Jaso will start in right field and bat sixth Tuesday against the Cubs.

EDGE Analysis

Pirates manager Clint Hurdle hasn't named a primary replacement in right field for the injured Gregory Polanco (hamstring) and Adam Frazier (hamstring), but it appears Jaso could be the leading candidate for regular starts at the position against right-handed pitching. He'll start in right for the third time in five games Tuesday after the righty-hitting Jose Osuna manned the position in the series opener Monday, when lefty Mike Montgomery took the hill for the Cubs.
