The Marlins have opened long-term extension talks with injured ace Jose Fernandez, Christian Yelich and Adeiny Hechavarria, tweets Ken Rosenthal of FOX Sports. As Rosenthal notes, nothing is close with any of the three. Fernandez, a client of Scott Boras, is a particularly long shot to be extended. Boras typically encourages his clients to test the open market, and while his players have on rare occasion signed long-term deals before reaching that point (e.g. Carlos Gonzalez and Carlos Gomez), Fernandez isn’t in a great spot to talk contract as he rehabs from Tommy John surgery.

It’s not hard to see why Miami would have interest in extending Fernandez, however, as he was among the game’s most dominant young arms before undergoing surgery and figures to get back to that point in the near future. The former first-rounder skipped Double-A and Triple-A entirely and debuted in the Majors as a 20-year-old. While that jump would be difficult for most, Fernandez had no trouble acclimating to the Majors and notched a ludicrous 2.25 ERA with 10.3 K/9 and 2.8 BB/9 through his first 224 1/3 innings. He won Rookie of the Year honors in 2013 and finished third in the NL Cy Young balloting that season.

Fernandez is controlled through 2018, although now that he’s missed a season with injury, the Marlins’ decision to have him break camp in 2013 looks even more questionable; Miami could’ve secured another year of team control by leaving him in the minors for just three weeks or so. Of course, if an extension is worked out, that will be a relatively moot point (though still puzzling, in principle).

Yelich, 23 in a month, quietly enjoyed a breakout season. Also a former first-round pick, he batted .284/.362/.402 with nine homers, 21 steals and excellent defense in left field. Baseball-Reference valued him at 3.6 WAR, while Fangraphs pegged him for 4.3 WAR. Yelich can be controlled through 2019 and won’t be arbitration eligible for two more years, so there’s no immediate urgency for the Marlins to extend him. He’s repped by Paragon Sports.

Hechavarria, 26 next April, is a client of Praver-Shapiro Sports and is a more curious case. While most acknowledge that he has the tools to be an excellent shortstop, most defensive metrics peg him as below-average at shortstop despite his affinity for highlight-reel plays. He’s under control through 2018 and isn’t arbitration eligible until next winter. Hechavarria posted an improved .276/.308/.356 batting line in 2014, though his offense still hasn’t caught up to its minor league levels, where he slashed .327/.376/.446 with eight homers in 606 Triple-A plate appearances.

In addition to this group, the Marlins are, of course, trying to extend franchise cornerstone Giancarlo Stanton. Earlier today, reports indicated that talks are ongoing and the Marlins are aware of and comfortable with the fact that Stanton may cost $28-30MM annually.
