Piersall the best Red Sox center fielder? I don't think so. Bradley's the best I have ever seen. Jacoby Ellsbury was pretty good too, and you could make a case for the Fred Lynn of 1975.
I remember Piersall as one of the few signs of life on the soporific Red Sox teams of the 50's. He hit (led the AL with 40 doubles one year), fielded brilliantly, stole bases, argued with the umpires, fought with opposing players and generally acted like he cared.
In one game I saw he hit the ball over the left field wall but it was called foul. He argued vehemently with the umpire. Then he stepped back into the batter's box and in the same at bat - it might have been the next pitch - he hit a home run for real.
After Joe Cronin left to become president of the American League, Tom Yawkey took over briefly and traded Piersall to Cleveland where he had three decent years and led the Indians into a pennant race in 1959. After baseball he had a long career on Chicago radio doing play by play and talk radio.
RIP, Jimmy.
