Weathers made his most recent appearance out of the bullpen, striking out one over a scoreless inning in Wednesday's 8-3 loss to the Diamondbacks.
Weathers was dropped from the rotation in advance of Jake Arrieta's return from the 10-day injured list Friday to take over the No. 5 starter role. After a promising start to the season, Weathers faltered badly in his final six turns through the rotation, giving up 31 total earned runs in 20.2 innings.
