From the New York Post:
BOSTON — Might the Yankees have some dirty laundry in their new basement?
A construction worker on a concrete crew at the new Yankee Stadium secretly buried a Red Sox T-shirt under the future visiting clubhouse in an effort to jinx the Yankees.
If these Sauwx fans really want to jinx the Yankees, they would bury Cubs jerseys under the new Yankees home ……. 99+ years and counting!
