Baseball America unveiled its top 10 prospects within the Red Sox farm system heading into the 2022 season on Wednesday morning. Most notably, there is a new No. 1 in the ranks.

Previously occupied by Triston Casas, infielder Marcelo Mayer has taken over as the top prospect in Boston’s farm system going into 2022.

The Red Sox selected Mayer with the fourth overall pick in this year’s amateur draft out of Eastlake High School (Chula Vista, Calif.).

A University of Southern California commit, Mayer — with some help from area scout J.J. Altobelli — signed with the Sox for $6.64 million in late July and was subsequently assigned to the club’s rookie-level Florida Complex League affiliate in Fort Myers.

With the FCL Red Sox, the left-handed hitting shortstop slashed .275/.377/.440 (121 wRC+) with four doubles, one triple, three home runs, 17 RBIs, 25 runs scored, seven stolen bases, 15 walks, and 27 strikeouts over 26 games spanning 107 plate appearances.

Going into this summer’s draft, Mayer was regarded as perhaps the best prep prospect available, and the Red Sox were able to capitalize on that after finishing with the fourth-worst record in baseball (24-36) in 2020 and thus receiving the No. 4 pick in the 2021 draft.

Mayer, who turns 19 next month, joins an exceptional list of Red Sox prospects to be regarded by Baseball America as the top minor-leaguer in Boston’s farm system, such as Xander Bogaerts, Yoan Moncada, Andrew Benintendi, and Bobby Dalbec.

While Mayer is likely going to start the 2022 minor-league season at Low-A Salem, him moving up to the top spot in Baseball America’s Red Sox prospect rankings means Casas has dropped to No. 2 spot.

Here is how the rest of Baseball America’s top-10 rankings for the Red Sox shake out.
