Young, who underwent shoulder surgery last season, earned his first win on Tuesday against the Rays -- his first since his New York debut on April 5, 2011. The start marked his second since rejoining the Mets earlier this month -- he made his post-surgery debut on June 5 against the Nationals, but was placed on the paternity leave list the next day.
"I think he showed the other day that his endurance is good," Mets manager Terry Collins said. "He actually pitched better at the end of the game than he did at the beginning of the game the other night. His velocity went up as the game went along so I think that he'll be ready for tomorrow."
In his start against the Rays, Young allowed nine hits, but limited Tampa Bay to just two runs over 5 2/3 innings. He tossed 106 pitches.
After taking the first two games of the series, the Reds will have ace Johnny Cueto on the mound as they look to complete the sweep and notch their sixth straight win. In his last start, Cueto turned in a complete game, one-run effort against the Indians to improve to 7-3.
"Our pitching has been great for us all year, from the starting rotation to the bullpen," Reds right fielder Jay Bruce said. "We've started hitting a little better lately and I think we're going to continue to do that. But pitching -- we go as the pitching goes. It's been great. Those guys have done a great job."
Mets: Seven-game hit streaks for pair
Both David Wright and Ike Davis extended their hitting streaks to seven games Saturday night.
Wright hit his league-leading 10th first-inning double off Reds starter Homer Bailey, driving in David Murphy for the Mets' only run in a 4-1 loss.
Davis, who had been mired in a career-worst slump, singled in the sixth. He is hitting .500 (10-for-20) during the span and has raised his season average to .193.
Reds: Valdez adjusting to center field
Wilson Valdez made his first starts in center field on Friday and Saturday against the Mets.
Including his two starts this weekend, Valdez has made just four career appearances in center field, but was called upon with regulars Drew Stubbs and Chris Heisey both injured.
"For me, it's all the same," Valdez said. "You have to go out there with the mindset of doing whatever you have to do to help the team win."
In addition to sound fielding, Valdez has given the Reds an extra kick from the No. 2 spot. He went 3-for-9 with three RBIs and one run scored in the first two games of the series.
After scoring 29 runs in their sweep over the Rays this week, the Mets have mustered just four in the first two games against the Reds.
Bruce hit his second home run in as many games Saturday, belting a three-run home run in the top of the first inning off Mets starter Jon Niese. Bruce hit an inside-the-park homer on Friday after Jason Bay crashed into the left-field wall attempting to make the catch.
