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.
@BigWienke: Should I drop Jackie Bradley Jr. and pick up Michael Conforto?
Fred Zinkie: Yes, you can make that switch. Conforto should be owned in virtually every league.
@GlennWarner13: Should I trade Carlos Martinez for Dylan Bundy?
Zinkie: You should likely stay patient and stick with Martinez for now.
@GeorgeBrownSTL: Is Jonathan Lucroy still worthy of our patience?
Zinkie: I believe that Lucroy is worth your patience. He could be a top-3 catcher once he heats up.
@Locke_4: Should I trade Aaron Judge for Kyle Schwarber? I'm looking to trade him for a star who is off to a slow start.
Zinkie: No, you shouldn't make that deal. Schwarber is not the caliber of player you're looking for. It would need to be a slow starter who went in the initial three rounds of your draft.

@alexfarkas13: Please rank Manuel Margot, Jose Bautista, Jacoby Ellsbury, Ian Desmond, Chris Owings and Bradley.
Zinkie: Desmond, Owings, Ellsbury, Bradley, Margot and Bautista.
@illkeeptrekkin: Who is the closer to own in Washington?
Zinkie: My guess is that no reliever on its current roster gets more than 10 saves the rest of the way. If I was to own one, it would be Koda Glover.
@BlakeEMeakin: Can I give up on Carlos Gonzalez? Also, is Aaron Hicks for real?
Zinkie: My answer is "no" to both questions. CarGo should come around soon. Hicks can be used for a short time in deep leagues.
@StunningSteveK: Should I drop Todd Frazier for Joey Gallo?
Zinkie: Keep Frazier. He hit 104 homers across 2014-16, and he has dealt with poor batted-ball luck this season.
@BQuick52: Which two pitchers should I add out of Chris Tillman, Kendall Graveman, Mike Leake and Taijuan Walker?
Zinkie: Add Leake (pitching well) and Walker (most potential in that group).
@StvnSmth: Would you rather own: Travis Shaw or Ryon Healy?
Zinkie: I will take Shaw. I believe his power is safer.
@Matt_The_Stud: Is it time to sell high on Yonder Alonso, Avisail Garcia or Gerardo Parra?
Zinkie: My guess is that it's too early to sell high on Alonso and too late on Parra. The sell-high window is open on Garcia.

@TylerRose4: Would you rather own Alonso or Ender Inciarte?
Zinkie: I will take Inciarte. I like his multidimensional skill set.
@STANLEY73: Should I pick up Chris Tillman?
Zinkie: Tillman should be added in 12-team leagues. He can stay on waivers in 10-team formats.
@aablack232: Which shortstop do you like better: Zack Cozart or Elvis Andrus?
Zinkie: Definitely Andrus. He is a solid source of batting average and steals.
@KingLuke21: Should I drop Adam Wainwright, or is he going to turn his season around?
Zinkie: Yes, Wainwright can be dropped in most mixed leagues.
@Glolivelaughluv: Should I drop Gregory Polanco for one of Hicks, Ellsbury, Kevin Pillar, Brett Gardner or Aaron Altherr?
Zinkie: You can drop Polanco for Ellsbury, which will likely start a season-long chain of riding the hot hand.
@EzPolizzi_21: Would you rather own Aaron Altherr or Michael Taylor?
Zinkie: I'll take Altherr. I believe he has better skills than Taylor.

@Jlch2185: Please rank Sonny Gray, Robbie Ray, Julio Urias, Eduardo Rodriguez and Amir Garrett.
Zinkie: Ray, Urias, Rodriguez, Gray, Garrett.
@GJennings19: Should I trade Yasmany Tomas for J.D. Martinez?
Zinkie: For sure. Martinez should soon be one of the most valuable fantasy hitters.
@MikeEvoX: Should I drop Zach Britton for Rich Hill?
Zinkie: You should definitely keep Britton. Try to cover his absence by trading for Brad Brach.
@luke4msu: Can I go ahead and drop Bautista?
Zinkie: I have run out of patience with Bautista. You can drop in 12-team and 10-team leagues.
@jwp1006: Should I trade Clayton Kershaw for Carlos Carrasco and Johnny Cueto?
Zinkie: You should keep Kershaw. His value is so much higher than that of any other starter.
@enniscurtis: Is Hicks legit as a five-category stud?
Zinkie: I'm not yet sold on Hicks. You can use him for now, but don't expect him to help you all season.
