PITTSBURGH -- There has been a lot of talk about Diamondbacks pitcher Micah Owings and the Reds.

Yet as of Wednesday, Owings remained with Arizona. The fact is he has not even been placed on the waiver wire yet, two Major League sources told MLB.com. There have been erroneous reports circulating that the Nationals and general manager Jim Bowden put in a claim to block Owings on waivers and that he was pulled back.

Owings is believed to be one of two players to be named that will come to the Reds in the trade that sent outfielder Adam Dunn to the D-backs. The other player remains unknown. Minor League pitcher Dallas Buck has already been sent to the Reds and was assigned to Class A Sarasota.

If Owings were to be claimed by another team, Arizona would have to pull him back and he would not be able to join the Reds until after the season.

After the July 31 non-waivers Trade Deadline, all players on 40-man rosters involved in trades must clear waivers before being moved.

Only teams with a worse record than the Reds can make waiver claims to block players they would want. Currently there are four clubs in that position -- the Nationals, Padres, Giants and Rockies.

By rule, teams are not allowed to comment on the waiver process.

Owings, who was part of Arizona's playoff run in his rookie season in 2007, is currently pitching for Triple-A Tucson. His Wednesday start was scratched as a precaution because of a stiff right shoulder.

In 2007, Owings went 8-8 with a 4.30 ERA and made two starts in the National League Championship Series. It's been a step back this season, with the right-hander going 6-9 with a 5.93 ERA before his July 29 demotion to Tucson.

There are few pitchers handier with a bat than Owings. As a hitter, he's batting .313 (35-for-112) in his big league career.
