Total bases doesn't include walks, just hits. Example, 2006 Juan Pierre had 271 Total Bases from 204 hits. 156 Singles (156), 32 Doubles (64), 13 Triples (39), and 3 Homeruns (12). Gotcha. I always thought they were. That said, isn't this analysis flawed for that very reason? I understand the correlation between TB and runs scored, but hasn't the Cubs' issue been that they've hit well enough to be middle of the pack, but have been so terrible in terms of walks/OBP that they simply haven't scored as many runs as would be expected? If this analysis only takes into account, basically, SLG%, it's probably making the Cubs look better than they really are. That's a valid point, which is why the tool previously referenced by another poster uses both OBP and SLG. But, for what's it worth, consider this: Team ranking in Runs/TB --- Yankees 1/2 Indians 2/4 White Sox 3/1 Phillies 4/5 Braves 5/6 Rangers 6/8 Mets 7/9 Tigers 8/7 Red Sox 9/10 Dodgers 10 So of the top 10 teams in Runs scored, 9 also were top ten in TB, with minimal variation in the rankings. There are naturally exceptions - Toronto was 3rd in baseball in TB, but 12th in Runs. But, Toronto was also 5th in OBP and 2nd in OPS in all of baseball - it's really a complete mystery that they didn't score runs, and they are truly an exception. So you're right, it can happen. But generally speaking, there is a very strong correlation in TB and Runs among the best offenses in baseball.
