MLB.com fantasy expert Fred Zinkie fielded questions from fans during a live Twitter chat (@Fantasy411) on Monday. Read through the best of the Q&A below. Questions and answers have been edited for clarity.
@MAS8823: Should I buy low on Billy Hamilton in hopes of him figuring out how to get on base?
Fred Zinkie: I would want a major discount. I'm not optimistic that he can turn it around at the dish.
@thegoldrushh: What are your thoughts on Matt Wieters? Are there other catchers to look out for with potential?
Zinkie: I expect Wieters to improve as the season progresses. Yasmani Grandal is someone else you can consider.
@PeteTheHeatMMA: Should I drop Grandal or Stephen Vogt for Jarrod Saltalamacchia?
Zinkie: You should keep your current pairing, as they should compile more counting stats this season.
@whosethattt: In a dynasty league, should I trade Jose Fernandez and Mookie Betts for Bryce Harper?
Zinkie: It's a lot to pay, but Harper is worth it. Make the trade.
@tonybkny: Which fantasy backup is worth a spot on my bench -- Aledmys Diaz or Javier Baez?
Zinkie: I would rather own Diaz, as he has a looked really good since making his debut.
@bails85: Should I drop David Peralta or Gerardo Parra for Jarrod Dyson?
Zinkie: You should keep your current players. Dyson will contribute steals, but not much else.
@Norcallie76: Should I drop Brandon Finnegan for Tanner Roark in my head-to-head points league?
Zinkie: You can make that switch. I don't expect great things from Roark, but he is better supported than Finnegan.
@samardzija32: I need outfield production. Please name an under-the-radar contributor.
Zinkie: Melvin Upton Jr. has been stuffing the stat sheet in recent games.
@ThaBasementBoys: Chris Carter is off to a good start. How do you think he will fare this season?
Zinkie: I expect him to hit 30 homers and drive in 75 runs. I also expect a batting average below .250.
@billy51300: What would be an appropriate return in a trade involving Jake Arrieta?
Zinkie: You would need to get one of the best five or six best hitters.
@BaseballNStuff: Should I stash Javier Baez or Trea Turner in a keeper league at middle infield?
Zinkie: I would stash Turner, as he could make a major impact once he gets the call in 2016.
@scott_peterson4: Please pick one for the rest of the season -- Khris Davis, Carlos Santana or Jorge Soler.
Zinkie: I will take Santana. I'm not especially optimistic about the other two players.
@real_wes_trunk: I have many good pitchers, but I am weak in the outfield. Should I trade Steven Matz for Yasmany Tomas?
Zinkie: You shouldn't make that trade. You can't make a lopsided trade due to need at this point in the year. Use the waiver wire to fill your needs.
@nmach10: Who is the better prospect to own -- Lucas Giolito or Tyler Glasnow?
Zinkie: I slightly prefer Glasnow. But I expect Jose Berrios to make his Major League debut before Giolito or Glasnow.
@Jsports_47: With Carlos Carrasco going on the disabled list, which starter should I pick up -- Mat Latos, Edinson Volquez, Jaime Garcia, Ian Kennedy or Gio Gonzalez?
Zinkie: You have multiple great options. I would take Garcia. He should serve you well while Carrasco is out.
@jorash17: I need to pick one of these starting outfielders -- Stephen Piscotty, Steven Souza Jr., Odubel Herrera or Michael Conforto.
Zinkie: Definitely go with Conforto. He can make a major impact this season.
@BigMelch24: Should I trade both Buster Posey and Starling Marte to get Noah Syndergaard?
Zinkie: No, that is too much to trade. Syndergaard is a top-tier starter for sure. But you can't trade two top-tier hitters for him.
@ljdobson9: Can I drop Adam Wainwright?
Zinkie: I think that it is too early to drop him. But he can be benched for now. Give him one or two more starts.
@Saulty22: Which pitcher can I trust out of Rick Porcello, Jonathon Niese, Marco Estrada, Roark, Rich Hill, Kendall Graveman and Derek Holland?
Zinkie: From that group, I trust Estrada. Hill likely has the most potential, but he can really hurt your WHIP.
@THRASHERNAGAOKA: Diaz has played very well. Will he still start when Jhonny Peralta comes back?
Zinkie: I can't envision Peralta as a bench player. But July is a long way away. Enjoy Diaz for now, and we can evaluate his options in June.
@alexruibal: Should I drop Joe Ross and add Blake Snell?
Zinkie: I like Snell as a prospect, but you can't drop Ross for him. Ross is also a talented young starter, and he already has a permanent rotation spot.
@rostrows: Is Tyler White worth keeping or should I try to trade him while he's still hot?
Zinkie: This is definitely a good time to try to trade him. He is unlikely to maintain his current power pace.
