Reliever Logan Ondrusek, infielders Didi Gregorius and Henry Rodriguez, and outfielder Denis Phipps will join the Reds on Saturday. Catcher Devin Mesoraco, who was optioned to Louisville on Aug. 23, will be recalled on Sunday. The Reds had to wait 10 days to recall Mesoraco. Right-handed pitchers Todd Redmond and Pedro Villarreal will join the Reds on Tuesday after the conclusion of Louisville's season.
Ondrusek, Redmond and Mesoraco spent time with the Reds already this season. Ondrusek was sent to Louisville when the Reds needed a catcher while Mesoraco served a two-game suspension. The reliever is 3-2 with a 3.50 ERA in 53 appearances this season.
Redmond made a spot start in the second game of the Reds' doubleheader against the Cubs on Aug. 18. He went 3 1/3 innings and allowed four runs on seven hits. He is the only pitcher outside of the current rotation to make a start for the Reds this season.
Mesoraco batted .210 with a .352 slugging percentage in 162 at-bats with the Reds.
Gregorius (who will wear No. 68), Phipps (No. 23), Rodriguez (No. 67) and Villarreal (No. 65) will be joining a Major League roster for the first time.
Gregorius, known as a slick-fielding shortstop, batted .243 with six homers and 23 RBIs at Louisville. Phipps batted .221 in 357 at-bats with Louisville, hitting 15 homers and racking up 45 RBIs. Rodriguez, a second baseman, hit .244 in 51 games for Louisville. In 20 starts, Villarreal posted a 4.61 ERA.
The Reds also reinstated infielder Kristopher Negron from the Louisville disabled list, recalled him from Louisville and placed him on the Reds' 15-day disabled list. Negron hasn't played since July 5 with a right knee injury.
Negron must stay on the disabled list until Sept. 15. The move means the Reds could use Negron in the last two weeks of the season.
