The Reds recalled pitcher Jumbo Diaz from Triple-A on Friday, the team announced. Diaz produced a 6.65 ERA over 23 innings of work earlier this season. To make room for Diaz, the team optioned pitcher Carlos Contreras to Triple-A. Contreras has a 6.08 ERA over 13 1/3 innings of work this season.
The Reds have promoted pitcher Nate Adcock from Triple-A Louisville and optioned pitcher Jumbo Diaz to the same club. Adcock owns a 2.96 ERA and 20:7 K:BB ratio in 24 1/3 innings with Lousville. His addition to the active roster will mean that a 40-man roster spot will be cleared prior to gametime. Diaz was 2-1 with a 6.65 ERA and 25:5 K:BB ratio in 23 innings. He had allowed a pair of earned runs in two of his last three appearances.
Reds reliever Jumbo Diaz escaped an eighth inning jam and earned his second win of the season on Thursday, over San Francisco. Diaz entered the tie game with the go-ahead runner on base. He recorded two outs on four pitches, three strikes, to end the inning. Diaz moved to 2-0 when the Reds scored the go-ahead run. His ERA now stands at 6.75.
Reds reliever Jumbo Diaz is making his case for the eighth-inning setup role ahead of closer Aroldis Chapman, pitching in the eighth inning in each of his team's first three games and delivering 2 1/3 innings with four strikeouts. "He is [making a good case]," Price said before Friday's game, per MLB.com, adding, "He had a really good slide. I felt like the way you can tell if a slider is a good pitch is by the reaction of the hitter. ... You see (Andrew) McCutchen and some of those guys in there, that were in front of a slider and that comes down to pitch recognition and not being able to identify the pitch until you've made a swing commitment to the ball. I was very impressed with the way he threw. He seems to be built for these late-game situations. This year more than last, he'll have some of those opportunities." Diaz made 37 appearances for the Reds in 2014, posting a 3.38 ERA and 37:14 K:BB ratio in 34 2/3 innings.
After a rough outing for Reds pitcher Kevin Gregg on Monday, manager Bryan Price was asked if Gregg would be the guy in the eighth inning going forward. "He may be. He may not be," Price replied. "It just depends on who I have healthy and who is down there. He's a guy who is experienced as a closer, a setup man and a starter. He's a guy who has been a lot tighter situations than that over the course of his career. As I've told you, the bullpen will be ever evolving. These guys will cut out their roles based on how they perform," per mlblogs.com. Price acknowldeged that some adjustments will have to be made in the bullpen. "Once the eighth inning becomes a situational inning, it becomes a challenge," Price said. "We went into that game anticipating him pitching the eighth inning. It didn't go as well as we had anticipated. The eighth inning isn't really a matchup inning. We really had hoped that it would be a clean inning and it wasn't, so I had to make some adjustments there." Price added that pitchers Jumbo Diaz and Tony Cingrani could be in the late-inning mix.
