So Chase Utley slid into second hard enough to break up the double play, and break Reuben Tejada's leg.
Similarly, Chris Coghlan had a similar slide which broke Jung-Ho Kang's leg, earlier in the season.
In both cases, the runner ran far behind second base, with no attempt to even touch the bag.
In both cases, the runner started their slide so late, they could not have even stayed on the bag.
The rules already exist to prevent this stuff. Is it time to get umpires to start enforcing the rules?
For instance, if a runner runs into a defender, without even touching the bag, I think both he, and the runner going to first should be out. Additionally, that player should be tossed out of the game, and possibly suspended.
Utley better watch himself for the rest of the series.
