UPDATE (2:30 p.m.) - The Phillies have officially called up Asche from Lehigh Valley. To make room for Asche on the roster, Steve Susdorf was designated for assignment. Complicating the matter is Michael Young's no-trade clause.

The Phillies will promote third baseman Cody Asche from triple-A Lehigh Valley, a source confirmed, which means Michael Young is likely to be dealt before Tuesday's game against San Francisco.
Yahoo! Sports first reported Asche was being called up.
Young was always the most likely Phillies player to be traded at the deadline because teams are enamored of his veteran presence and decent bat. The 36-year-old infielder owns a full no-trade clause but he was willing to waive it to play for a contender.
The Phillies acquired Young from Texas for Josh Lindblom and Lisalverto Bonilla. Both pitchers have struggled in 2013. Young is owed about $2 million on his contract. The Phillies are not expected to receive a top prospect for him.
Asche, 23, is one of the organization's better position player prospects. He is hitting .295 at triple A with an .837 OPS. He has 15 home runs. He belted two in the IronPigs' 9-1 victory Monday. He has a 10-game hitting streak.
The fourth-round pick was converted to second base from third after college. He spent just one year at second before the Phillies shifted him back to third. Scouts believe he has the ability to play third base in the majors. The final two months of 2013 will serve as a tryout.
