I thought it would be interesting to compare tournament winning streaks in the careers of Sampras and Federer. Looking at such a streak, one gains an elevated understanding of how consistent they were, as well as, how dominant they were. In Sampras' career, he had two streaks that he won four or more tournaments consecutively. In early 1994, he won 5 in a row (and 7 out of 8) and in the summer of 1999, he won 4 in a row. In Federer's career, he had four streaks that he won four or more tournaments consecutively. In both the summer and fall of 2004, he won 4 in a row, in the summer/fall of 2005, he won 5 in a row, and then in the fall of 2006 and spring of 2007 he won 7 in a row.
