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.
@Schumer21: What should I do with Ervin Santana and Jason Vargas?
Zinkie: Continue to use Vargas for most matchups. But be selective about using Santana. Don't drop either one yet.

@JosephC74359195: Who should I drop out of Jose Bautista, Jackie Bradley Jr. or Yoan Moncada?
Zinkie: Drop Bautista. He isn't hitting for average or producing steals and RBIs.
@nmach10: Danny Salazar looked good against Toronto in his first outing. Should I pick him up?
Zinkie: I want to see another start. The Blue Jays have really been slumping of late.
@halfway_cook: What should I do with Jose Cabrera? Should I trade him?
Zinkie: Cabrera's trade value is likely too low at this point. You can bench him for now if you have other good options.
@D_Barrett18: Who will have a better second half of the season, Starling Marte or Yoenis Cespedes?
Zinkie: Marte. Especially in roto formats.

@azito23: Should I drop Lorenzo Cain for one of Nick Williams, Cory Spangenberg, Odubel Herrera or David Peralta?
Zinkie: I would stick with Cain over those options.
@tyler_brodeur20: When do you think Amed Rosario is going to get the call?
Zinkie: Early August.
@DarrenHill221: Should I drop Steven Matz for Reynaldo Lopez, in hopes that Lopez will get promoted?
Zinkie: I wouldn't make that switch. Lopez could have difficult matchups and may not thrive right away.
@davesull4: Which pitcher should I drop out of Kyle Hendricks, Gerrit Cole, Cole Hamels and Sonny Gray?
Zinkie: Tough call, but getting rid of Hamels is my pick.
@DylansSports1: What should I do with Jacob Faria?
Zinkie: You should continue to start Faria. Overall, he has been very solid.
@AnthonyBiondo3: Please rank Alex Bregman, Ian Happ and Nick Williams.
Zinkie: Bregman, Happ, Williams.
@Z_Nelsy: Should Paul DeJong be added in all leagues?
Zinkie: Pretty much. Definitely in all roto leagues.

@JosephC74359195: Which pitcher should I drop out of Jose Berrios, Jimmy Nelson or Danny Salazar?
Zinkie: Salazar. Berrios has terrific skills and Nelson has been excellent this year.
@tickster24: Please rank Nomar Mazara, Carlos Gomez, Hunter Renfroe, Jason Heyward, Kole Calhoun, Stephen Piscotty.
Zinkie: Mazara, Calhoun, Gomez, Renfroe, Piscotty, Heyward.
@alfredo_gc: Do you prefer Yoan Moncada or Rafael Devers?
Zinkie: I'll take Moncada in roto and Devers in points leagues.
@jjthorn17: Would you rather have Yuli Gurriel or Rafael Devers?
Zinkie: Gurriel is safer. If Gurriel is the worst hitter on your team, I'll take Devers for the upside. If you have to depend on one, it's Gurriel.
@ReverendAdam2: Who should I start, Tyler Clippard or Anthony Swarzak?
Zinkie: Clippard, but keep your expectations low.

@acutonix: Should I drop Gerardo Parra, Mike Leake or Alex Meyer?
Zinkie: Drop Meyer.
@statcher5: Do you prefer Alex Bregman or Rafael Devers?
Zinkie: Bregman. But it's very close, and I am higher on Bregman than most others are.
@Beeweeze: Please rank Blake Snell, Seth Lugo, Trevor Cahill and Brent Suter.
Zinkie: Cahill, Lugo, Suter, Snell.
@sowrongitsdyce: Do you prefer Addison Russell or Whit Merrifield?
Zinkie: Definitely Merrifield.
@qaqlqeqxq: Please rank Aaron Sanchez, Rick Porcello, Eduardo Rodriguez and Jake Odorizzi.
Zinkie: Rodriguez, Porcello, Odorizzi, Sanchez.
