PROSPECT: Spencer Arrighetti, SP, Houston Astros
ANALYSIS: The Astros selected Arrighetti in the sixth round of the 2021 draft out of Louisiana-Lafayette. He had journeyed from Texas Christian to junior college and then to Lafayette in a college career with plenty of travel miles.
Working with a low-90s fastball and a group of secondary options that Arrighetti knew how to spot for effectiveness rather than finding success due to the raw shape or velocity of the pitches, Arrighetti had some funk in his delivery and seemed a perfect fit with an Astros' system that seems to specialize in exactly his profile. Sure enough, Arrighetti has seen the velocity on his fastball tick up to 93-94 consistently with a tremendous ride on the pitch, and his secondaries have each improved notably.
The reliever concern with Arrighetti is still there due to the way the Astros piggyback arms, not always allowing for inning buildup in the minors. This season is erasing those worries for Arrighetti. He opened the season with an 11.05 ERA the first month in Double-A, but since the calendar flipped to May, he's posted a 1.76 ERA and a 0.88 WHIP while striking out 59 in 41 innings, putting him firmly on the map for a potential callup to the big leagues.
VERDICT: The Astros recently shuffled the rotation at the big league level and are seeking a fit to defend their 2022 title. With injuries lingering in the big league rotation, Arrighetti is beginning to look like a very viable option on a pennant-focused club. He should be rostered in deep dynasties, and he's on the cusp of being viable in all dynasty formats.
