TORONTO -- Thad Weber joined the Blue Jays on Saturday, coming up to replace the recently optioned Sean Nolin. Weber, 28, was claimed off waivers from the Padres last Sunday.
"He's supposed to start down there [in Buffalo] Sunday, so he'll throw some innings here," manager John Gibbons said of the move.
Weber has only pitched 13 innings in his Major League career, including stops in San Diego and Detroit, but has a 2.00 ERA with five hits, five walks and six strikeouts in nine innings on the mound this season as a reliever.
The Blue Jays haven't confirmed Wednesday's starter in Atlanta, but it may be Weber or Ramon Ortiz, who started last Tuesday.
"It could be one of those two," Gibbons said.
However, don't expect Josh Johnson to be pushed to the Majors from his rehab outings to make that start. Johnson threw 68 pitches Saturday for Triple-A Buffalo, and the Blue Jays would prefer to take their time with the righty.
"We want to make sure he's good and ready," Gibbons said. "We did that with [Chad] Jenkins a little bit the first time, but Josh is different. We need him to help carry us the rest of the year, so we have to make sure he's good and ready."
