Dave Bush has opted out of his contract with the Phillies and will pursue an opportunity in Korea, Phillies Triple-A manager Ryne Sandberg confirmed to reporters, including CSNPhilly's Jim Salisbury (Twitter link). Dan Kurtz of MyKBO.net informs MLBTR that Bush will be replacing former big leaguer Aquilino Lopez on the roster of the SK Wyverns.
Bush, 32, signed a minor league deal with the Phillies this offseason and has spent the year pitching for Triple-A Lehigh Valley. The right-hander has pitched to a 3.16 ERA, 5.3 K/9 and 1.1 BB/9 in 62 2/3 innings of work for the IronPigs. He last saw Major League action as a member of the Rangers in 2011 when he posted a 5.79 ERA in 37 1/3 innings. Bush is represented by Turner Gary Sports.
