Seattle Mariners Headlines

Mitch Garver officially won the backup catcher role today, making an immediate impact with a home run in the Mariners' 2-1 victory over the White Sox. Bryan Woo also shone on the mound, needing just 73 pitches to complete six innings while striking out four and walking none, a promising sign as he gears up for the regular season. With Garver's addition, Andrew Knizner's future with the team is uncertain, and the Mariners are left to ponder other roster decisions, including the fates of J.P. Crawford and Bryce Miller. Meanwhile, Cal Raleigh is shaking off his World Baseball Classic fatigue, embracing the mantra of 'motion is lotion' as he pushes through the final days of spring training. The excitement surrounding the Mariners is palpable, but with high expectations comes the familiar anxiety of what could go wrong.
