This made me wonder when the last time the Cubs have had even a 40 HR season. We've had some mashers in recent years like KB, Javy, Schwarber, Soler, Soriano, ARam. 3 of those 6 have had 40 HR seasons with other teams, just not with the Cubs. KB came oh so close in 2016 with 39 homers, but a September slump kept him under 40. Schwarber also hit 38 in his best Cubs season.
The last 40+ home run season by a Cub was.............Derrek Lee with 46 home runs back in 2005, almost 20 years ago. Obviously Sosa had a bunch of 40+ HR seasons (7 to be exact), but excluding Sammy, the last Cub to hit 40+ HRs in a season prior to DLee was Ryne Sandberg in 1990 (with 40 exactly).
Every team in baseball has had a 40+ HR season more recently than the Cubs except the Giants and the Pirates.
Only 2 Cubs have ever hit 50+ home runs in a season: Sosa (who did it 4 times, most recently in 2001) and Hack WIlson back in 1930.
