I think I'd put Ray Oyler dead last. Or Tom Matchick.
Not in a league with those guys, but Bobby Wine was pretty bad for a long time. As was the immortal Enzo Hernandez. And Dal Maxvill was sort of the NL version of Belanger.
The 1968 Tigers won the pennant with the troika of Oyler (.135/.213/.186), Matchick (.203/.248/.286), and Dick Tracewski (.156/.239/.236) manning shortstop for them. Obviously a case of a manager valuing his players' defense so much he overlooked the offensive shortcomings.
Well, maybe not entirely overlooked. Remember, those three were so punchless Mayo Smith turned his Gold Glove-caliber centerfielder into a SS for the World Series. (What Smith really did was replace Oychickski's bats in the order with Al Kaline's. The Tigers basically had four starting outfielders that year - Kaline, Mickey Stanley, Jim Northrup, and Willie Horton - and in those pre-DH days, moving Stanley in to SS was the only way Smith could get all four guys in the lineup at the same time. You could say it worked, I guess. Also, legend has it that Smith - a good card player and convival drinking buddy of sportswriters never noted in his time for being particularly tricky as a manager - pulled the Stanley at SS idea out of his ass just prior to the beginning of the Series. But a quick check of the game logs at retrosheet shows Smith started experimenting with Stanley at SS as early as late August, and he started him at short exclusively the last week of the regular season. Starting Stanley at short in the World Series was still a gutsy move, but not an entirely un-premeditated one.)
