The Pirates have signed free-agent left-hander Francisco Liriano, MLB Network insider Ken Rosenthal reported Monday, with The Athletic adding that it's a Minor League deal worth $1.8 million plus incentives if he makes the roster. The club has not commented on the reports.

Liriano, a 13-year veteran, is no stranger to Pittsburgh. He signed with the Pirates as a free agent prior to the 2013 season and then re-signed the next offseason, remaining with the club until he was traded to the Blue Jays on Aug. 1, 2016. Liriano made 107 starts in a Bucs uniform, going 41-36 with a 3.67 ERA.

When the Pirates snapped a long playoff drought in 2013, Liriano started and won the National League Wild Card Game against the Reds, allowing just one run over seven innings. He also pitched well in the club's win over the Cardinals in Game 3 of that year's NL Division Series.
