Key Players & Pitching Matchups

- Janson Junk & Sandy Alcantara (Marlins): Miami relies on pitch efficiency and command to handle Philadelphia’s power bats. After starting Junk in the opener, Miami needs length from its starters to preserve the bullpen.

Power vs. Speed Dynamic
- Philadelphia’s Slugging: Kyle Schwarber and Bryce Harper drive Philadelphia’s extra-base scoring, taking full advantage of the short porch at Citizens Bank Park.

Bullpen Form
Over their last 10 games, Miami’s pitching staff holds a 3.07 ERA, compared to 3.68 ERA for Philadelphia. Late-inning bullpen execution will decide close finishes, as Miami has repeatedly mounted late comebacks against Philadelphia’s relief corps this season.
