Quotes: In February as he entered Spring Training with the NL Champion Mets Bastardo had this to say: "If our pitchers dominate from the first to the sixth or seventh inning, [opponents] aren’t going to have a chance. They’ll be frustrated from beginning to end. The team was in the World Series and competed the whole year. That makes me think we can be in that spot this year, for sure."
