The Royals have called up top prospect Raul Mondesi in order to add him to their World Series roster, the club announced. To clear 40-man roster space, Kansas City designated righty Joba Chamberlain for assignment.
It’s not a traditional top-prospect promotion, as Mondesi — a consensus top-fifty prospect in all of baseball — will make his first MLB appearance in the World Series. While he won’t pick up any service time for that, and figures to return to the minors to start 2016, the 20-year-old does now reach the 40-man roster earlier than was necessary.
Mondesi, whose father was a prominent big leaguer, signed with Kansas City as an international free agent and saw his first action in Rookie ball in 2012 at just 16 years of age. He spent all of this season playing at Double-A, putting up a .243/.279/.372 batting line and swiping 19 bases.
Presumably, the switch-hitting middle infielder will be used mostly for running and defense in his high-leverage debut series. He’ll take the spot of Terrance Gore, the club’s usual post-season burner, while also providing another infield glove.
Meanwhile, Chamberlain will hit the free agent market a bit early, though the move was largely procedural. The 30-year-old joined Kansas City late in the season, allowing five earned runs in 5 2/3 innings. He did not appear in the post-season. Chamberlain will probably be looking for a make-good minor league deal this offseason after a rough overall campaign.
