The Tigers have traded Nick Castellanos to the Cubs.
Castellanos was in the Tigers lineup at 4:05 p.m., but was pulled off the field as Jordy Mercer took his spot on-deck.
In return, the Cubs sent RHP Paul Richan and RHP Alex Lange to Detroit. The Tigers also sent cash to Chicago, to pay part of Castellanos' remaining salary.
“Maximizing our pitching depth is something that’s important to the long-term success of our organization,” Tigers general manager Al Avila said.
Richan is a 22-year-old pitcher, ranked 16th in the Cubs system. He's a "polished, overstuffed starter who could advance quickly," according to MLB.com.
Lange was the 30th overall pick out of LSU in the 2017 Draft. He was ranked 23rd in Chicago's system.
The 27-year-old is hitting .273 with 11 home runs and 37 RBI this season.
“Richan is a true competitor on the mound, and knows how to pitch with his arsenal better than most his age. His solid makeup and performance on the field shows us that there’s a good future for him in our organization. Using a short but effective arm action, Lange shows great run and life on his fastball, complemented by solid bite on his offspeed pitches. Both these players are welcome additions to our player development system," Avila said.
