The battle between Bernhard Langer and Mark Wiebe for the Senior British Open golf Championship will go into a fifth day after bad light brought an end to play following the second playoff hole at Royal Birkdale.
The pair were locked at nine-under par after 72 holes after German Langer blew a two-shot lead on the final hole with a double bogey to send the championship into a playoff.
Play had earlier been held up twice due to rain and the threat of thunder and lightning.
the New Zealander Greg Turner finished 20th, 13 shots from the leaders.
