Nelson
A score of 111, either for a team or for an individual batsman. Superstition holds that this score is unlucky and more likely to lead to a dismissal, due to its resemblance to the three stumps of the wicket (as if the bails had been removed). Tradition holds that the bad luck may be averted if spectators stand on one leg. Scores of 222 and 333 are known as double Nelson and triple Nelson respectively; these are sometimes also considered unlucky. Nervous nineties
The period of a batsmans innings when their score is between 90 and 99. Many players bat nervously in this period because they are worried about getting out before they reach a century. The fielding captain often sets an attacking field to increase the psychological pressure. Some players are particularly prone to getting out in the nervous nineties. Nets
a pitch surrounded on three sides by netting, used by for practice by batsman and bowler. Net run rate (NRR) 
In a match, the average run rate scored by a team minus the average run rate scored against them. In a series, a teams NRR is (total runs scored) / (total overs received) – (total runs conceded) / (total overs bowled). New ball
In professional cricket, a new ball is used at the beginning of each innings. In timed matches, the fielding captain has the option of taking another new ball after 80 overs have passed.

Hip Clip
a trademark shot of Brian Lara involving a flick of the wrist to whip a ball, at hip height, at right angles past the fielder at square leg. Hit the ball twice
A batsman is out hit the ball twice if having struck the ball once with their person or bat, they strike the ball a second time with their person or bat (but not a hand not holding the bat). A batsman is not out if the second strike was for the sole purpose of guarding their wicket. A batsman may not strike the ball a second time to prevent it from being caught (out obstructing the field). Hit wicket
a batsman getting out by dislodging the bails of the wicket behind them either with their bat or body as they try to play the ball or set off for a run. Hoick
an unrefined shot played to the leg side usually across the line of the ball. Hold up an end
A batsman who is intentionally restricting their scoring and concentrating on defence while their batting partner scores runs at the other end; or, a bowler who is bowling defensively to restrict runs at their end while their bowling partner tries to take wickets at the other end.
