Derek Shelton has pulled the move a couple times this season. He will go out to the pitcher's mound with two outs not to immediately pull his starter, but to have a conversation with them about how they were feeling and how they want to attack the batter. If he likes what he hears, he heads back to the dugout without ever pointing to the bullpen.
He did it in the eighth inning Wednesday at PNC Park, having a chat with Bryse Wilson, who was amidst the best pitched game of his major-league career.
