On December 11, 1995, Mariano Duncan signed with the New York Yankees, and he spent a season and a half in New York. In his only full season in 1996, he hit .340 with 56 runs batted in. Duncan coined the phrase, "we play today, we win today... das it!" which became the mantra for the 1996 World Series champion New York Yankees. Many of the players wore t-shirts with the slogan under their uniforms daily. Mariano Duncan has hand signed this New York Yankees 8x10 Photo with 96 WSC inscription. Certificate of Authenticity from Athlon Sports. Custom White Mat and Premium Black Frame as shown.
