Somerset spinner Jack Leach has hit a remarkable innings of 92 in his fifth Test match, defying his lowly career average and boosting England hopes of beating Ireland at Lord's.

Opening the batting on Wednesday evening as nightwatchman, with England 122 runs behind after the first innings, 28-year-old Leach shared a sizeable partnership with Surrey's Jason Roy

Taunton-born Leach, whose previous highest first-class score was 66, became the fifth ever nightwatchman to make a score in the 90s in Test cricket.

The left-hander was eventually dismissed just eight short of his century by Middlesex seamer Tim Murtagh.
