Hello everyone! It’s Thursday, and the baseball world rolls along as we get ever closer to spring training.

In Mariners news…

• The Mariners made a rare 40-man roster move, claiming right-hander Hagen Danner off waivers from the Blue Jays.

Around the league…

• The Nats agreed to a one-year contract with infielder Amed Rosario.
• The Diamondbacks have acquired right-hander Grae Kessinger in a minor swap with the Astros.
• Marlins left-handed starter Braxton Garrett will miss the entire 2025 season after undergoing elbow surgery.
