Redding lasted 2 2/3 innings and gave up seven runs on seven hits. He ends the season at 10-11 with a 4.95 ERA.
The veteran's outing was rough from the start. On the first pitch of the game, Redding gave up a home run to Hanley Ramirez.
After Cameron Maybin doubled, Jorge Cantu was hit by a pitch. The Marlins actually thought Redding hit Cantu on purpose and umpires issued warning to both clubs. Acta said it was clear that Redding was not trying to hit Cantu.
"The Marlins thought Tim did it on purpose. Tim was just trying to come in because they had a man on second and nobody out. You don't want to pitch the ball away. He could have moved the guy over to third," Acta said. "The ball just got away and hit him. That's my point of view."
Redding didn't record an out until Josh Willingham hit into a double play, which allowed Maybin to score.
Redding managed to make it through the second inning unscathed, but the Marlins batted around and scored five runs in the third inning to chase him. Jeremy Hermida highlighted the scoring with a two-run single.
"He couldn't make good pitches. He was up in the zone," Acta said of Redding. "There were situations where he could have gotten out of the jam, but he allowed a bunch of runs in the third inning. He gave up two very hard-hit balls on 0-2 counts. He couldn't make good pitches when he had to."
Redding believed he would have a good game. While in the bullpen warming up, Redding had a great fastball and the curveball was breaking, but the game was a different story.
"I never had a chance to use all of my pitches," Redding said. "The Marlins are a fastball-hitting team. We have known this all year. No matter how big your ego is, sometimes you have to take your medicine and try to use your other pitches. I just felt too strong and too good with my fastball warming up."
It was a tale of two seasons for Redding. During the first half of the season, Acta looked at Redding as an All-Star candidate. He was 7-3 with a 3.85 ERA. After the All-Star break, Redding slumped badly and had an ERA over 6.00. But the right-hander made no excuses for his poor showing during the second half, pointing to his inability to execute his pitches and his not getting ahead in the count early enough.
Asked what he thought of his season, Redding said, "First half, real good. The type of half you would hope to have for a full season. Second half, the numbers speak for themselves. As a whole, I can take some good and take some bad. It's sad. I happened to look back in the last 2 1/2 months and know that I let things slip away. It makes me hungry [to get ready] for next year."
Redding is arbitration-eligible, and the Nationals will decide whether or not he comes back next season. Redding made it clear where he wants to be in 2009.
"I made it public with the people that needed to know that this is where I'm comfortable," Redding said. "This team is going in the right direction. I think we are going to be good next year, and we have the pieces that we need."
Redding's counterpart, Marlins right-hander Josh Johnson, was solid. He lasted six innings and gave up two runs on six hits. The Nationals scored twice in the third inning off Johnson. Emilio Bonifacio highlighted the scoring with an RBI triple.
Pete Orr and Wil Nieves each singled in a run off Florida reliever Ryan Tucker in the eighth.
The Nationals are now 59-99 for the season.
