To clear space for one lefthanded reliever on the 40-man roster, the Phillies removed another.
Sergio Escalona was designated for assignment Saturday to make room for the signing of J.C. Romero.
Escalona, 26, had a 3.81 ERA at double-A Reading in 2010. He struck out 53 in 54 1/3 innings and allowed just 46 hits.
He reached the majors in 2009 and pitched in 14 games with a 4.61 ERA. But he had a disappointing 2010 spring training and could not reach triple-A Lehigh Valley in 2010.
Escalona was originally signed by the Phillies out of Venezuela in 2004.
The Phillies now have 10 days to either place Escalona on waivers, trade him, or release him.
