Jack Cust, 32, hit 84 homers for the A's from 2007 to 2009. He entered this season, his 10th in the majors, with the Mariners, but inconsistency (.213 batting average) and lack of production (just three home runs in 270 plate appearances) led to his release at the end of July.
According to a tweet from Todd Zolecki, the signing is pending a physical. Should he pass, Cust, a 245-pound left-handed hitter, will head to Lehigh Valley.
Note: Cust attended Immaculata High School in Flemington, NJ before being drafted by Arizona in the first round of the 1997 draft. Flemington is just 50 miles from Philadelphia.
