I work out everyday and I guarantee you I would score before he made it to third base. My marathon pace is nearly as fast as his sprint pace. Heh, that might be a stretch. The other night, Prince scored from first on a triple by Hart before Corey stepped on 3B. Granted, Prince had a head start of his lead at 1B, but I hear Hart is rather speedy. Prince is certainly a big guy, but he also a pro athlete. He's much, much faster than many catchers, and considering his youth, while heavy, is still probably in pretty good shape...he never has to stop at 1B on a ball down the line or in the gap, for example. A double always ends up as a double. I believe they timed Prince on one of his inside-the-park HR's and it was 16 seconds, or something like that. While that's possible to beat, for most of us, it is ridiculous to think about, even back when I was in the best shape ever. Of course, until you can drive balls 450 feet off the top pitchers in the world, it's all moot. I think it is safe to say Fielder is a good bet to age badly. But, he's likely to be very good until he hits 30.
