10:50am: Victor Victor’s bonus checks in at $5.25MM, while Victor Jr. received a $1MM bonus, per Sanchez (Twitter link).

Oct. 22, 9:55am: The Marlins have formally announced the signing of the Mesa brothers and will be streaming a press conference to introduce the pair at Marlins.com and also on Periscope.

Oct. 20, 2:48pm: Victor Victor is expected to receive a bonus in excess of $5MM, per MLB.com’s Jesse Sanchez on Twitter.

2:12pm: Jon Heyman of Fancred tweets that the Marlins have officially signed the brothers. Terms of the deals have yet to be released.

1:15pm: Cuban outfield prospect Victor Victor Mesa and brother Victor Mesa Jr. are expected to sign with the Marlins at some point in the next few days, according to Jorge Ebro of El Nuevo Herald. The news is certainly not official yet, but an unnamed source claims the brothers have passed physicals and will be introduced “imminently” at a Marlins Park press conference (at which Executive Director Derek Jeter and President of Baseball Operations Michael Hill are slated to attend) scheduled for 11 AM Monday.

Victor Victor, 22, was arguably the most coveted amateur free agent on the International market at current, and Ebro’s sources indicate that he’s expected to receive a bonus in excess of $4MM. Mesa Jr., 17, is expected to receive a bonus “close to” $1MM, per the report. Right-hander Sandy Gaston, oft mentioned in concert with his countrymen, appears to be headed elsewhere, per Ebro, though FanGraphs’ Kiley McDaniel tweets that “the belief” is that Miami could still find a way to fit him in their ~6.75MM bonus pool, too.

Victor Victor, the son of Cuban baseball luminary Victor Mesa, slashed .354/.399/.539 for Matanzas in his last full season of play (2016-2017, when he was just 20) in Cuba’s Serie Nacional. Reports have indicated that he may need just minimal seasoning in the minors before getting his shot with the big club, with MLB.com taking particular note of his “outstanding” defense, plus throwing arm and running ability, and potential to hit at the top of a lineup. The older Mesa starred in a recent showcase at his soon-to-be new home park, where he impressed scouts during a live batting practice session. Mesa Jr.’s calling cards appear to be an above-average arm and plus contact ability, though at age 17, he certainly has plenty of projection remaining.

The addition of the Mesa brothers, particularly the elder of the two, is an important step in the Marlins’ ongoing rebuild of the organization under new ownership. Last offseason’s trades of Giancarlo Stanton, Marcell Ozuna, Christian Yelich and Dee Gordon marked a clear retooling effort with a focus not only on shedding payroll but also adding a wave of young talent to the organization. This latest pair of additions will only further the goal of creating a foundation of intriguing young players. With most of its pool now exhausted, Miami will look to offseason trades and a favorable No. 4 overall selection in the 2019 draft as additional avenues to bolster its growing reservoir of prospects.
