Schoop and Cron spent the 2018 season as teammates on the division-rival Minnesota Twins.
While Schoop was slated for free agency following the 2019 season, Cron was eligible for arbitration. However, the Twins non-tendered the slugger, who subsequently hit the open market.
Schoop, 28, hit .256/.304/.473 with 23 homers and 23 doubles over 121 games last season.
The former All-Star is slated to be the everyday second baseman for the Tigers, who deployed Ronny Rodriguez, Gordon Beckham, Harold Castro, and Josh Harrison at the position last year. Detroit ranked worst in baseball at production from second base, according to FanGraphs’ WAR.
Meanwhile, Cron posted a .253/.311/.469 slash line with 25 homers and 24 doubles. The 29-year-old is one season removed from a 30-homer campaign with the Tampa Bay Rays. He’ll compete for at-bats with incumbent first baseman Brandon Dixon, who authored a .725 OPS last year.
