David Peralta - The standard September caveat of "make sure he's in the lineup" applies, but I like Peralta very much against Christian Bergman tomorrow. Peralta is priced at $3600 and is hitting 318/375/541 against RHP this year. I also still like Peralta for 2016....as a late conversion from pitching, he may very well still be developing as a bat despite his age (28). He's hit 352/388/560 in the second half with 9 HR and 5 SB. He has been protected a ton against LHP, and while he does struggle a bit against them (253/318/380 in 79 ABs), he's less helpless than many. A bit more PT against LHP could help him push the RBI total up near 100. He's a very underrated player.
J.A. Happ - Happ continues to pitch extremely well for the Pirates, tossing 6 innings of 1-hit ball against St. Louis on Monday. He struck out 4 without walking a man, needing just 56 pitches to get through 6. His velocity was up as high as I've ever seen it, touching 93 at times, and his command up in the zone is much improved. I hate to sound like a broken record, but the move to the NL is a big deal for a lot of arms, and Happ certainly falls into that category. I would watch his free agency with interest this offseason, as there are about 12 destinations for which he would be a clear #4 or #5 SP for me in 2016 (all NL outside of ARI, COL, and maybe CIN).
Trea Turner - Turner started and went 1-3 with a walk and a CS on Monday. The 22 year old has 25 2Bs, 7 3Bs, 8 HRs, and 31 SBs across three levels this season, and with a very mature, patient approach at the plate to go along with a solid defensive reputation, he may very well be the starting SS for the Nationals in 2016. He doesn't have a lot of power (hard contact rate of barely over 7%), but with an excellent contact rate and good speed he profiles as a #1 or #2 hitter potentially...I expect him to be a worthwhile draftee as a MI next spring if he has the inside track on the SS job.
Lance Lynn - I like Lynn, who tossed another 5 shutout innings on Monday in Pittsburgh, and he's been a pretty underrated guy for a few years now. I don't like the drop in velocity and continued degradation of control that I've seen this year. That xFIP ERA keeps creeping upward, and sooner or later that's going to manifest itself in things that count for fantasy purposes. I'll likely be avoiding him next year unless his value drops quite a bit from where I expect it to be.
Enrique Hernandez - There are so few legitimate "sleepers" in any sport anymore....information flow is simply too fast, constant, and omnipresent. Hernandez is perhaps an exception, as for various reasons he doesn't get a ton of press. Hernandez is barely 24, and has increased his power numbers consistently and substantially over the past three years, and his avg HR distance this year of 411 feet speaks to even more potential down the road. The line drive rate of 24.5% should keep the AVG in a reasonable state as well. He was activated from the DL Monday, but the point here isn't for 2015, but rather for next season. The Dodgers payroll is a complete mess. They have over $45 million dedicated to 3 OFs, none of whom are named Joc Pederson or Enrique Hernandez, in addition to $80 million on 4/5 of a rotation. We haven't even gotten to the infield or bullpen yet, where there are plenty of redundancies as well. The easiest path to PT that I could potentially see for Hernandez is at 2B, where Alex Guerrero would be his likely competition. He also could continue to be used as a super-utility guy, picking up 400 ABs that way. The point is, it's going to be difficult for him to pick up enough playing time to be a viable option in all formats, although the possibility exists. I would definitely be looking at him in deeper leagues and NL-only formats in the spring, and if it looks like enough PT is there I'd grab him just about everywhere else.
