Astros Doug Fister retires Mike Trout with a ground ball off the bat knob

Mike Trout is arguably the best player in Major League Baseball. Thus, teams have resorted to som interesting tactics to keep his impact on the game to a minimum. But Doug Fister took unintentionally to another level -- hitting his bat knob.

The Angels had a runner at third with two outs in the third inning. Mike Trout was at the plate with a 3-2 with Fister on the mound in the third inning. Fister has already gone up on the first pitch, dusting Trout back from the plate.

On the sixth pitch of the at-bat, Fister again went inside on Trout. The ball appeared to have hit Trout, this time. The umpire called for a dead ball and motioned for Trout to got to first.

Fister fielded the ball that landed in fair territory and completed the play with the first baseman Marwin Gonzalez.

Things got interesting when Astros manager A.J. Hinch asked for a review of the play. Upon reviewing the play, the ball appears to clearly hit only the bat knob instead of Trout's hand.

I have to assume the game plan is to aim for the bat knob going forward, right? It worked this time. What could go wrong next time?
