I've got to agree with jjgman on this one regarding the pen. I mean, the pen blew a bunch of games early in the year and subsequently, the Cubs were horrendous in one run games. Now, the pen is pitching well, and all of a sudden the Cubs are winning all kinds of one run games. That's only a two run difference but it has mattered. Cubs record in 1-run games: April through June 2: 2-12 June 3 to present: 12-5 That has coincided with the Cubs turnaround. EDIT: I'm not saying that luck has nothing to do with it - I'm sure it does - but the pen has played a bigger role.
