Mariners Moose Tracks, 4/17/24: Jack Leiter, Andy Pages, and Forrest Whitley

Good morning everyone! Let’s dive into the latest.

In Mariners news...

  • Jonatan Clase made history in his debut game.

Jonatan Clase: first player with RBI in his @MLB debut while wearing #42 since Marc Sagmoen on April 15, 1997. The crazy part? That was the 50th anniversary of Jackie Robinson’s debut/EXACT day MLB retired #42 throughout baseball. Sagmoen changed to #37 the next day. #TheMayerGWS
