According to the Cleveland Plain Dealer, the Diamondbacks are interested in acquiring Jake Westbrook. The 28 year-old righty is 5th in baseball with a 2.93 groundball/flyball ratio.
The leader, of course, is Brandon Webb at 3.15. Miguel Batista is also in the top 20. Perhaps Josh Byrnes plans on assembling a groundball-heavy pitching staff to match up with Orlando Hudson and the rest of his defensively sound infield.
If so, Byrnes could also target Cory Lidle now or in the offseason. Their reported interest in Dontrelle Willis fits into this agenda as well. I would guess that a deal for Willis or even Westbrook would require the inclusion of one of their top ten prospects. Westbrook was last seen in a trade rumor from January, when the Reds expressed interest.
