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.
@KapDaddyy: Should I trade Giancarlo Stanton for Kris Bryant?
Fred Zinkie: Yes, you should take that deal. Bryant provides as much power and better balance.
@nmach10: Should I drop Jeff Samardzija for Matt Shoemaker?
Zinkie: Yes, you should make that switch. Take out rough starts against elite lineups (Boston, Baltimore) and Shoemaker has been outstanding.
@Owenaldo: Please rank Lance McCullers, Matt Moore, Steven Matz and Brandon McCarthy for the rest of the season.
Zinkie: Matz, McCullers, Moore, McCarthy.
@JJackson1523: Should I trade Drew Pomeranz and Mark Melancon for David Price in a dynasty league?
Zinkie: I wouldn't make that trade. Pomeranz could be similar to Price for the rest of this season and in the coming years.

@MPAllen95: With the Astros signing Yulieski Gurriel, what should I do with Alex Bregman?
Zinkie: I would rather stash Gurriel if you have the option.
@bent0dd: Please pick two out of Nomar Mazara, Michael Brantley and Hunter Pence.
Zinkie: Mazara, Pence. I still have concerns over Brantley's ability to stay healthy this season.
@ZkinsZoe: I've been offered Jake Lamb and Marco Estrada in exchange for Jeff Samardzija and Mark Trumbo. Should I accept?
Zinkie: Yes, you should take that deal. Samardzija hasn't pitched well of late.
@LA_Frankie: With Clayton Kershaw coming back, I need to create roster space. Should I drop Junior Guerra or Zach Davies?
Zinkie: Drop Davies. Guerra is pitching too well to be dropped.

@mattpurwin: Is Michael Conforto worth a roster spot over Justin Upton?
Zinkie: I would much rather have Upton for the rest of this season.
@mbm77: Should I use Trea Turner, Joe Panik or Steve Pearce at my utility spot for the rest of the season?
Zinkie: Go with Panik. He should be back soon. He is very reliable.
@MarkStormbro: Please name a pitching prospect that has received little attention but could debut later this season.
Zinkie: I expect Josh Hader to get some starts with the Brewers. He can be stashed in deep leagues.
@MAS8823: Do you expect Ryan Dull to be a closer by the beginning of August?
Zinkie: I will set Dull's chances of being a closer at 30 percent. That is high enough to make him worth a roster spot in many leagues.

@DanyLavoie: I have Lucas Giolito, Julio Urias and Alex Bregman on my bench. Which one is the best asset for the rest of 2016? Which one is the best asset for 2017?
Zinkie: I will take Bregman as the answer to both questions.
@echo_selzer: Should I use my AL-only waiver claim on Drew Pomeranz? I need hitting more than pitching.
Zinkie: If you need offense, you should wait for additional trades.
@scubafanatic: Are you still high on Evan Gattis? With Yulieski Gurriel impact his playing time?
Zinkie: The Gurriel signing could hurt Gattis. It definitely makes me less enthusiastic for him.
@stepsinpairs: Is Jose Berrios coming back up soon? He's been outstanding in Triple-A.
Zinkie: My guess (and it's only a guess) is that we will see him in the Majors by early August at the latest.
@DavidDoyle2: Please pick two of Matt Shoemaker, Lance McCullers, Sonny Gray and Ian Kennedy.
Zinkie: Shoemaker, McCullers.
@MrMet822: Please rank Carlos Carrasco, Justin Verlander, Trevor Bauer, Carlos Martinez and Aaron Sanchez for the rest of this season and next.
Zinkie: Carrasco, Martinez, Sanchez, Bauer, Verlander.
@ClaggettJim: Is Adam Ottavino going to get save chances this season?
Zinkie: I believe that he will. But likely not this month. I don't think that you need to add him yet in most formats.

@david_carey55: When Tyson Ross returns from the disabled list, would you rather have him over Trevor Bauer or Gio Gonzalez?
Zinkie: I would rather have a healthy Ross than Gonzalez.
@Shadow2actual: Would you rather own Randal Grichuk or Brandon Belt for the rest of the season? Same question for Justin Turner or Travis Jankowski.
Zinkie: Belt, Turner. But I am excited about Grichuk. I don't have much enthusiasm for Jankowski.
@Jpray9: Do you prefer Willson Contreras over Brian McCann?
Zinkie: No, I definitely still prefer McCann.
