Its uncommon but the Phillies did it last year.
I don't know that this has been the most resilient Cubs team but it's been a thrill to watch over the last couple months. Early in the season they were awful in high-leverage situations both at the plate and on the mound. It felt like they were gonna come up just short and the pen couldn't hold a 1 run lead for horsefeathers and the hitters just couldn't push that tying run over even though they would usually pile up base runners. They are now 19-18 in one-run games but this team really should be on pace for ~100 wins if not for the struggles in HLS. All year they have been among the best teams in just about every significant facet and as we all know they had way more blowout wins than losses (29-17). They've won a lot of series against postseason contenders and at least showed they belonged, although they didn't dominate any of them. But they had one stretch of 2-3 weeks where they really looked out of their depth. Aside from that they have been a really good team.
