Guests: Blue Jays reliever Mason Fluharty, pitching coach Pete Walker, Toronto Star baseball columnist Gregor Chisholm   This week in Deep Left Field, we introduce you to rookie left-hander Mason Fluharty, who came within six outs of throwing a "perfect game" out of the bullpen. As the Jays hit the one-quarter mark of the season, we catch up with pitching coach Pete Walker for his thoughts on how the pitching has held up so far, with a focus on the starting rotation, and Gregor Chisholm and I share our thoughts about the controversial MLB decision to remove all deceased players - including and especially Pete Rose - from baseball's Permanently Ineligible list.
