With a resurgent farm system, more and more Mariners fans are becoming invested in the minors, but even the most attentive fans could be excused for not knowing the name of DSL centerfielder Jonatan Clase. When baseball’s international signing day rolls around every July 2, some international prospects garner more attention than others: pedigreed prospects who work with some of the most respected trainers, net the largest signing bonuses, have famous lineage, or just stand out in some other way, like 6’7” Pirates shortstop prospect Oneil Cruz. For every six or seven-figure signing bonus, though, are a baker’s dozen of players who sign for much more modest amounts, who don’t have a perennial All-Star father, or haven’t dazzled scouts with a loud power tool or sterling defense at a showcase.
