Seriously, it's Trout's fault if he is out for awhile because he never learned how to slide properly.
If you slide head first it's just a matter of time before you get injured.
All players including Trout should know how to slide feet first by the time they are 10.
You're just begging to get your hands hurt by getting stepped on or jambing a thumb etc or getting your head hurt when you slide head first into someones knee.
I can't believe how many super talented MLB players that can do everything great can't slide properly.
End of rant.
