Bear in mind that he's been batting down the order at 7 or 8, so with the tail the majority of the time, and not always with Surrey in the best of positions - his average since that game (including the knock of 46 against Sussex) has been 38.3. Only Afzaal, Ramps and Mark Butcher averaged more last season.
Schofield batting for England (yes, England).
Since he only managed 22 wickets at the poor average of 61, its fair to say he's more of a batsman these days than a bowler. Given the woes experienced by the Surrey top order, Afzaal in particular, would it be out of the question to move Schoey up the order? The batting stocks at Surrey aren't exactly overflowing with talent knocking on the door, I can think of worse ideas.
He has proved he can score big runs with that 144 against Essex, and the way in which he forced his way back into the side shows he has got the right sort of attitude. He dragged the tail along to a single batting point against Sussex, and he seems well liked among the players.
Maybe its something to experiment with in the limited overs stuff initially, but I wouldn't be surprised or disappointed to see him move up the order in any form of cricket.
