How did Astudillo have a positive WPA when he made a couple of poor plays? He was thrown out at home because he forgot that he's a tortuga who thinks he's a hare and he didn't run hard. And then he gave up a run on the double steal by throwing to second and everyone was safe. I thought in that situation you're supposed to just give up the stolen base to protect the plate.
I don't believe either of those plays are considered by WPA.
