Big league rosters don't expand for a few days, but the prospect world is already abuzz with callup news -- specifically the promotion of Dylan Crews. MLB's No. 3 prospect made his Nationals debut on Monday night, going 0-for-3 with a walk.

On the latest MLB Pipeline Podcast, prospect gurus Jonathan Mayo and Sam Dykstra dig into the 2023 second-overall pick's first season in pro ball and provide analysis on Washington's decision to call him up.

Following the break down, the pair highlights Double-A Montgomery's prospect-laden roster. They welcome on Jack Sadighian, the broadcaster for the Rays' affiliate, and talk about the lineup, which features three Top 100 prospects -- Carson Williams (MLB No. 6), Xavier Isaac (MLB No. 21) and Brayden Taylor (MLB No. 50).

In the second half of the episode, Mayo and Dykstra put on their ranking caps and discuss the top 10 farm systems based on infield prospects. The episode ends with a debate of whether Kumar Rocker (TEX No. 2) should be a Top 100 prospect and a question from the mailbag about Rockies prospect Chase Dollander (MLB No. 23)
