Bryce Harper cleared waivers last year. Elite players can and do clear revocable waivers in August. They clear for a number of reasons. Sometimes they'll clear because yes, the team cannot afford the contract and they know that they'll simply be pulled back anyway. I'd go as far as to say Scherzer probably clears, just as Verlander did last year. I think people misunderstand how different revocable waivers are from regular waivers and would be shocked at how many players clear. The sheer number of players placed on waivers in August is an enormous list and claims are usually strategic -- either to block a rival contender from a player they might want or from a genuine desire to try to acquire a player. They're not even supposed to leak the names that do and yet we hear about many high profile names yearly. Players like Harper clear waivers every year because they are only on waivers as a formality. You can't sneak a trade for a player like Scherzer through that way, not least because if you are shopping Scherzer you're going to let teams know and not just work out a sweetheart deal with a secret bidder. Verlander cleared because he was still owed a lot of money and was looking fairly mediocre in Detroit. He only reasserted himself as an ace pitcher after the trade.
