In Avilan, the Phillies land a quality left-handed reliever who should help them down the stretch (and possibly in the postseason). He instantly becomes Philadelphia's top lefty reliever.

In Paulino, the White Sox get a versatile right-hander who is still 23 years old. Therefore, he has a chance to find his way to the big leagues at some point. He is not a top prospect, though.

Avilan was seeing save chances with the White Sox recently, so his fantasy stock may dip if used strictly as a situational left-hander with the Phils. Paulino is off the fantasy radar until further notice and is not much of a keeper prospect.
