No, it does not show that at all.
Look at teams over the years. A team will have a great record in one-run games one year, and with virtually the same roster the next, they will have a losing record. It does not show a team "can't" win close games.
If the Cubs are winning and pile on runs, they win by more than one. If they are down three and get two, they lose by a run. In your scenario, both of those things are bad. Makes no sense.
There is no such thing as "knowing how to win one run games".
Its a different year, different situations, different everything
You can't compare years...
I guess I should of mentioned low scoring games not 10-9 type for offense...
If their 1-2 runs losses are mostly low scoring games, then usually it comes down to lack of execution that costly.
Like getting runner home from 3rd less then 2 outs..
Not being able to hunt a runner over..
Leaving a bunch of RISP
Etc Etc
On the pitching side, if a team losing a bunch of 1-2 run games
Usually the blame would go to the Pen because they can't hold a lead late..
