Former Detroit Tigers pitcher Francisco Liriano has signed a minor-league deal with the Pittsburgh Pirates.

Reporters Ken Rosenthal and Joel Sherman reported the news Wednesday afternoon. The deal will be worth $1.8 million if Liriano makes the club, and he can earn another $1.5 million in incentives, according to Robert Murray.

Liriano was one of four Tigers who became a Major League free agent after the 2018 season. Victor Martinez and Jarrod Saltalamacchia have retired. Shortstop Jose Iglesias remains unsigned.

Liriano, 35, pitched for the Pirates from 2013 to 2016.

Liriano signed with the Tigers last February at the start of spring training. He went 5-12 with a 4.58 ERA in 2018, striking out 110 and walking 73 in 133 2/3 innings.

The Tigers have signed two free-agent pitchers to Major League deals this winter -- right-hander Tyson Ross and left-hander Matt Moore.
