The Cubs announced a trio of roster moves, including Jason Heyward’s activation from the 10-day injured list.  (The Athletic’s Meghan Montemurro was among those to report the news.)  Chicago also designated outfielder Nick Martini for assignment, thus opening up a 40-man roster spot for right-hander Dakota Chalmers, who was claimed off waivers from the Twins.  Right-hander Cory Abbott is also being called up from Triple-A to make his big league debut, FanSided’s Robert Murray reports (via Twitter)

A left hamstring strain forced Heyward to the IL on May 20, and the injury hiatus could allow the veteran outfielder something of a reset of his season.  Heyward has hit just .183/.254/.341 over his first 138 plate appearances, an unfortunate slow start after the strong numbers he posted during the 2020 season.  Through Heyward’s tenure in Wrigleyville (he’s in the sixth year of an eight-year, $184MM contract) has been marked by a lack of offensive production, Heyward was one of the team’s best bats in 2020, hitting .265/.392/.456 with six homers over 181 PA.
