MLB.com's Bill Ladson reports that the Nationals designated reliever Kip Wells for assignment to make room for Tyler Clippard. Wells, a 32-year-old righty, has an ERA of 6.49 in just over 26 innings, with 18 strikeouts and as many walks.
It's possible that Clippard will be the Nats' best reliever, as he's dominated Triple A so far this year. He backs up his sparkling 0.92 ERA with 42 strikeouts in 39 innings, and just 20 hits and 15 walks allowed.
