He holds a number of records for bad hitting, such as an 0 for 44 streak with the Brooklyn Superbas in 1909. This was the longest hitless streak by a non-pitcher for over 100 years; Bob Buhl holds the overall record with an 0 for 87 skein, including 0 for 70 in one season. However, when Craig Counsell went 0 for 44 with the Milwaukee Brewers in early August, 2011, it brought new attention to Bergen's streak, which was then thought to have been of 45 at-bats. SABR researcher Joe Dittmar reviewed the play-by-play data for that season and confirmed on August 12th that Bergen's streak was in fact of 44 fruitless at-bats, meaning that Counsell had tied him. Bergen also has the lowest career batting average (.170) of any position player (i.e. non-pitcher) with 1000 or more at bats, and the lowest average of anyone with more than 2000 plate appearances - pitchers included.
He was the brother of catcher Marty Bergen.
Bill's minor league career stretched from 1898 to 1917, and afterwards he managed semi-pro teams.
