Watch: Ortiz ties Ted Williams on all-time HR list

From one Boston Red Sox legend to another.

David Ortiz mashed his 521st career home run Friday to straightaway center field at Fenway Park, tying Ted Williams' career mark. He's also now tied with Williams, Willie McCovey, and Frank Thomas for 19th on the all-time home-run list.

With his 18th homer of the season, Ortiz is just two shy of Mark Trumbo and Nolan Arenado for the league lead in what's quickly becoming a historic retirement campaign for the 40-year-old.
