Guardians vs. Red Sox Prediction Markets
Cleveland enters Wednesday at 81-75 with a one-game AL Central lead over Chicago at 80-76. The White Sox hold the season-series tiebreaker, so the Guardians have little room for mistakes.
Foster Griffin starts for Cleveland at 15-5 with a 3.67 ERA. Boston counters with Sonny Gray, who's 17-5 with a 2.82 ERA. The Red Sox clinched their playoff spot on September 20 and are locked into the No. 5 seed.
Cleveland also sits three games clear of Texas, which is 78-78, in the race for the American League's No. 2 seed and a first-round bye.

Guardians vs. Red Sox Pick
Action Network Pick: Guardians to win at 50¢ or lower
Cleveland is the side I prefer if the contract opens around an even price. Griffin has been steady enough to keep the pitching matchup competitive, while the Guardians still have both the AL Central and postseason positioning to play for.
Gray gives Boston the stronger starting-pitching case on paper, so I wouldn't chase Cleveland if the contract moves too far above 50 cents. At an even price or better, though, the Guardians are my preferred side.

How a ProphetX Trade Works
ProphetX operates as a peer-to-peer exchange, with contracts trading between 1 cent and 99 cents. A winning contract on prediction markets settles at $1 and a losing contract at $0.
For example, 100 contracts priced at 60 cents cost $60 and return $100 if the outcome hits.
Place a qualifying $50 trade on any live contract with the prediction market app, and ProphetX adds $75 in bonus trading credit once that first trade settles.
