The likeliness that Jimenez is to blame can also be traced back through his history with the Rockies. Jimenez is open about his joy for playing for Cleveland, in comparison to the Rockies. There seems to be resentment towards Colorado. Troy Tulowitzki stated that Jimenez disliked his time with Colorado and had an open desire to leave. This would suffice as reason for why Jimenez struck the Rockies' star player.
But were the Rockies unappreciative of Jimenez's talents? This idea places at least some of the blame on Colorado. Why did Jimenez not feel like the Rockies were a team he could succeed with? Can we even prove that the pitch did not get away from Jimenez?
So maybe Tulo has a swollen elbow because Jimenez was being a jerk, or maybe the Rockies really outcast Jimenez from the start. There is, however, a potential third location to place blame- the ball. This sport, and the rivalries that go along with it, would not exist if it was not for the ball that controls everything. This idea of the ball as a deodand- the object responsible for the crime, makes sense. It was after all, technically the ball that hurt Tulo's elbow, not Jimenez. Jimenez could not have thrown the painful pitch if there was no ball. Though this may seem like a silly culprit, it also seems highly logical. Like in Underworld, where Nick's ball is deemed a "murder weapon", could not this act be the objects fault?
Personally, I place my blame on Jimenez. I am a Rockies fan, and especially a Tulo fan, so my bias does come into play. But in situations such as this, it is necessary to consider all the possibilities of who, or what is responsible. This prevents us from jumping to conclusions as the media so often does.
