pits the New York Yankees (48-34) against the Boston Red Sox (35-46) on Sunday, 28 June, with the Red Sox having swept the previous three meetings in this series. This 50-50 crowd-implied probability mirrors historical patterns where a team with superior season records faces a hot opponent in a short series; the Yankees remain dangerous due to their 3.34 ERA and 121 home runs, yet the Red Sox have surged with 12 home runs and a .427 slugging average over their last ten games[1][7].

Traders must monitor the return of Giancarlo Stanton, listed on the 10-Day IL with an estimated return of 29 June, which could significantly alter the Yankees' offensive output if he joins the lineup for this game[3]. The Red Sox are bolstered by Caleb Durbin, who leads the team with three home runs and a .457 batting average in the last ten outings, while Yankees starter Carlos Rodon (4-2, 3.70 ERA) faces Sonny Gray, who holds a 2.51 ERA over his last five starts[1][2]. Any delay in Stanton's return or a sudden shift in the starting pitchers' availability will be the primary catalyst moving the line before the 7:20 p.m. ET start.

What's the difference between match odds and outright odds?

Match odds cover a single game ("Bayern beats BVB"). Outright odds are long-term aggregates ("Bayern wins the league"). Outright markets have deeper liquidity; match markets have faster resolution.

Can I import form data and lineups?

This page shows the live Polymarket quote as an implied probability. Form data and lineups must be researched separately via sports data providers (e.g. Soccerway, ESPN, FBref) — we surface the market probability, not the sport analysis.
