Put a milo on him
From Wiki Gonzalez
"Put a milo on him" is believed to have nothing to do with ripping off the arms, like the Venus de Milo.
Actually, this phrase is another contribution from Moneyball. In an episode from the book, Billy Beane was informed that an amateur prospect he was considering drafting for the Athletics had a sketchy record of behavior in his past. Beane immediately ordered his underlings to "put a milo on him": i.e., don't select him.
It is believed that Michael Lewis included this tidbit to emphasize that Beane, contrary to his reputation among baseball men as a number-cruncher guided only by statistics, puts some valuation on character and makeup in scouting potential ballplayers. This was later emphasized when Lewis described the reasoning behind the John Mabry-Jeremy Giambi trade and Beane's acquisition of veteran catcher Scott Hatteberg.
The phrase has nothing to do with this either.
