Lenny Dykstra, we are told in the book Moneyball, was built emotionally to play baseball, as opposed to friend and star of the book Billy Beane, who was built physically but not emotionally to play baseball.
The book recounts a story of the two watching a pitcher warm up.
Who is that, Dykstra asks.
Steve Carlton, one of the best, Beane says.
I'll get a hit off him, Dykstra says.
Beane was already thinking about Carlton's nasty pitches, working about the future.
This is paraphrased to clean it up.
I never liked Dykstra, but apparently his mindset is what I need.
