The Phillies acquired minor league second baseman Albert Cartwright from the Houston Astros in exchange for left-hander Sergio Escalona, who was designated for assignment over the weekend.
Cartwright, 23, split the 2010 season between Single A Lancaster and Double A Corpus Christi. He hit a combined .294 with 30 doubles, 14 triples, 10 home runs, 55 RBI and 31 stolen bases in 127 games.
A 36th-round draft choice in 2007, Cartwright has hit .272 in his minor league career with 20 home runs, 112 RBI and 71 stolen bases in 284 games.
Escalona, 26, spent last season with Double A Reading, where he went 4-8 with a 3.81 ERA in 50 games. He had 53 strikeouts in 54.1 innings. He appeared in 14 games with the Phillies in 2009.
The Phillies had 10 days to trade, release Escalona or put him on waivers.
