Rowell said: "We still need to button up the No 10 position, and Mike must show us the Wales performance wasn't a one-off. We need him to string together quality performances. Mike still has a distance to go in terms of England, but showed, after we left him out during the Five Nations, that he is capable of bouncing back."
Catt, the Bath playmaker, steps into England's key role, having sat out all bar 80 minutes of the Five Nations campaign, when a recalled and revitalised Paul Grayson took over.
Rowell has set his 30-man squad the "minimum requirement" of winning every match against Argentina's amateurs, a feat previous England parties in 1981 and 1990 could not manage. Rowell supports the theory of his captain, Phil de Glanville, that Test places are up for grabs. The Sale full-back Jim Mallinder, the Wasps centre Nick Greenstock, the Bath lock Martin Haag, and the Harlequins flanker Rory Jenkins earn immediate chances, while others - notably Mark Mapletoft, the prolific Gloucester points scorer, and the Saracens captain Tony Diprose - are in the wings.
