ESPN.com's Buster Olney reported (via Twitter) earlier in the week that the Phils would like to add an arm "higher in caliber" than Jeremy Guthrie, and Haren certainly qualifies. However, Philadelphia is far from the only team looking into acquiring the 29-year-old. We heard yesterday that the Nationals expressed interest in Haren, and that the Cardinals also covet the right-hander. Those two clubs, along with the Yankees, Tigers, and Twins, have scouted the Diamondbacks' ace recently.
The Phillies' fourth and fifth starters behind Roy Halladay, Cole Hamels, and Jamie Moyer have had their struggles this year. Kyle Kendrick has posted a 4.88 ERA in 15 starts, and even after three straight quality starts, Joe Blanton's ERA still sits at 6.19. Given the question marks in their rotation, the Phillies have made starting pitching depth a priority as the trade deadline approaches.
