The Philadelphia Phillies are trying to focus on this season’s success, but also maintain it for the future. Hence, it’s great news for them to see they landed a lefty over the Seattle Mariners.
Lefty Adam Seminaris signed with the Phillies. Now, the transaction was first reported on late November, however, it now appears that Seminaris could become a major league pitcher after his great output in Double-A.
The Mariners could definitely regret not making a bigger effort to keep the lefty’s services. The Phillies already assigned Seminaris to Triple-A Lehigh Valley. The club will break camp in late March and could possibly make his debut in the 2026 MLB season.
Seminaris is a very good prospect
Considered a solid left-handed pitcher, Seminaris could excel and be called up quickly. He has excellent pitchability, incredible control, and a great changeup. He is regarded as a possible back-end starter in the MLB.
He could improve his velocity, which is his biggest weakness. Seminaris is seen as a high-floor prospect. He also has AAA experience. In fact, he played for the Salt Lake Bees and the Nashville Sounds previously.
