Lyon has been placed on the 15 day DL as of wednesday PM.
HOUSTON (AP) -- The Arizona Diamondbacks placed closer Brandon Lyon on the 15-day disabled list Wednesday night because of mild tendinitis in his right elbow.
Lyon had been held out of Arizona's last five games after pitching in three straight last week. He was feeling some discomfort in his right arm following that stretch and Diamondbacks manager Bob Melvin chose to be cautious with Lyon, who missed all of the 2004 season after having surgery on the ulnar nerve in his elbow.
``This will give us time to make sure he's 100 percent,'' Melvin said, ``and that his mind is clear before we bring him back.''
The 25-year-old Lyon had recovered nicely from the surgery and is tied for the league lead with 13 saves. His role will be filled by reliever Brian Bruney, who got his third save of the season against Houston in a 7-6 win Wednesday night.
``Right now it's better for me and the team to take some time off and straighten things up a little bit,'' Lyon said.
The Diamondbacks promoted infielder Matt Kata from Triple-A Tucson to take Lyon's roster spot.
