The A's catcher, who has been sidelined since the end of July, was not anticipated to be ready in time to appear on the postseason roster, should the A's clinch a playoff spot, as expected. But on Thursday, Melvin wasn't ruling out such a possibility.
"Three or four days ago, I didn't think there was a chance where maybe now there is a chance," Melvin said. "He really turned the corner three or four days ago. Now that he's out here doing baseball activity and taking batting practice, the next step is to get some at-bats, and if that's the case, you never know."
At the very least, having Jaso healthy could give the A's a lefty-swinging backup option, in the unlikely event Stephen Vogt goes down to injury at some point. Vogt and Derek Norris are likely to be the catchers appointed to the postseason roster.
