Baseball Playoff Strategy

Last two years I've won the regular season and choked in the playoffs in a Head-to-Head league.

As ridiculous as playoffs are in football, it's even more so in baseball. Whatever.

Any strategy used to predict success in these closing weeks of the season? I'm in first by a mile so could afford to lose to pick up players i think will do well, but not sure what else to do other than keep doing exactly what I've been doing.
