The expected recall of Yunesky Maya and Ross Detwiler was widely reported over the weekend, and took place this afternoon, but there was also a surprise in the bunch: soon-to-be 28-year-old Joe Bisenius.

Bisenius, who was cut from spring training by the Philadelphia Phillies, was signed in May as he was gearing up for a stint as a reliever for the Sioux City Explorers of the independent American Association of Professional Baseball.

His next appearance will be his third as a major-leaguer, having appeared in two games in April 2007 for the Philadelphia Phillies. He was also recalled during the summer of 2008 for eight days with making an appearance.

Injuries to his back limited his ’09 campaign to just 20 games. He had previously suffered rotator-cuff injuries in ’08.

Bisenius has been reported to have (or be capable of) high-90s velocity, but it was not seen at Potomac during his stint in June. Overall, Bisenius has posted a 3.05ERA in 34 appearances with a 4-0 record and one save.
