I was down on him after glancing at the box score, but after actually watching a recap of the 9th, I'm much less upset. He had two batters K'd, and would have had great ninth inning and the save if that one throw to first had been a half second quicker, or if the baserunner had been a half second slower. Then he just got beat on one pitch. Not a huge deal. It happens.
Using a key to gouge expletives on another's vehicle is a sign of trust and friendship.
