CINCINNATI -- The surging Cincinnati Reds will have all their key players for the first time this season after making a series of roster moves before Tuesday night's game against the Seattle Mariners.
The Reds activated infielder Matt McLain, right-hander Alexis Diaz and outfielder Austin Hays. Cincinnati goes into the three-game series with Seattle after wins in five of its past six, including its first series sweep of the season this past weekend against Pittsburgh.
McLain missed last year with a shoulder injury but got off to a strong start this season with home runs in three of his first four games. He went on the IL retroactive to April 5 with a slight left hamstring strain after going 1-for-12 in four April games.
McLain will play second base and is batting second in Tuesday's game.
Diaz, who was dealing with a left hamstring strain since the start of spring training, made a pair of rehab appearances in Triple A Louisville last week. He was projected to be the team's closer going into the season, but Emilio Pagán has converted all four of his save opportunities and has a 1.23 ERA in eight games.
Hays will make his Reds debut at designated hitter and bat fifth. He missed the first 16 games with a left calf strain that occurred on the final day of spring training.
Hays signed a one-year, $5 million deal with Cincinnati during the offseason after spending last season with Baltimore and Philadelphia.
Outfielder Jacob Hurtubise and infielder Noelvi Marte were optioned to Louisville to make way for McLain and Hays. Diaz takes the roster spot that opened after left-hander Sam Moll was placed on the 15-day injured list Monday due to left shoulder impingement.
