Jake Arrieta was a journeyman two years ago, last year he won the Cy Young. Fortunes in baseball can turn on a dime, I've seen it happen many times. Bradley won't keep this torrid pace up, but the way he's swinging the bat suggests he's adjusted his mechanics at the plate and clearly has more confidence. If he finishes the season hitting .280 with 20 HR's, he'll have done great. He's here for his defense, anyway, so good offensive production from him is just a bonus.
