MLB Starting Pitcher Previews: March 30, 2025 - Cubs, Giants, A's Set Rotations

Cubs @ Diamondbacks: Matthew Boyd makes his anticipated Cubs debut. He faces Eduardo Rodriguez, who looks sharp this spring (2.70 ERA, 12 K, 2 BB in 10 IP) after an injury-plagued 2024.

Giants @ Reds: Robbie Ray brings his hot spring performance (3-0, 1.86 ERA, 23 K in 5 starts) to Cincinnati. He'll duel Nick Martinez, who has historically pitched well against the Giants (3.10 ERA, 34 K in 13 career games).

A's @ Mariners: The Athletics rely on workhorse JP Sears (32 starts in each of the last two seasons). He opposes Bryan Woo, making his season debut and his first appearance as part of the Mariners' Opening Day rotation.

Why this matters: Starting pitching often sets the tone for the game. Understanding these matchups helps fans anticipate game flow, potential outcomes, and key performances to watch.

Boyd's Cubs Debut vs. Rodriguez's Rebound (Cubs @ D-backs): All eyes will be on Matthew Boyd as he officially toes the rubber for the Chicago Cubs for the first time. Facing him is Arizona's Eduardo Rodriguez. After injuries hampered his 2024 season, Rodriguez is aiming to build on a promising spring training where he demonstrated good control and effectiveness. This matchup pits a pitcher debuting with a new team against one seeking a strong comeback season.

Ray's Hot Hand vs. Martinez's History (Giants @ Reds): The San Francisco Giants send Robbie Ray to the mound, who absolutely dominated during spring training, posting impressive stats across five starts. His performance suggests he's ready to lead the rotation. The Cincinnati Reds counter with Nick Martinez, who, while not having Ray's spring numbers, has a track record of success against the Giants organization specifically. This contrasts recent performance against historical success.

Sears' Durability vs. Woo's Opportunity (A's @ Mariners): Oakland's JP Sears has been a constant in their rotation, proving his durability by making 32 starts in consecutive seasons. He provides reliability for the A's. The Seattle Mariners give the ball to Bryan Woo, who earned his spot in the Opening Day rotation for the first time. This marks a significant opportunity for the young pitcher to establish himself early in the season.
