At higher salary, probably, than the Astros will be paying Gregerson. And for roughly similar reliable results, but maybe Beane likes him better (Fangraphs projection for him is a little better too). EIther that or Gregerson simply would not consider re-signing with the A's, which I suppose a player might do if he doesn't like the ultra-small market dynamic there. Kind of a loss for Beane, all told, considering he gave up Seth Smith to get Gregerson, whom the Padres flipped for starter prospect Brandon Maurer. With perfect hindsight, and ignoring the 2014 contributions of the players, Beane could have acquired Maurer, and still had the salary room to obtain the Yankee Nat Clippard.
