As we are always reminded: size matters, and you know what they say about a guy with a really big face? He's a home run hitter. Two London researchers have released a study in which they link a ballplayer's ability to hit home runs with the size of his face. Holy jowl implants!

Hikaru Tsujimura and Michael J. Banissy of Goldsmiths, University of London came to their conclusion after studying home runs hit by Japanese baseball players over a two-year stretch. The researchers found that those players whose faces had a greater width-to-height ratio had higher home run totals. Previous studies have shown this correlation with other athletic performance, but only in athletes of Caucasian descent.

It seems more like correlation than causation, though the study's premise notes that "a high width-to-height ratio has been linked to the strength of hand grip, the drive to achieve, and competitiveness." Home run hitters like Miguel Cabrera and Prince Fielder have big noggins, but they are big guys who rock the post-game buffet as well as opposing pitchers. What about guys like Ryan Braun or Giancarlo Stanton? They can go big fly without having big melons. That makes us skeptical.

As interesting as the study linking home runs to face size is, it's unlikely to have any impact on major league scouting. However, if you start seeing a bunch of big leaguers who look like human PEZ dispensers, you'll know that there may be some real truth to the study's findings.
