Welcome back RotoBallers, to another edition of the fantasy baseball waiver wire rankings for Week 21 -- August 14 through August 20. There are just over 45 days left of the regular season to be played as fantasy managers scout the waiver wire to help them add pieces for a championship run.
More top prospects are being called up to the big leagues, and some are producing for fantasy managers immediately. The Mariners called up top pitching prospect Emerson Hancock earlier in the week, who made his MLB debut on Wednesday. Top prospects such as Masyn Winn, Colt Keith, Matt Mervis, Ceddanne Rafaela, and Pete Crow-Armstrong patiently await the call to the big leagues.
Notable injury notes include Shane McClanahan, who was placed on the 60-day injured list Saturday, officially ending his season. Christian Encarnacion-Strand (hand), Mookie Betts (illness), Luis Robert Jr. (finger), and Francisco Lindor (side) are considered day-to-day. Reinforcements are coming as Michael Wacha (shoulder) and Charlie Blackmon (hand) are close to returning to action. The ball is flying out of the yard as offenses are heating up. We are here to help sort it all out with our latest waiver wire rankings article.
