Cubs select Trayce Thompson after placing Jason Heyward on concussion IL

The Cubs announced they’ve selected outfielder Trayce Thompson to the big league roster. Jason Heyward is landing on the seven-day concussion injured list in a corresponding move. To open space on the 40-man roster, Chicago transferred outfielder Michael Hermosillo from the 10-day to the 60-day injured list.

Thompson is back in the big leagues for the first time in three years. The right-handed hitter broke in with the White Sox in 2015 and saw some MLB time in each of the following three seasons, with his biggest workload coming with the 2016 Dodgers. Thompson hit for a fair amount of power and can cover all three outfield spots, but his overall productivity was limited by swing-and-miss issues. In 589 big league plate appearances, he owns a .206/.276/.389 mark with 22 home runs but an alarming 28% strikeout rate.

He’s split the 2021 season between the Triple-A affiliates of the D-Backs and Cubs, spending most of the campaign with Chicago’s top farm team in Iowa. Thompson has popped 21 round trippers in 358 plate appearances there but continued to punch out quite a bit. He owns a .233/.344/.492 line with a 32.4% strikeout rate with Iowa this season.
