MLB.com fantasy expert Fred Zinkie fielded questions from fans during a live Twitter chat (at @fantasy411) on Monday. Read through the best of the Q&A below. Questions and answers have been edited for clarity.
@prjones829: After the Andrew Miller trade, what should I do with Cody Allen?
Zinkie: Sit tight for now. Allen could remain the closer. You'll have your answer in a few days.
@lorenzoNal: Is Aaron Altherr worth picking up in a 12-team league?
Zinkie: Definitely. I would give Altherr some consideration in 10-team formats. He has a nice blend of power and speed.
@cmagee523: Among these injured players, which ones do you feel best about for the final two months of the season: Yoenis Cespedes, Lorenzo Cain, J.D. Martinez, Michael Brantley and Matt Carpenter?
Zinkie: Carpenter and Cain. Among the others, Brantley worries the most.
@mosjeffinitely: Please rank Odubel Herrera, David Dahl and Hernan Perez.
Zinkie: Herrera, Perez, Dahl. I would rank Dahl first if the Rockies trade away a veteran outfielder.

@steve_demita: Would you rather pick up Tony Watson or Kelvin Herrera?
Zinkie: I'd rather pick up Watson. Herrera could have the closer's role for an extended period of time, but Watson almost certainly will have the role for the rest of the season.
@DN1CE23: Do you expect Andrew Benintendi or Yoan Moncada to make a bigger impact this year and next year?
Zinkie: I will take Benintendi for both years. But by 2018, I would much rather have Moncada.
@NJFan76: Please rank these closers for rest-of-season value: Dellin Betances, Roberto Osuna, Alex Colome, Watson and Herrera.
Zinkie: Betances, Osuna, Watson, Colome, Herrera.

@bowty1996: Should I trade away Chris Sale due to the possibility that he gets traded?
Zinkie: You should keep Sale. Being traded is unlikely to give him less fantasy value.
@VAcciardo26: Should I keep Trevor Story or Corey Seager for next season?
Zinkie: You should keep Story. I know that most people would choose Seager. Story will provide more homers and more steals. He also hits in a better lineup.
@GzzPato7: Is Alex Bregman finally going to break out this week?
Zinkie: Bregman is very talented. Give him more time.
@mmledz: What are your thoughts on Jurickson Profar for this year and next year?
Zinkie: I'm optimistic. Profar should be owned in all leagues. He's a good keeper asset.

@khendler6: Should I drop Jeff Samardzija for Jake Odorizzi or Trevor Bauer?
Zinkie: Yes, I'd drop Samardzija for either. I'll go with Bauer.
@carlospudge: What are your thoughts on Jose Berrios this time around?
Zinkie: I haven't given up on Berrios. I would pick him up in any 12-team league and some 10-team leagues.
@chadkiefer: Is Sonny Gray droppable? He's really not pitching well at all.
Zinkie: Yes. If you see a pitcher you want from the waiver wire, you can drop Gray.
@DTBMpls: Does Huston Street survive the week as a closer?
Zinkie: My guess is that Street doesn't survive too much longer, whether it is this week or not. Add Cam Bedrosian.
@jtristanl: Would you rather own Watson or Seung Hwan Oh?
Zinkie: Watson and Oh are very similar in overall value. I'll take Oh.
Video: STL@NYM: Oh finishes off a 5-4 win for the Cardinals
@TerminiMike: Please pick one: Max Kepler, Tyler Naquin or Dahl.
Zinkie: I'll take Kepler for the rest of the season. I would take Dahl if he had a more secure role.
@LouieRanks: Should I drop Allen and pick up Miller?
Zinkie: You need to pick up Miller, but don't drop Allen yet. Wait a few days and then decide.
@NJFan76: Is it time to grab Yulieski Gurriel if I have an open bench spot? Or is playing time an issue once he reaches The Show?
Zinkie: Playing time could be an issue. That being said, I would grab Gurriel if I had the necessary bench space.
@Matt2628: Please rank Matt Kemp, Adam Duvall, Stephen Piscotty and Cain.
Zinkie: Cain, Piscotty, Duvall, Kemp.
@perez_raudy: Please rank Anthony Rendon, Trea Turner, Neil Walker and Addison Russell.
Zinkie: Rendon, Turner, Russell, Walker.
Video: WSH@SF: Rendon hammers a two-run homer in the 2nd
@Mitch11Lang: Should I accept an offer of Bryce Harper for Sale?
Zinkie: Take the deal right away.
