Mason Auer is a fantasy baseball OF prospect sleeper and minor leaguer to know. Read our MLB prospects outlooks for fantasy baseball rookies and call-ups.
ANALYSIS: The Rays originally drafted Auer out of junior college in the fifth round of the 2021 draft. In his first full season, Auer filled up stat sheets, slashing .290/.372/.487 across both A-ball levels, with 21 doubles, 12 triples, 15 home runs, and 48 stolen bases.
The uber-speedy Auer moved up to Double-A to open this season, but he's really struggled to replicate the power of his bat he showed in 2022. Attempting to find that power has led to a notable increase in strikeouts, as Auer is whiffing at a 41% rate.
He's altered his swing in season, seeking more fly ball contact, but his lack of raw power behind it has led to a 50% fly ball rate, but a ton of infield fly balls as he's struggled to barrell advanced pitching. That said, he has stolen 11 bases in 73 plate appearances this season.
VERDICT: Auer's an elite defender and speed guy, so he has a high floor, but right now, he shouldn't be owned beyond the deepest of dynasty leagues.
