David Vincent (1949-2017) was the preeminent expert on the history of home runs — which earned him the nickname "The Sultan of Swat Stats." Vincent was the 1999 recipient of the Bob Davids Award, SABR's highest honor; the first and only secretary for Retrosheet; and the Washington Nationals' lead official scorer since their inception in 2005 until his untimely death in 2017. A SABR member since 1985 who served for four years on the Board of Directors, he spearheaded the effort to organize and digitize the comprehensive SABR Tattersall-McConnell Home Run Log, a record of all home runs hit in the major leagues since 1871, which is now available online through Baseball-Reference.com largely because of Vincent's work. He authored or co-authored several books, including Home Runs in the Old Ballparks (1995), SABR Presents The Home Run Encyclopedia (1996), The Midsummer Classic: The Complete History of Baseball's All-Star Game (2001), Home Run: The Definitive History of Baseball's Ultimate Weapon (2007), The Ultimate Red Sox Home Run Guide (2009), and SABR's Great Hitting Pitchers (2012), along with numerous other articles on home runs and hitting. Vincent also contributed many articles to SABR's Baseball Biography Project, the Baseball Research Journal, and SABR Digital Library publications. Click here to learn more about his life.
