They likely know who is interested but the timing of his dfa was no accident. They’ll wait until the deadline is over so they know he isn’t needed as part of a deadline trade.
Kemp just traded for Maldonado https://www.mlbtraderumors.com/2019/07/astros-acquire-martin-maldonado.html
I’m very happy for Kemp... And the Astros are getting catching depth, good move.... I’m still disappointed that Stassi has not been able to get his offense going. Stassi’s OPS this season was .446! Talk about a huge black hole in the lineup. His defense is good/decent, but geesh that bat was beyond pitiful.
