He's not eligible to come off the DL until May 5, but Hanigan is hoping to do more in the coming days.
"It's coming along, rest is making everything slowly get better," Hanigan said before the series opener in Washington on Thursday. "My side feels pretty good; my thumb's on its way. I'm going to give it a couple more days just to make sure, and then start doing some stuff."
Hanigan will hope to fare better once he returns to the field, as the catcher had gotten off to a very slow start in 2013, batting .079 (3-for-38).
