It is certainly a fun time to be following the world of Mariners prospects. In addition to the performances we have below—including Cal Raleigh being all but literally ablaze—it’s the time of year many sites update their lists of top prospects and the Mariners fare quite well.
On Baseball Prospectus’ updated Top 50 Prospects, the Mariners land three in Jarred Kelenic (13), Julio Rodriguez (39) and Logan Gilbert (42). If you think that #13 rating is high for Kelenic—ESPN’s Keith Law has him all the way up at the eighth-best prospect in the game, with Julio Rodríguez checking in at #49 on that list.
