Jerry Dipoto has had his share of hits during his time as the Mariners GM and VP of baseball operations, but he also has had some misses in his time in Seattle. This article will discuss how the Mariners let go of players before they became stars or solid contributors with their new clubs. Think of if the Mariners gave up too soon on Cal Raleigh, would he have ever been the guy to help the M’s end the drought? What about if the Mariners decided to trade George Kirby at the 2021 trade deadline for Jose Berrios, it would have been disastrous. You just never know what will become of a top prospect. Which is why it is still concerning to think what may become of Jake Fraley, Justin Dunn, Brandon Williamson, and Connor Phillips (for Jesse Winker and Eugenio Suarez) or Levi Stoudt, Edwin Arroyo, Noelvi Marte, and Andrew Moore (for Luis Castillo). Who knows what will become of these players and prospects the Mariners gave to the Reds in these deals. However, only third baseman Noelvi Marte at 26th and shortstop Edwin Arroyo at 38th are on the MLB.com top 100 prospects list. Hopefully, none of these players comes back to bite the Mariners later after the Mariners gave up on them, but if there were to be a player to do it expect them to be a future Red. Since we cannot predict the future, here are three players the Mariners gave up on in the Jerry Dipoto era fans wish he would have hung onto.
