Time is running out for Colin Montgomerie to secure his US Masters place.

The Scot has dropped from 54th to 59th in the world rankings as a result of missing the halfway cut in the Johnnie Walker Classic in India - but he needs to be in the top 50 to qualify for Augusta.

The Scot has two more events - in Korea next week and then the CA World Championship in Florida - to make it back into the top 50 in time for the first Major of the season.

Meanwhile, Ernie Els is back up to third in the rankings after his Honda Classic victory in America at the weekend.
