Giants Set Lineup as Tyler Mahle Makes Spring Training Debut vs. Athletics

More than a year later, it’s still odd to see the San Francisco Giants play the Athletics as opposed to the Oakland Athletics.

On Saturday, the Giants will head to Mesa, Ariz., to take on the Athletics as San Francisco seeks a second straight win.

San Francisco blew out the Los Angeles Dodgers on Friday, 12-2, as the Giants won their first spring training matchup with their long-time rival, dating back to their days in New York City and Brooklyn, respectively.

First pitch is set for 1:05 p.m. mountain and 12:05 p.m. pacific.

Here is a breakdown of today’s game, including the starting pitcher, lineup, injuries and other notes.

Giants Starting Pitcher

Tyler Mahle: 0-0, 0.00 ERA

Mahle, who signed a one-year deal with the Giants in the offseason, will make his first start of spring training. He spent the past two seasons with the Texas Rangers as he recovered from Tommy John surgery. He’s fully recovered and had a solid three months with the Rangers last season, but missed half the season with a shoulder issue.

INF Rafael Devers: He was scratched from Friday’s game with a tight hamstring.

OF Harrison Bader: He left Friday’s game with a right thumb contusion.

RHP Joel Peguero: His left hamstring tightness is progressing, and he should be able to begin a throwing program in the next week.

LHP Sam Hentges: The Giants signed him knowing he missed all of 2025 with right knee surgery and would need a slower ramp-up in spring training.

RHP Jason Foley: San Francisco signed the former Tigers closer with the idea that he would be ready at midseason after anterior capsule surgery in his right shoulder. He is on the 60-day injured list.

RHP Rowan Wick: Signed earlier this month, he’ll miss the 2026 season after Tommy John surgery and is on the 60-day injured list.

RHP Randy Rodríguez: He suffered an elbow injury late last season and had Tommy John surgery. He is expected to miss the season and is on the 60-day injured list.
