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.
@KevinWiles: Should I drop Tyler White for Byung Ho Park?
Fred Zinkie: I'm fine with that switch. Park's power production is likely more sustainable than White's power.
@dkuhlman0420: Yu Darvish just got dropped in my league, should I go ahead and pick him up?
Zinkie: Definitely. Darvish could be a borderline ace by the beginning of June.
@JasonStier: Bryce Harper and Matt Holliday for Andrew McCutchen, Matt Harvey and Jose Berrios. Which side do you prefer in a keeper league?
Zinkie: The Harper side. It's highly unlikely that I would trade away Harper in a keeper league.
@tgraham907: Is Michael Conforto for real? Where does he fit among my outfield of Lorenzo Cain, Dexter Fowler, Yasmany Tomas, and Stephen Piscotty?
Zinkie: In your outfield, he ranks in a tie with Fowler as the second-most valuable asset behind Cain. Yes, Conforto is for real.
@bfont_17: Should I pick up Chris Carter or Brandon Drury for Kolten Wong?
Zinkie: Yes, pick up Carter.
@thealexmoretto: Please rank these players for the rest of the season -- Victor Martinez, Conforto, Wil Myers. Should I drop Randal Grichuk or Corey Dickerson for any of them?
Zinkie: Conforto, Martinez, Myers. I would drop Grichuk for Conforto.
@sancarlosbrad: Who is the best hitting prospect that will come out of the Minors in the next month and make a difference?
Zinkie: Trea Turner is my pick. A.J. Reed and Jose Peraza are also possibilities.
@jaredstout46: Who wins a trade of Giancarlo Stanton for Jake Arrieta and Nomar Mazara?
Zinkie: It is close, but I will take the Arrieta side. He has been so spectacular.
@soconn11: Which starter should I drop -- J.A. Happ, Derek Holland, or Liam Hendriks?
Zinkie: Drop Holland. Hendriks is very reliable. And I believe in Happ's strong start more than Holland's.
@thegoldrushh: I lost Carlos Carrasco and Raisel Iglesias to injury. Are there any under-the-radar starters who could come at a low price?
Zinkie: Jesse Hahn and Josh Tomlin are good options. They are likely sitting on waivers in your league.
@ljdobson9: Is Luis Severino worth adding despite his struggles?
Zinkie: It depends on which player you would need to drop. But overall, I would be happy to stash him on my bench.
@KevinWiles: Who do you best like out of Park, Curtis Granderson, Nick Castellanos, Brett Lawrie, Martin Prado and Gerardo Parra?
Zinkie: I would add Granderson. He was very productive in 2015. I expect him to have a solid season.
@Jlch2185: I'm losing patience with Jacoby Ellsbury and Adam Jones. Should I drop either for Drury, Jackie Bradley Jr. or Prado?
Zinkie: Stick with your veterans. Give them a couple more weeks before dropping them. You can feel free to bench them for now.
@ItsSalJr: Should I keep Evan Longoria, or should I drop him for either Jake Lamb or Drury?
Zinkie: Stick with Longoria. Once he heats up, he should be much more valuable than Lamb or Drury.
@Michael_AskewJr: Of the top pitching prospects, which one would you grab if dropping Berrios?
Zinkie: Stick with Berrios, and give him a few starts to prove himself. He is a top pitching prospect.
@zachhajas: Would you rather own Alex Gordon or Bradley?
Zinkie: Gordon. Bradley has limited potential from the bottom of the lineup. I expect Gordon to get it going soon.
@BoldPhilly: Who do I grab for stolen bases to replace Dee Gordon?
Zinkie: If you have room in the outfield, Jarrod Dyson is a great option.
@Chris__Burns: I'm thinking about dropping Jason Heyward. Should I stick with him a little longer, hoping he heats up?
Zinkie: Definitely stick with him. He could be really productive as the Cubs' No. 2 hitter if he heats up.
@jtpaul23: Should I stash Blake Snell or Robert Stephenson?
Zinkie: Snell, for sure. He has a higher ceiling than Stephenson.
@einstein2u: Please rank Berrios, Kevin Gausman, Carlos Rodon, Aaron Sanchez and Eduardo Rodriguez.
Zinkie: Rodon, Sanchez, Berrios, Gausman, Rodriguez.
@al9x1: Should I pick up Gausman, Rick Porcello or Tanner Roark?
Zinkie: Porcello. His strong start to 2016 cannot be ignored.
@billy51300: What would be an appropriate return for Arrieta?
Zinkie: A top 10 hitter. If drafting today, Arrieta would have to go in Round 1.
