With the window of contention still wide open, the Indians locked up one of their key bullpen pieces on Tuesday.

The club has signed relief pitcher Dan Otero to a two-year extension, after both sides previously avoided arbitration with a one-year deal earlier this week. The new contract keeps Otero in Cleveland through at least the 2019 season, and also includes a team option for 2020.

Acquired from the Philadelphia Phillies before the 2016 season, the 32-year-old Otero has gone 8-1 with a 2.14 ERA over 114 appearances with the Tribe. He also put up a 2.70 ERA during the 2016 playoffs, but was controversially left off last season's postseason roster.

Financial details of the contract have not yet been made public. Otero made just over $1 million in 2017.
