Not sure about this signing, but he does strike people out (if he doesn't walk them or give up a home run). Perhaps a change of scenery is just what he needs to become a quality relief pitcher.
"Aquino was a league average reliever not too long ago. Last season played out much like 2007 though, with most of the season spent in Triple-A, and a handful of innings in the majors. Aquino didn't show his groundball inducing skills last season, but encouragingly did get a good percentage of swinging strikes in Norfolk, 14.3%. One of Mark Shapiro's weaknesses has been bullpen building, not alliteration, so if nothing else, this is a nice depth signing for 'Bus. Best case he turns in 20-25 innings of league average work in response to an injury."
