MLB.com fantasy guru Fred Zinkie fielded questions from fans during a live Twitter chat at @Fantasy411 on Tuesday. Check out the chat transcript below, and follow the @Fantasy411 Twitter handle and MLB.com's fantasy home. Questions and answers have been edited for clarity.
@Beldingsbrother: Who should I pick up: Doug Fister, Jered Weaver, Chris Young or Jesse Chavez?
Zinkie: Pick up Fister, who could thrive within his division later this season.
@ScottMcNally86: What are your thoughts on Byron Buxton for Gregory Polanco and Blake Swihart in an 18-team dynasty league?
Zinkie: I would stick with Buxton. Polanco has struggled vs. lefties, and young catchers are hard to project.
@fjlarav: Who should I drop: Adam Eaton or Kevin Pillar?
Zinkie: Pillar has been a consistent asset this season. It's close, but drop Eaton.
@lele670: Would you trade away Matt Kemp for Yasiel Puig and Logan Forsythe?
Zinkie: For sure. I would trade Kemp for Puig alone.

@swagking1738: Would you trade Robinson Cano and Kyle Schwarber for Jonathan Lucroy?
Zinkie: It's close, but I believe that I would pass on that trade.
@YisroelStern: Choose one outfielder in a 12-team league: Brandon Belt, Randal Grichuk, Josh Hamilton, Cameron Maybin or Schwarber.
Zinkie: I will take Maybin, who can help in five categories.
@coreyd58: Would you trade Anthony Rizzo and Adam Jones for A.J. Pollock and Freddie Freeman?
Zinkie: Even if Freeman was on the active roster, I would not make that trade.
@soxoct27: Would you trade Mike Trout for Kris Bryant and Mookie Betts?
Zinkie: In a keeper league, yes. In a deep one-year league, yes. In a shallow one-year league, no.
@J_Beck132: If I want to get more holds, should I drop Jim Johnson and get another reliever since he got moved to closer?
Zinkie: Johnson is a candidate to be traded soon, and he could be a source of holds again. If you drop him, it should be for a top setup man.

@REgdesBaseball: Should I trade Jacob deGrom and Mark Teixeira for Lance Lynn and Michael Pineda?
Zinkie: No, deGrom is an ace and Teixeira is faring well this season.
@BenjaminDzaldov: In an 11-Team American League-only keeper league, should I trade Hamilton and Daniel Norris for Teixeira and Wei-Yin Chen?
Zinkie: Yes, if you can win this season. Otherwise, you should stick with Norris.
@kyle7may: Should I try to trade Matt Carpenter, or is he going to turn it around?
Zinkie: His trade value is so low right now that you will likely wish to keep him.

@tigerbulldog13: Would you rather own: Yordano Ventura or Marco Estrada?
Zinkie: I would rather own Estrada, as Ventura has been very inconsistent this season.
@rgoldst283: I would like to pick up Rafael Soriano. Should I drop Rick Porcello or Brian Johnson?
Zinkie: Drop Porcello. Johnson has potential, but Porcello may not turn it around to any great degree.
@sptmnky: What should I do with Justin Verlander?
Zinkie: Verlander can be dropped in one-year leagues.
@Beldingsbrother: Should I drop Santiago Casilla or Roberto Osuna for Aaron Nola?
Zinkie: Drop Osuna, who could lose saves to Aaron Sanchez or a veteran if Toronto makes a trade.
@MatthewValdez26: Should I trade Michael Brantley for Max Scherzer?
Zinkie: Definitely. Brantley could get back on track, but he is unlikely to match Scherzer.
Video: LAD@WSH: Scherzer fans eight Dodgers in six innings
@rmbrams91: Would you prefer Adam Lind, Billy Butler or Ryan Howard for the rest of the season?
Zinkie: Go with Lind, who is having a great season despite rarely facing lefties.
@RichieGregor: Should I pick up David Peralta and drop Shin-Soo Choo?
Zinkie: Stick with Choo, even though he hasn't been great. Peralta could lose playing time now that Ender Inciarte is back.
@KyleSkotnicki: Should I trade Clayton Kershaw for Nolan Arenado, Michael Wacha and Stephen Vogt?
Zinkie: Even though Kershaw is arguably the best starter in baseball, make the trade. You are getting three great assets.
Video: STL@CHC: Wacha strikes out Bryant in the 1st inning
@dyl_picks: Which player should I drop: Christian Yelich, Billy Burns, Steven Souza Jr. or Mike Moustakas?
Zinkie: Tough call, but drop Moustakas. He hasn't offered notable power or speed.
@ry200455665: Would you rather own Ian Kinsler or Lance McCullers?
Zinkie: I would stick with the veteran second baseman, as McCullers may deal with an innings limit at some point.
