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.
@rangersfantasyb: Should I drop Kole Calhoun and add someone that can help me in categories I need, such as stolen bases?
Zinkie: We have reached the point in the season when you can makes moves like that. Focus on the categories you need.
@rhj_24324: Should I drop Brian McCann for Gary Sanchez?
Zinkie: I would stick with McCann, but it is close. Sanchez could be a Top 12 catcher down the stretch. In a daily transaction league, it would be nice to own both.
@LyndonBryanton: Please rank Jonathan Schoop, Willson Contreras, Jose Ramirez and Rajai Davis.
Zinkie: Schoop, Ramirez, Davis, Contreras. If you need power, grab Schoop. If you need speed, take Davis. If you want balance, opt for Ramirez.
@thealexmoretto: Will Taijuan Walker be back up in time to help my team down the stretch, or should I drop him?
Zinkie: He will likely be back, but he may not help you. You can drop him if there is someone on waivers you really want.
@__MeatBall: Should I drop Trevor Bauer or Matt Shoemaker for Braden Shipley this week?
Zinkie: If you are thinking only about this week, you can drop Bauer for Shipley. In the long run, I would rather have Bauer.
@matt3pt: My team has multiple pitcher injuries. Please name some starters that I can add.
Zinkie: Depending on your league size, you can grab Blake Snell, Robbie Ray, Luke Weaver, David Phelps or Dan Straily.
@DN1CE23: Would you rather own Yulieski Gurriel or Alex Bregman.
Zinkie: I will take Bregman. He is emerging from a slow start. He is very talented, and I expect a big finish.
@MarkStormbro: Please rank Weaver, Matt Boyd, Shoemaker, Phelps, Ray and Chase Anderson.
Zinkie: Shoemaker, Phelps, Ray, Weaver, Boyd, Anderson.
@rangersfantasyb: Who are the top waiver-wire pickups for stolen bases?
Zinkie: Look for Travis Jankowski. Aaron Altherr is another option to pick up some steals down the stretch. Paulo Orlando is a deep-league option.
@mbunin7: Would you rather own Lance McCullers or Danny Duffy long term? And, would you rather own Tom Koehler or Ray for the rest of the season?
Zinkie: I'll take Duffy and Ray.
@Mozzay_11: Would you rather own Andrew McCutchen or Ian Desmond?
Zinkie: Even though he has tailed off a bit, Desmond is still my pick.
@STANLEY73: I lost Adam Conley to the disabled list. Who should I grab out of Koehler, James Paxton and Shipley?
Zinkie: Go with Paxton.
@Mitch_Sirota18: Should I start Koehler or Joe Musgrove this week?
Zinkie: Musgrove. He has to stay in all lineups until he has a poor start.
@pinstripexpert: Would you trade Aaron Judge for Joey Gallo in a mixed league?
Zinkie: No, I would keep Judge. He could fare quite well down the stretch.
@bubbacroft8: Please rank Paxton, Boyd, Ervin Santana and Jeremy Hellickson.
Zinkie: Hellickson, Santana, Paxton, Boyd.
@dnots777: Would you rather own McCann or Cameron Rupp?
Zinkie: I'll take McCann, but it is getting close. Ideally, you should add Rupp and trade McCann.
@DruVeritas: Would you rather own David Dahl or Adam Duvall?
Zinkie: Dahl. He playing well in a great situation.
@D_LloydZz: Please name a pitching prospect that may soon reach the Majors.
Zinkie: Josh Hader could get a chance with the Brewers down the stretch.
@dnots777: Is Wade Davis worth stashing?
Zinkie: Definitely, if you need saves.
@FlynnWingate: Do you prefer Tyler Naquin or Jankowski going forward?
Zinkie: Jankowski, assuming that steals have value for you.
@afrost32: Should I drop Sanchez for Weaver?
Zinkie: I would rather own Sanchez, assuming that you have use for a catcher.
@perez_raudy: Is it time to pick up A.J. Pollock?
Zinkie: Yes, he should be added in most leagues.
@sritsema11: Should I drop Hunter Pence for one of the Yankees rookies?
Zinkie: No, I prefer Pence to Sanchez, Judge or Tyler Austin.
@James26Wang: Should I drop Hernan Perez for Judge?
Zinkie: It depends on your needs. Keep Perez if you value steals. Grab Judge if you need homers.
