I'd be very careful not to give them any more opportunities to fight. Like leashed outside time and taking away all the tennis balls, for starters. And not giving her couch privileges right away. I'm sure they'll have a great time together eventually, but let her settle in first. Good luck, I'm jealous - I'd love to have another pup here with my guy, but DH couldn't take all the fun we'd have together, lol.
ETA: even tethering her indoors too, and keeping Sabo from initiating anything with her. Let her get comfortable and relax, to get used to everything.
