Andrelton Simmons’ return to the Chicago Cubs couldn’t have come at a better time. Simmons endured a frustrating rehab from right shoulder soreness, something he never had experienced in his 11-year big-league career before it sidelined him during spring training. But with second baseman Nick Madrigal already on the injured list, shortstop Nico Hoerner’s move to the IL on Sunday struck a big blow to the Cubs’ middle infield depth while costing them one of their best defensive players. The Cubs activated Simmons from the IL as the corresponding move Sunday, and he entered as a defensive replacement at shortstop in the ninth inning and recorded the final out against the Arizona Diamondbacks. Simmons — who started at short in Monday’s series-opening 9-0 victory against the Pittsburgh Pirates at Wrigley Field — indicated his shoulder feels pretty good but still has room to improve. He didn’t need to wait long to collect his first hit as a Cub.
