(AP) — Yusei Kikuchi is about to begin his third season in the majors pitching for the Seattle Mariners and it's going to be the most important one because of the structure of his contract. Kikuchi could be with Seattle through the 2025 season if the team picks up his option after this season. That would guarantee him a huge pay day. But Kikuchi knows he must prove he's worth it for the Mariners to commit that kind of money and a spot in the rotation moving forward.
