@MarkAPier: Is it time to drop Bud Norris for Cam Bedrosian?
Fred Zinkie: Yes, it is. Norris' time as closer seems to be over.

@ChrisYohe1: Please rank Kevin Gausman, Carlos Rodon, and Jeff Samardzija.
Zinkie: Rodon, Samardzija, Gausman.
@tahamufti1: Is Rhys Hoskins a must-add player?
Zinkie: Not quite, but pretty close. In most 10-team leagues, there is a team who could use him.
@silaPssoR: Please pick a player to drop out of Manuel Margot, Cameron Maybin, David Peralta, Tim Beckham or Chris Davis.
Zinkie: If you don't really need steals, drop Maybin. Otherwise, drop Peralta.
@itsallbird: Please rank Matt Wieters, Jonathan Lucroy, Evan Gattis and Alex Avila.
Zinkie: Wieters, Gattis, Lucroy, Avila.
@KevinJE333: Which player should I keep in a keeper league out of Zack Godley, German Marquez and Mike Clevinger?
Zinkie: Keep Godley. He has been very good and consistent this season.
@TheRandallPink: Which rookie do you like out of Hoskins, Amed Rosario, or Yoan Moncada?
Zinkie: I'll rank them Moncada, Rosario, Hoskins.

@DaTeufelShuffle: Who do you like more, Todd Frazier or C.J. Cron?
Zinkie: Go with Frazier. Cron has potential, but he has teased us before.
@juliantharmsen: Do you prefer Jonathan Villar or Ryan McMahon?
Zinkie: I'll take Villar. I don't expect McMahon to play often.
@sritsema11: Is it OK to drop Sam Dyson since Mark Melancon is back?
Zinkie: I wouldn't drop Dyson yet. You can drop him in a week or two if Melancon reclaims the closer's role.
@TerminiMike: Should I pick up Brad Peacock or Jerad Eickhoff?
Zinkie: You should add Peacock, who should get more run support.
@nmach10: Should I drop Jose Berrios for J.A. Happ?
Zinkie: Yes, Happ has been quite consistent this summer.

@fanbball34: Should I hold Willson Contreras? I also own Noah Syndergaard, Chase Anderson, James Paxton and Lance McCullers Jr.
Zinkie: Hold Contreras. Drop Anderson if you are stuck for roster room.
@lundph01: Would you rather have Davis or Lucas Duda?
Zinkie: I'll take Davis, but I'm not excited about either option.
@RichieRR1: Should I drop Dinelson Lamet, Jake Odorizzi, Jose Urena, Parker Bridwell, Adam Conley or Eickhoff?
Zinkie: You can drop Conley.
@jscatalano: Who would you drop out of Jose Bautista, Avisail Garcia and Maybin?
Zinkie: My pick is to drop Garcia.
@RichieRR1: Is Rafael Devers the new David Ortiz?
Zinkie: He has a long way to go! But he's off to a solid start. He should be owned in almost all leagues.

@bubbacroft8: Please rank Corey Dickerson, Melky Cabrera, Whit Merrifield and Carlos Santana.
Zinkie: Merrifield, Cabrera, Dickerson, Santana.
@FootbalFantasyy: Should I add Neil Walker or Brandon Phillips?
Zinkie: Go with Walker. He could have some success in Milwaukee.
@pierretong: How long do you stick with prospects before dropping them?
Zinkie: I like to give them at least three weeks.
@BGPN88: Should I drop Mike Leake for Lamet?
Zinkie: You can make that switch. Leake has limited upside. We may have seen the best of him for this season.
@jdmontenegro7: Please rank these pitchers Cole Hamels, Alex Cobb and Sonny Gray.
Zinkie: Hamels, Gray, Cobb.
@jolu4u: Who should be the closer for the White Sox now?
Zinkie: Maybe Jake Petricka. Overall, it's a situation to avoid in fantasy leagues.
