On this episode, we focus on the toughest defensive job in baseball, playing center field at Coors Field. Rockies rookie Brenton Doyle is doing it and doing it well. Mark Simon talked to Brenton about how he does what he does defensively and how his defensive game has developed dating back to his Division II college days (0:39). SIS VP of Baseball Bobby Scales just watched Doyle play live and shares his thoughts on his game, as well as the outstanding defense of Rockies shortstop Ezequiel Tovar and third baseman Ryan McMahon. He also pays tribute to one All-Star close to his baseball heart (10:27).  Then we're joined by Saberseminar co-founder Dan Brooks, who talked about the return of the baseball statistical conference this August in Chicago. It's a fantastic chance to hear interesting speakers and network, with all the money raised going to a great cause (18:19). Thanks as always for listening.
