An on-screen graphic during last night's Red Sox game stated that Mookie Betts is the only player in Red Sox history to have hit 15+ home runs and 15+ stolen bases in three consecutive seasons.
* Please keep in mind that Mookie Betts has played only three full seasons in the major leagues.
I went to Baseball Reference's always-amazing Play Index to investigate.
Three other Red Sox players have had three or more 15/15 seasons, but they were not consecutive: Jackie Jensen (1954, 1955, 1959), Reggie Smith (1967, 1968, 1972), and Dustin Pedroia (2008, 2009, 2011, 2012).
