The end of the regular season is upon us, and I have to admit that it snuck up on me a bit. Let's take a look, by position, of the breakout stars and fantasy duds. We knew we would see high-profile players end up with poor numbers, just as we knew that formerly lesser players would put up numbers in 60 games that they wouldn't likely manage in a full season.
Stud – Travis d'Arnaud, ATL
d'Arnaud was fine last year, batting .251/.312/.433 with 16 homers in 391 plate appearances, but he's been elite this year, batting .338/.400/.568. It seems unlikely he'll do anywhere near that over a full season, but he's certainly not fading this month, posting a 1.071 OPS in September. I'm pretty sure a .418 BABIP is not sustainable, but, then again, d'Arnaud has posted an excellent 50.5 percent hard-hit rate. He should be able to at least hang on for a few more years now and would be one of many players who could benefit from an NL DH should he stick with the Braves or another NL club.

Sanchez is hitting .267/.333/.667 in his last eight games, but there's really no time to save a season for a guy batting .151/.253/.396. He does have 10 home runs, so the power hasn't fallen completely apart, but a 36.7 K percentage is going to make any hitter's line look poor. He's somehow posted a .155 BABIP despite a halfway
