CINCINNATI -- With the Reds' bullpen weary after working a combined 9 1/3 innings over the past two games, Cincinnati recalled right-hander Carlos Contreras from Double-A Pensacola on Saturday and designated outfielder Roger Bernadina for assignment.
Contreras made his Major League debut in Saturday's 11-1 Reds win over the Blue Jays, pitching a 1-2-3 ninth inning and recording his first Major League strikeout, getting Colby Rasmus swinging to end the game.
The 23-year-old Contreras -- ranked as the Reds' No. 5 prospect on MLB.com -- appeared in nine games for the Blue Wahoos this season, including three starts. He went 2-1 with a 2.70 ERA and held opponents to a .195 batting average against. He features a fastball that can reach the upper-90s and a good changeup.
"I feel very excited; first game as a big leaguer, it was awesome," Contreras said. "I was a little nervous with it being my first game. It's tough if you don't get nervous. But it was very, very good. I was making quality pitches."
Manager Bryan Price was happy for Contreras, who is the second relief pitcher to make his big league debut in as many days for Cincinnati. Right-hander Jumbo Diaz made his first appearance in the seventh inning on Friday.
"Carlos was terrific," Price said. "I don't know what that experience is like as a player, unfortunately, to come into that situation. It was an 11-1 game. However, it was a Major League debut in front of a sold-out capacity crowd against a team that scored 14 the night before, in the middle of their lineup. I thought he handled it really well."
Bernadina, who hit .153 (9-for-59) with three doubles and five RBIs, was previously designated for assignment on May 3 when Skip Schumaker was activated from the disabled list, but returned to the club three days later when Jay Bruce went on the DL.
Reds relievers haven't been able to catch their collective breath as of late. In Friday's series opener against the Blue Jays, Cincinnati used six relievers who combined to give up nine runs, including three homers. It marked the first time Reds relievers have surrendered nine runs in a game since giving up nine over four innings on June 9, 2013 against the Cardinals.
Friday's collapse came on the heels of an extra-inning loss, 4-3, on Thursday against the Brewers in Milwaukee. The Reds also used six relievers in that game, five of whom pitched again on Friday (Sam LeCure, Logan Ondrusek, Manny Parra, Jonathan Broxton and Aroldis Chapman).
"A day off for the bullpen would be a huge step in the right direction," Price said. "When I talk about a quality start, I'm not talking about six innings. I'm talking about seven or eight innings. A couple of those back-to-back would do us a service for sure. We're going to need the starters to pitch, and if they don't pitch efficiently, they're going to still have to stay out there. That's just the way it is right now."
Saturday's starter for Cincinnati, Mike Leake, answered the call, giving the Reds eight strong innings to give the bullpen a breather before Contreras came into the game.
Jumbo stays positive after rude welcome in debut
CINCINNATI -- Jumbo Diaz waited 13 years to get to the big leagues, and though things didn't turn out the way he had envisioned in his Major League debut Friday against the Blue Jays, he is nonetheless excited about what the future holds.
The 6-foot-4, 278-pound right-hander entered the game in the seventh inning and promptly began hitting 98 mph on the radar gun. He allowed three runs on three hits in the frame, including two home runs (a solo homer by Brett Lawrie and a two-run shot by pinch-hitter Juan Francisco, both opposite-field homers).
"It's not the best outing I wanted last night, but I tried to go out there and throw strikes," Diaz said. "I faced one of the best teams in the league this year. They've got a lot of pop, and they got me yesterday. But today's a new day; I try to forget about yesterday and keep working and keep doing my best."
Manager Bryan Price saw positives in Diaz's debut performance despite the results.
"I certainly liked the velocity and the fact that he came in throwing strikes," Price said. "He didn't walk anybody in his inning. When guys throw hard you've got to get the barrel of the bat to the ball … He did have two guys hit the ball out of the park and both those guys caught the ball late, but got it to the barrel."
Price had a message for Diaz after his rough outing:
"I just patted him on the back and said, 'Hey, it'll get easier.'"
• According to the Elias Sports Bureau, after blowing an eight-run lead in Friday's 14-9 loss, the Reds became the sixth team in the last five seasons to lose a game after holding at least an eight-run advantage (teams that held at least an eight-run lead in that span are 1,158-6).
• Friday's game was the first since May 17, 1896, in which a Major League team won by five or more runs after its opponent scored eight or more in the first or second inning. That game was between the Brooklyn Bridegrooms and, of course, the Cincinnati Reds. Brooklyn led, 9-0, after the top of the first and Cincinnati came back to win, 16-10.
• Center fielder Billy Hamilton entered Saturday's game against the Blue Jays leading all National League rookies in multi-hit games (17), runs (35), hits (tied for first with 66), stolen bases (30) and outfield assists (tied for first with four).
