CINCINNATI -- It was one of the few times a pitcher might be kind of glad he has arm tendinitis.
That's because Reds reliever David Weathers thought he was dealing with a far worse alternative.
Called from the bullpen to begin the eighth inning against the Cubs on Sunday, Weathers allowed Michael Barrett's leadoff single. Phil Nevin then slugged a 1-0 pitch for a two-run homer to left field. Matt Murton followed with a single to center field.
Weathers was seen stretching his arm, and pitching coach Tom Hume came to the mound with the trainer. After a few moments, Hume signaled for Chris Hammond from the bullpen, and Weathers walked off the field.
"I threw the first slider to Nevin, and my arm went to sleep," Weathers said after the Reds' 9-3 loss to the Cubs. "My hand was shaking real bad. I threw the next pitch -- home run. I tried to throw a pitch to Murton down and away, and I couldn't finish it. It felt terrible.
"I'll be honest with you. I've been playing since '88, and when I walked off the mound, I thought I tore it. I've never had that feeling before in my career."
Reds medical director Dr. Tim Kremchek examined Weathers and, after a few tests, diagnosed the 36-year-old setup man with shoulder tendinitis.
The team's closer until a couple of weeks ago, Weathers threw 24 pitches in the ninth inning during Saturday's loss. He warmed up to come in for the seventh, if needed, but starter Eric Milton escaped a jam and finished the inning.
"I'm not a young guy anymore," Weathers said. "When you throw 30 pitches as a relief pitcher, that's almost like a starter throwing 110. On top of that, it's a 13-to-14 hour turnaround [from Saturday]. All of those things factor in. But that's baseball. That's my job to go out there and pitch."
The pitcher will be reevaluated on Monday, but an MRI test was not expected to be necessary.
"Right now, we don't expect it to be a [disabled-list injury]," Reds manager Jerry Narron said.
"I would be very, very surprised," Weathers responded when asked about the DL. "They think, with a couple of days -- maybe three days -- of just rest, it's going to respond."
Weathers is 2-2 with a 4.38 ERA and nine saves in 28 appearances this season.
