Left-hander Ian Seymour gets the ball for Tampa Bay, squaring off against Boston's Patrick Sandoval in a pitching duel that gives the Rays a real opportunity to steal one in one of baseball's most storied venues.

Starting Pitchers: Ian Seymour vs. Patrick Sandoval

Ian Seymour draws the assignment at Fenway, and this is a significant moment for the young left-hander. Seymour has been working his way through the Rays system and any regular-season start at a ballpark like Fenway Park is a measuring stick. The Green Monster in left field plays unique mind games with left-handed pitchers — Seymour will need to command his pitches and keep hitters off balance to navigate that lineup successfully.

On the other side, Patrick Sandoval takes the hill for Boston. Sandoval is a crafty left-hander in his own right, and the Red Sox will lean on him to control a Rays lineup that will need to come ready with a plan against another southpaw. Rays hitters should look for opportunities early in counts and not let Sandoval settle into a rhythm.

Boston Red Sox Lineup to Watch

Boston is sending out a lineup that mixes versatility with some interesting positional decisions. Anthony Seigler leads off and is deployed at second base, an unconventional choice that speaks to the Red Sox roster flexibility this season. Ceddanne Rafaela bats second and patrols center field — he's a dynamic, high-energy presence at the top of the order who can beat you with his legs and his glove as much as his bat.

Wilyer Abreu slots in at three in right field, followed by Willson Contreras — now playing first base for Boston — hitting cleanup. Contreras is the middle-of-the-order threat Seymour will need to navigate carefully. Romy Gonzalez handles the DH role at five, with Caleb Durbin at third, Andruw Monasterio at short, Jahmai Jones in left, and Carlos Narváez catching and batting ninth.

Keys to Watch for the Rays

• Seymour's command: Fenway punishes mistakes. If Seymour can locate his fastball and work his offspeed pitches down in the zone, he can keep this Boston lineup from doing damage.
• Handling Rafaela: Ceddanne Rafaela is dangerous on the bases and in the field. Keeping him off the bases early is critical — letting him reach and run creates problems that compound quickly.
• Contreras in the cleanup spot: Willson Contreras is a proven run-producer. Seymour cannot afford to let him beat him with runners on base.
• Rays lineup production: With the Rays lineup not yet confirmed, Tampa Bay's offense will need to show up against Sandoval and take advantage of any mistake pitches early.

Prediction

This is a winnable game for Tampa Bay. Seymour has the stuff to compete at Fenway, and the Rays have shown this season they can manufacture runs and play sound baseball on the road. Boston's lineup is capable but not without holes, and if Seymour keeps the ball in the park and the Rays bullpen holds up, expect a close, low-scoring game. Call it a 4-3 Rays victory in a game decided by the middle innings.
