Weathers threw two innings in a simulated game Thursday, AJ Cassavell of MLB.com reports.
Weathers continued his work to stretch out as a starter this spring while pitching against Eric Hosmer, Manny Machado and Tommy Pham. He reportedly generated several swings and misses without allowing any hard contact. Weathers isn't likely to start the season in the Padres' rotation, though it can reasonably be expected that he will make a significant impact with the club during the regular season.
