Shortly after the Yankees’ season ended with a Game 7 loss to the Astros in the ALCS, Masahiro Tanaka wasn’t ready to wrestle with his contract status. Tanaka can opt out of his contract three days after the World Series ends, and if he does, he will be leaving three years and $67 million behind. After a pedestrian 13-12 record and a 4.74 ERA during the regular season, it didn’t appear Tanaka would opt out. Then Tanaka went 2-1 with a 0.90 ERA in three postseason starts and surely impressed other teams. “Not at this point in time. Just disappointed in how things unfolded for us,” Tanaka said after Saturday night’s 4-0 loss. “I haven’t had a chance to think about my contract.” Tanaka didn’t know what sort of impact his solid postseason would have on other clubs.
