I have maintained for years that closing out a tight game is one of the most stressful moments in sports. Everyone can feel the tension. The pitcher, hitter, defenders, managers, umpires, announcers, the fans, even the peanut vendor. Chapman has a very good track record, one of the best, but the first time he walks a couple of guys and blows a save, people will go crazy. We don't need any more stress in our lives , so try to remember that it's just a game.
