The Rangers traded Montero to the Mariners on December 15, 2020, and a player to be named later in a deal must be selected within six months, under MLB rules, so the Rangers apparently waited until the last possible moment to make their pick. The Rangers also received pitcher Jose Corniell from the Mariners at the time the deal was announced.
Both Mesa and Corniell were part of the Mariners’ 2019-20 J-2 class. Corniell received a $630,000 signing bonus at the time, with BA describing him as a big, hardthrowing righthanded sinker ball pitcher. Mesa is a shortstop who received a $500,000 signing bonus, getting praise for his athleticism, speed and arm.
The Rangers have indicated that Mesa will start the year with one of the club’s DSL squads. BA had a story earlier today saying that AZL action will begin on June 28 — two weeks from today — while DSL play will begin on July 12.
