Red Sox General Manager Ben Cherington said yesterday that newly-signed OF Rusney Castillo will— "barring something unforeseen''—see action with the major league club in September. Said Cherington, "We'll try to take advantage of whatever minor league games we have left. We haven't looked past this current series with Portland. I think what we want to do is sort of maximize the number of at-bats he gets and sort of balancing that with the transition back. There may even be off-days built into this progression." Castillo played in last night's Sea Dogs playoff game and went 1 for 3 with a hit, a stolen base and a runs scored.
