In need of a starting pitcher, York Revolution manager Mark Mason made a move Monday to acquire 29-year-old left-hander Logan Williamson in a trade with San Angelo, of the independent United League.

York announced the move Tuesday.

Mason had said Monday night, following York's 5-1 loss to Sugar Land, that Williamson, a former Chicago White Sox prospect, is expected to start Thursday at Camden.

Filling the gap: The Revs currently have a pair of holes in the starting rotation. Right-hander Matt Neil is recovering from a strain in his throwing arm after tossing a complete game on June 3 for the Revs and veteran Corey Thurman is with his family in Michigan tending to his ailing father.

As a result, three Revs starters went on three days rest in three of the last four games.

"The way we would go now it would be (Alain) Quijano, Logan (Williamson), Chris Cody and (Jorge) Martinez," Mason said Monday night on his plans for the starting rotation in York's four upcoming games following Tuesday's off day. "We would have nobody short at that point."

Williamson: Williamson began this season in the Mexican League, according to Mason. He was then released out of the Mexican League and went to the independent American Association, going 1-2 with a 6.62 ERA in three starts for Amarillo before being released.

Williamson soon signed with San Angelo, coming of the bullpen there three times before being acquired by York. The 6-foot lefty went 1-0 with a 3.60 ERA in three relief appearances for San Angelo, striking out four with no walks over five total innings.

His numbers this season are a far cry from the impressive stats he put up in his Atlantic League debut a year ago with Southern Maryland, when he went 5-3 with a 3.66 ERA in 31 games (12 starts), striking out 47 and walking 30 in 76.1 total innings.

Williamson's pro career began in 2004 after being drafted in the 27th round by the Chicago White Sox out of Pensacola (Fla.) State College. He reached the club's single-A level in 2005, and has since spent the next seven years playing in various independent leagues.

York is now at the Atlantic League maximum of 25 active players (Thurman is still inactive). Williamson's addition means three of York's starting pitchers are left-handed, joining Cody and Quijano.
