yeah Rojas has quietly hit and defended well since he came back up, it's just that the team hasn't always been going good, and he hasn't played as much. So nobody notices.
Still think he's the CF in the long run. Hays has a .543 OPS against RHP since coming over (there was a Philly Voice article about this today though it's main critique was the Phillies should have made a bigger trade. Not sure I even agree with that. Rojas and Marsh were good enough from April to June; hopefully they will be good enough in October, with Hays still an upgrade over Merrifield against LHP and in the OF).
