The Cleveland Indians announced Yandy Diaz and Michael Martinez made the 25-man roster, filling two question marks to start the season.
Giovanny Urshela and Erik Gonzalez were optioned to Triple-A and the Tribe will have to make a move on the 40-man roster as a result.
Heading into the season, Diaz will likely see significant playing time at third base, until Jason Kipnis is healthy.
The right-hander hit .318 with nine homers and 58 RBI in 2016, spending the majority of the season at Triple-A Columbus.
In Spring Training, the 25-year-old is hitting .429 with 2 home runs and 13 RBI.
