Marlins Hold the Team Pitching Edge
Miami owns the better team pitching numbers overall with a 3.92 ERA and 1.24 WHIP compared with Philadelphia's 4.16 ERA and 1.31 WHIP, but this individual matchup heavily favors Sanchez given his profile against a lineup that still has to solve him directly.
Philadelphia

On the injury front, first baseman Kyle Stowers remains on the 10-day IL, while relievers Anthony Bender and Andrew Nardi and starter Max Meyer are also sidelined, reducing the club's pitching depth.
