The Tigers have agreed to a $3.1 million contract with right-hander Rick Porcello and a $1.1 million deal with left-hander Phil Coke.
The agreements avoided the two sides to avoid arbitration.
Porcello started 31 games last season for Detroit, going 14-9 with a 4.75 ERA in a career-high 182 innings.
Coke began last year in the starting rotation but moved back to the bullpen around midseason. He finished 3-9 with a 4.47 ERA in 48 appearances.
