According to Fangraphs and Baseball-Reference’s WAR (Wins Above Replacement) calculation, Jeff Francoeur is the the worst player in the game, though he’s not the worst ever.
Jerry Royster‘s 1977 with Atlanta, a -3.7 FanGraphs and -4.1 B-R debacle. The utilityman hit .216/.278/.288 and, the metrics say, played brutal defense.
Baseball Reference ranks Frenchy’s WAR at -3.0 — the 11th worst season for an offensive player since 1901.
With a dreadful August and September, Francoeur could threaten the season both sites agree is the worst ever.
