Yankees might have to count on Masahiro Tanaka in wild-card game. Nowadays, Tanaka is not the Yankees’ go-to guy. If they host the American League wild-card game on Oct. 3 — the most likely outcome at the moment — Luis Severino almost undoubtedly will get the nod. Unless . . . Manager Joe Girardi threw a curveball into the Yankees’ postseason pitching picture when he started Severino, and not Tanaka, against the Twins on Wednesday. Girardi wasn’t positioning the Yankees for the wild-card game. He was positioning Severino for a possible start on the final day of the regular season if the Yankees still have a chance at the AL East crown. http://www.newsday.com/sports/baseball/yankees/masahiro-tanaka-eager-to-show-his-best-form-in-postseason-1.14243948
