D'Backs designate Zagurski for assignment

The Diamondbacks have designated pitcher Mike Zagurski for assignment. Zagurski was the last lefty in Arizona's bullpen after the Red Sox acquired Craig Breslow a few weeks ago.

Zagurski has a 6.18 ERA in 27.2 innings of work this season. At the Triple-A level, he owns a career 2.82 ERA with 11.0 K/9.
