7:00pm: Nick Piecoro of the Arizona Republic reports that the D'Backs are looking for pitching in exchange for Haren. Derrick Hall tells Piecoro that the team would need an "A-plus" offer to deal their ace.
"Ideally what we would ask for is major-league ready pitching, be it starters and/or bullpen, and prospects,” Hall said. “The volume doesn’t matter. It doesn’t need to be four or five or six guys. It’s really about the quality.”

4:05pm: The Yankees, Phillies, Cardinals and Twins are also pursuing Haren, according to Ken Rosenthal and Jon Paul Morosi of FOX Sports. The D’Backs are not close to a deal with anyone.
We should note that Bob Nightengale of USA Today reported last night that the Twins are 'barely monitoring' Haren, since they're on his no-trade list (Twitter link).
2:08pm: The Diamondbacks are exchanging names with teams interested in Dan Haren and the Detroit Tigers are among the clubs with 'serious' interest in the right-hander, according to ESPN.com's Buster Olney (all Twitter links). The Tigers' interest is not surprising, since they need rotation help, have three high-priced pitchers coming off the books next season and scouted Haren (along with the Phillies) last night.
Haren can block deals to a dozen teams, but would consider allowing a trade, depending on the situation. The Cardinals and Phillies are among the teams interested in Haren. He won't come cheap, but as one MLB official explained to ESPN.com's Jayson Stark, Haren's price may be dropping.
"[The D'Backs are] starting to get more reasonable," the official said. "Before, they were asking for two starting pitchers off your major league roster. Now they're talking prospects, so I think they've gotten realistic. I definitely think he's moving now."
Haren makes $12.75MM in 2011 and 2012, and there's a $3.5MM buyout for a $15.5MM option in 2013.
