From the SF Gate Chronicle:
I just got off the phone with Dan Johnson's agent, who said that Tampa Bay claimed Johnson this morning. Johnson confirmed it, as well.
"It's been a long 10 days,'' Johnson said. "I've just got to get back into the swing of things. I can't complain, it's a big-league job. I'm still going.''
Apparently the A's couldn't swing a deal for Johnson, but the team had hoped to hang onto him rather than lose him to waivers. Johnson was out of options, though.
With Cliff Floyd out for a month or so, Johnson is likely to be DHing a lot, and he could do well hitting in that ballpark. He also has had a lot of success against some of the AL East clubs, so he could be a nice pickup for the Rays.
