The Chicago Cubs’ long-term outlook on right-hander Hayden Wesneski hasn’t changed. They believe in his ability to be a big-league starter and potentially an impact arm in their rotation down the line. But the Cubs need more out of their struggling bullpen and are looking to Wesneski to bolster it. They recalled the 25-year-old from Triple-A Iowa before Tuesday’s 2-1 victory against the Tampa Bay Rays and optioned right-hander Michael Rucker. Manager David Ross isn’t defining a role for Wesneski in the bullpen.
