For the goalie who had the most shutouts in 2010, what's his catching hand?
the most shutouts refer to MAX(SHO); catching hand refers to shootCatch; year = 2010;
SELECT T2.shootCatch FROM Goalies AS T1 INNER JOIN Master AS T2 ON T1.playerID = T2.playerID WHERE T1.year = 2010 GROUP BY T2.shootCatch ORDER BY SUM(T1.SHO) DESC LIMIT 1
