Meet Scott Boras, the superagent who scored the Nats their top talent—at top dollar.

Boras seems to get his way at least in part through willpower. Jerry Maguire he is not. During negotiations, Boras doesn’t scream. He isn’t manic. Baseball insiders consistently describe him with two words: prepared and relentless.

“At meetings, a GM might have the executive suite in the hotel—Boras has the presidential suite,” says Bowden, the Nats’ former GM. “He’s up jogging at 5 am. You walk into the arbitration hearing and his eight guys have Armani suits and matching ties. I worked in baseball front offices for 25 years. I never met anyone looking forward to a negotiation session with Scott Boras.”
