Alonso heads to the Phillies with Whitley going to San Francisco, Castillo also dealt
In a stunning move just one day prior to Opening Day 2025, the World Series Champion SF Giants and Philadelphia Phillies have struck a blockbuster move with very big names swapping uniforms.
The Giants send 2021 MVP and 4x All-Star 1B Pete Alonso, two-time World Champion SP Luis Castillo and $8.5 Million in cash to Philadelphia for SP Forrest Whitley.
Alonso was put on the block recently by GM Harris after it was made known that phenom 1B Andrew Vaughn had one the 1B job coming out of Spring Training. With still 4 years and $92.5 Million left on the 30 year old’s contract, this is a bold move for sure. The Phillies however did feel they had a hole at 1B coming out of Spring and when the opportunity arose to bring in a hitter that had once decimated the Phils in his years with the Mets, GM Brian Mason jumped at the opportunity.
Castillo, now 32 years of age, is in his final year of his contract and has been mostly used as a reliever for the Giants in his two season in San Francisco. Castillo will slot right into the rotation for the Phils and still looks to have outstanding stuff but a long term extension is still a question mark moving forward due to his age and asking price.
After winning the World Series last season, the Giants chose not to rest on the laurels this offseason and bringing in the 27 year old Whitley is proof of that. A mainstay for the Phils when the traded for him back in 2020, Whitley never truly reached his lofty potential as was hoped but he has many years ahead of him to do so. His best season came back in 2022, going 13-7 with just a 3.12 ERA. Currently on the DL with an elbow strain that will likely keep him out roughly 6 weeks, Whitley is also less than a year removed from a torn rotator cuff injury that required over 5 months to heal. Despite the injury concerns, this is still one of the better young arms in the league and he is making just $10 mil this year and is still arbitration eligible in 2026. GM Harris will likely look to negotiate a long term extension to keep the power pitcher in the Bay Area for a long time to come.
A trade that looks to help both teams in 2025 and both squads hope for years to come. Who got the best of the deal? Only time will tell.
