(Updates at tea)
LONDON, Aug 18 (Reuters) - Jonny Bairstow fell five runs
short of a maiden test century on Saturday before South Africa
safely negotiated the start of their second innings, reaching 33
without loss at tea on day three of the third and final test
against England at Lord's.
Alviro Petersen was 20 not out and captain Graeme Smith was
on 13 as the Proteas took a lead of 27 runs, with seven sessions
remaining in the match and series. England were earlier bowled
out for 315 in reply to South Africa's first innings 309.
Fast bowlers Morne Morkel (four for 80) and Dale Steyn (four
for 94) did most of the damage for the tourists.
England must win the match to square the series and prevent
South Africa leapfrogging them at the top of the world rankings.
Bairstow, in the team for the omitted Kevin Pietersen, was
bowled before lunch for 95 by Morkel. It was a courageous effort
by the 22-year-old after coming to the crease at 54 for four.
