Jamie Smith's latest Test fifty took England into a narrow first-innings lead in their series opener against Sri Lanka at Old Trafford on Thursday. England were 259-6 in reply to Sri Lanka's 236, a slender advantage of 23 runs, when a combination of bad light and rain forced an early close to the second day of the three-Test series. Smith, promoted up the order to No 6 in the absence of injured captain Ben Stokes, was 72 not out -- the 24-year-old wicketkeeper's third fifty in his four Tests.
