Sean O’Leary covers Major League Baseball for On SI, focusing on the Giants, Phillies, Orioles, Cubs and Astros. He attended the University of Nevada, Reno to study journalism and film. Writing for outlets such as Pitcher List, SB Nation and FanSided since the beginning of college, he has a passion for covering the sport. Sean also worked for the Reno Aces, Triple-A team for the Arizona Diamondbacks for seven years. Watching so much minor league baseball made him fall in love covering and talking about prospects, much to the annoyance of friends and family.
