Miami Marlins vs Philadelphia Phillies Prediction, Odds and Picks for Today, 09/23/25

The Marlins aren’t mathematically eliminated from playoff contention yet thanks to a 6-game win steak and wins in 10 of their last 11 games. However, the recent hot streak might be too little too late for the Fish. Miami is still 4 games back of a wild card spot with 6 games to go against the Phillies and Mets. Tuesday’s series opener against the Phillies presents a tough matchup for the Marlins, who will be playing their seventh straight road game. They’ve won the first 6 against the Rockies and Rangers, but going up against Philadelphia’s Cristopher Sanchez presents a tough challenge.

Sanchez has emerged as a star in 2025. He enters this matchup with a strong 2.66 ERA and 1.10 EHIP through 30 starts and 189.1 innings of work. The 28-year-old left-hander is coming off an outing in which he allowed 4 earned runs on 7 hits through 7 innings against the Dodgers. This could be a good spot to bounce back before gearing up for a postseason run. Sanchez faced the Marlins a few weeks ago on September 5 and tossed 7 innings of 1-run ball. That should give him plenty of confidence for this one. Back Sanchez and the Phillies at home.
