The Cincinnati Reds activated outfielder Austin Hays, second baseman Matt McLain and reliever Alexis Diaz from the injured list on Tuesday.

Hays (calf) and McLain (hamstring) were on the 10-day IL and Diaz (hamstring) was on the 15-day IL.

Hays, 29, has yet to make his Reds debut. The former All-Star split last season with the Baltimore Orioles and Philadelphia Phillies and signed a one-year, $5 million deal with the Reds in January.

McLain, 25, has appeared in eight games this season for Cincinnati, batting .214 with three homers and five RBIs.

Diaz, 28, has yet to play for the Reds this season after serving as their closer the past two years. The right-hander made the All-Star team and finished with 37 saves in 2023.

The Reds optioned outfielder Jacob Hurtubise and infielder Noelvi Marte to Triple-A Louisville in corresponding transactions.
