Inconsistency is Monty's major concern
Montgomerie fired his best score of the week in the final round of the Scandinavian Masters on Sunday, but a closing 66 was nowhere near good enough to retain his title.
Rounds of 70, 69, 74 and 66 left the Scot on five under par and in a tie for 25th place, nine shots behind eventual winner Graeme McDowell.
