The news the Mariners were calling up top prospect Jarred Kelenic, the No. 4 overall prospect in baseball, led to an obvious follow-up question: Who’s next?

The buzz of a top prospect getting called up can be intoxicating, so wanting to know who among the game’s best future stars might get their chance after Kelenic makes a lot of sense. Turns out, the Mariners created another headline by making right-hander Logan Gilbert, their No. 4 prospect (and No. 28 overall), the next guy up. He'll also make his debut Thursday, the same day Kelenic is slated to be in the lineup.

But as good as Gilbert has the chance to be, and trust that he might be very, very good, the question is really reserved to the very top of the prospect pyramid. It’s like when someone really barrels up the ball at the plate: It makes a different sound. When a top five prospect gets called up, it creates a different kind of buzz.

With Kelenic getting called up there is no doubt all eyes will now turn to the best prospect in all of baseball, Wander Franco. Yes, he’s just 20 and yes, he hadn’t played above Low-A ball entering the 2021 season. But the Rays really set these forces in motion by pushing the precocious hitter up to Triple-A to begin the year.
