Dave Lopes had a nice stolen base streak for about 2 1/2 months in 1975. If this picture was taken during the streak, it would have been on August 8, 9 or 10, 1975.
Vince Coleman has the record now -- he stole 50 bases in a row from 9/18/1988 to 7/26/1989. Ichiro almost broke the record in 2007, but he fell short when he was caught stealing on May 17. He had 45 in a row at that point.
