I usually don't question his decisions, but why have arguably your weakest bullpen pitcher, a lefty at that, pitching to a right hander in a 3-3 tie game in the bottom of the 9th on the road? When your closer and other stronger pitchers are completely rested due to the starters pitching long innings the past few games?
Of course he gives up a first pitch walk off home run to a batter hitting .147
