It started out as a joke, but I think we can definitively say now that Anthony Rizzo is the GLOAT: Greatest Leadoff hitter Of All Time.
With a home run on the second pitch he saw Tuesday night, Rizzo pushed his on-base streak to a perfect 7-for-7 in when leading off games for the Cubs and he extended his overall hitting streak to 14 games. The round-tripper was his third as a leadoff hitter and put him at 16 total bases in that role, just one shy of the aggregate total (with only one home run) put up by all other Cubs leadoff hitters in 63 plate appearances.
