Bumgarner also approached Hubbell last season, posting a 1.114 WHIP while finishing 16-11 with a 3.37 ERA. The only other San Francisco-era Giants pitcher to challenge Hubbell in WHIP was Atlee Hammaker, who had a league-best 1.039 figure in 1983.
You can win a trivia contest by naming who currently owns the third-best WHIP by a San Francisco left-hander: John Cumberland, who checked in at 1.124 in 1971.
Somewhat surprisingly, Mike McCormick's 1967 Cy Young Award season for the Giants (22-10, 2.85 ERA) produced a solid, but not remarkable 1.147 WHIP. Johnny Antonelli actually had a better WHIP (1.145) during a 19-10 season in 1959.
