Yankees actually have two reasons to trade for a good pitcher by July 31 trade deadline. The first is obvious -- upgrade for a possible playoff run. But Sabathia and Pineda's contracts are up and Tanaka can opt out of his at the end of this season. So acquiring a decent starter not only helps fill a potential 2017 need, but a 2018 season -- and beyond -- need as well.
Just enjoy the ride. Remember, before the Red Sox won their first Series they were pretty notorious for "Crush, Kill, Destroy-ing" their way through April and May only to get a flat tire by June.
Pineda and Severino are displaying consistency they haven't displayed in the last season or two, Jordan Montgomery is pitching well but he's still a rookie. Sabathia is just about done. So hold off on those World Series tickets for now and enjoy the ride.
