Gibson was traded from the Rangers to the Phillies along with Ian Kennedy for an undisclosed package Friday, Jon Morosi of MLB Network reports.
Gibson is in the midst of a career year, sitting with a 2.87 ERA, 1.18 WHIP and 94 strikeouts in 113 innings (19 starts). He was slated to start Saturday, so it's possible he slots right into the Phillies' rotation this weekend in Pittsburgh, perhaps Sunday in place of Spencer Howard.
