Hearns wins, that killer Jab and destructive right hand will do the job. You can't outbox Hearns as he showed against Virgil Hill, Benitez and Sugar Ray Leonard. Only slug him and constant relentless pressure in his face and not giving him a breathing space. Hearns is the best 154 boxer based on resume alone. Duran who destroyed Davey Moore + Benitez who stopped Duran/Maurice Hope.
Hearns by decision. UD but rather close. Probably similar to how he beat Benitez. Not a onesided fight at all. Winky was a solid fighter.
Hearns decision. His longer reach and phenomenal jab would be a deciding factor. Winky's high guard wouldn't be as effective against Hearns's jabs and straight rights down the middle. Hearns's height and reach would make it difficult for Wright to counter effectively and he'd be finding himself being countered over top of his own counters because Hearns was quicker and would be ready for Wright to come out of his shell. Wright had a good enough chin and guard to last the distance, but not enough else to win. The fight sequence would be something like this: Hearns jabbing and then throwing his right hand when Wright stepped into the proper distance. Wright would keep his guard high and tight (as usual) and look to get his own jab working and counter off of Hearns's punches. Hearns would quickly learn to bait Wright out of his guard and then counter the punches that came his way and then repeat the cycle. If Hearns felt Wright was being too defensive, he'd begin to press more and maybe get tagged from time to time, but not enough to cause any real trouble.
This is a lot more of difficult fight than people think for Hearns. Winky with that excellent southpaw jab and high guard defense can really neutralize a lot of Hearns strengths. I still would favor Hearns but Wright really figured out how to fight to his strengths later on in his career and down right made great fighters like Mosely and Trinidad look bad at times. Hearns by UD but not without concern. Styles make fights.
The younger Wright who was more of a boxer-puncher with slightly more aggressive inclinations gets obliterated. Vasquez yoyoed him and though Winky did well for six rounds or so there, he'd have been lucky to last four rounds against Hearns fighting like that. Obviously Winky changed quite a lot between then and his 2003-05 peak, and his wins against Mosley (first fight in any case) and Trinidad were as comprehensive as it gets in terms of stylistically dominating an opponent. But there's a world of difference between shutting out a one-dimensional, post-prime Trinidad, or shoving a smaller Mosley around the ring, and facing a prime Hearns at 154. Wright doesn't hit hard enough to pull off a Leonard or Barkley here, and isn't facing someone who is a sucker for a jab, ala Mosley or Tito. Hearns' own jab is at least comparable to Wright's and he's got the speed advantage, greater variety of shots and of course awesome power. If Leonard and Benitez can't find a way to outbox or figure out Hearns for twelve and fifteen rounds respectively, then I don't see how Winky's tight, effective but ultimately repetitive and no-frills style does. Just don't see a way for Winky to win this one.
