David Ortiz of the Boston Red Sox took 33.39 seconds to round the bases on April 9th after hitting a home run against the Rangers. Sports Illustrated clocked his time at 32.91, but upon further review, the time was actually 33.39. According to tatertrottracker.com, that is the slowest home-run trot since they starting recording them in 2010.
It is really no surprise the (maybe) 230-pound designated hitter took so long. Maybe instead of calling him Big Papi, they should call him Big U-Haul.
