Cubs manager David Ross said Saturday that Wesneski will likely replace Justin Steele (forearm) in the rotation while Steele is on the 15-day injured list, Maddie Lee of the Chicago Sun-Times reports.
Ross believes Steele will miss only two turns through the rotation. Wesneski opened the season as a starter for the Cubs, but the right-hander struggled to a 5.03 ERA before being demoted to Triple-A Iowa in mid-May. Wesneski has shown the ability to miss bats, but he'll be a risky fantasy streamer while he's a member of the rotation, and he doesn't look as though he'll be in line for a long-term appointment.
