I've never thrown a 165km/h fastball in any inning of any game, let alone the ninth, but I'm guessing it requires effort. And Justin Verlander's pit stains in this vid would seem to confirm that.
OK, I know that's most likely shadowing, but seriously, when Verlander starts his windup at 0:28, he's not exactly a Right Guard ad. And while uniform dirt and degradation have been a part of sims for years now, isn't it time we start integrating some sweat and stank?
MLB 2K10 is out March 2. But it is not Smell-o-Vision enabled.
