Tyler Phillips gets the ball for Miami, squaring off against Nick Pivetta in a late-season regular season matchup that carries real weight as September winds down. Fans back home can catch the action on Marlins.TV or tune in on 560AM WQAM or 710 WAQI in Spanish.

Pitching Matchup: Tyler Phillips vs. Nick Pivetta

Tyler Phillips takes the mound for the Marlins in what is a significant late-season start. Phillips has had stretches this year where he has shown the ability to work deep into games and keep Miami competitive, and that is exactly what this road trip demands. A quality start from Phillips would go a long way toward setting the tone for the Marlins offense to do its work.

On the other side, Nick Pivetta brings veteran experience to the hill for San Diego. Pivetta is a pitcher capable of missing bats and working through a lineup multiple times, so Miami's hitters will need to be disciplined at the plate from the first inning. Getting deep counts early and forcing Pivetta to work could be the difference in this game.

San Diego Lineup Phillips Must Navigate

The Padres are rolling out a formidable lineup that Phillips cannot afford to take lightly at the top. Fernando Tatis Jr. leads off from second base, followed by Dustin Harris in right field. Manny Machado slots in third as the designated hitter, with Ty France hitting cleanup at first base. Jackson Merrill handles center field in the five spot, Xander Bogaerts is at shortstop batting sixth, and Jake Cronenworth rounds out the middle of the order at third base. Samad Taylor and catching prospect Ethan Salas close out the lineup.

That is a lineup with legitimate threats one through six. Phillips will need his secondary offerings working to keep Tatis, Machado, and France from doing damage in big spots.

Keys to Watch for Miami

• Phillips's command: Walks against this Padres lineup get amplified fast. Phillips needs to pound the zone and work efficiently through the order.
• Handling Tatis and Machado: The Padres' one-two-three punch at the top is where games can unravel. Getting through those at-bats without damage is priority one.
• Road discipline at the plate: Petco Park is a pitchers' ballpark. The Marlins offense needs to be patient against Pivetta and manufacture runs where possible rather than waiting for a big inning.
• Bullpen availability: If Phillips goes five or six innings, Miami's relief corps needs to be sharp and ready to protect any lead into the late innings.

Prediction

This is a tough road draw. The Padres lineup is deep, Petco Park suppresses offense, and Pivetta is a capable arm. That said, if Phillips can give Miami five solid innings and the offense strings together a couple of productive frames against Pivetta early, the Marlins are absolutely in this game. It figures to be a low-scoring affair decided by pitching and a handful of key at-bats. Expect a close game. Marlins 3, Padres 2.
