MLB.com's Peter Gammons reports that the Orioles have placed Darren O'Day on revocable waivers.
Gammons says the waivers will expire on Friday. O'Day almost surely will be claimed, as he's making just $4.5 million this season and is in the midst of the best season of his career. The Orioles are still in the American League Wild Card race and seem unlikely to deal the reliever.
MLB.com's Peter Gammons reports that the Brewers have placed Francisco Rodriguez on revocable waivers.
Gammons notes that the waivers will expire on Friday, so he must have been placed on them a couple days ago. There will surely be interest in K-Rod, who has a very reasonable contract and is having a great season. Whether the Brewers will be able to work out a deal remains to be seen.
Manny Banuelos (elbow) tossed two scoreless innings in his first rehab start with Triple-A Gwinnett on Thursday.
Banuelos walked two and didn't recorded any strikeouts, but he yielded just one hit. The left-hander will make at least a couple more rehab start before hopefully rejoining the Braves' rotation at some point in September.
Rockies optioned RHP Tommy Kahnle to Triple-A Albuquerque.
It's been quite a fall for Kahnle, who was closing for the Rockies a few weeks ago and now finds himself in the minors. He can't be surprised at the demotion after allowing 10 earned runs and walking nine over his last 4 2/3 innings.
Rockies released RHP Rafael Betancourt.
Betancourt was designated for assignment earlier this week and is now officially a free agent. With a 6.18 ERA on the season, the 40-year-old's days in the majors could be over.
