ALEX Marshall’s bid for a seventh world indoors singles crown remains on track after an opening round victory.

The bowls legend is among those taking part at the World Indoor Bowls Championship at the Potters Leisure Resort in Norfolk.

Yesterday (Thursday) saw him get his bid for another open singles title under way.

The Tranent bowler had to survive a scare against qualifier Mark McPeak, who took the first set 7-5.

However, Marshall, who last won the top prize in 2015, fought back.

He took the second set 11-4 to set up a tie-break and came through 2-0 to make it through to the last 16.

Marshall, who is seeded 15 at the championships, faces second seed Nick Brett on Thursday (January 20).

The Englishman overcame Loren Dion 2-0 in the first round.
