In this episode of My First Ballgame, we are joined by my good buddy Mark Feinsand of MLB.com, who co-authored one of the greatest baseball books ever written: "Mission 27," with the 2009 New York Yankees. We revisit Mark's first trip to Yankee Stadium on May 5, 1979, a 5-4 walk-off Yankees win over the Athletics. We'll touch upon what it was like to be in a Yankees clubhouse with Reggie Jackson, marvel at Tommy John "working on an 11-hitter," talk about riding the New York City subway in the 1980s, being in the stands for the Jeffrey Maier game, covering the Aaron Boone game, and learn about Mark's fateful interview in George Steinbrenner's office.
