Implement a challenge system, MLB

[greymule]

While we're at it, why not an electronic strike zone? Should a team lose the World Series on a 7th-game, 9th-inning called strike on a pitch two inches off the plate? Wouldn't be right.

The PU could still rule on foul balls, checked swings, HBP, balks, etc. (for the time being).

Olympic swimming is timed electronically. Why not sensors in the ball, the bases, the bats, the gloves? Think of the new, fun statistics this would generate: close play out, or CPO, would tabulate the number of times a guy has been out at 1B by less then 0.10 seconds, just as extremely close play out (ECPO) would tabulate the outs by less than 0.03 seconds.

"Tim, if Mike Sample were only a fifth of a second faster to 1B, he'd have 17 more hits this season."

"Thanks, Joe. Very interesting. Let's discuss this for a while."
