10. Del Pratt (1918-1920)
Pratt spent the majority of his career with the then St. Louis Browns but made an impact in three seasons with the Yankees in the prime of his career. He slashed .295/.348/.394 over the three years with a combined 219 runs batted in.
His most notable season with the Yanks was in 1920 when he featured a .314/.372/.427 slash and 108 RBIs while playing in all 154 games on a team that game three games short of the American League Pennant.
Had Pratt stayed in New York, he very well could have been a cornerstone for a franchise that took home its first championship in 1923.
