The New York Yankees are gaining ground in the AL East, and part of that surge comes from an unexpected source — rookie right-hander Cam Schlittler. Following New York’s 5-4 win over the Toronto Blue Jays on Tuesday night at Rogers Centre, manager Aaron Boone singled out the one thing about the young pitcher that truly stands out. Schlittler, making just his second big-league start, impressed not only with his fastball and command but also with the confidence he exuded in a high-stakes divisional matchup. Boone emphasized that mentality as a major asset for the team moving forward.
