If a ball in play cannot be found or recovered, any
fielder may call Lost ball. The ball shall then become
dead. See Law 23.1 (Ball is dead). Law 18.12(a) (Batsman
returning to wicket he has left) shall apply as from
the instant of the call.
2. Ball to be replaced
The umpires shall replace the ball with one which has
had wear comparable with that which the previous ball
had received before it was lost or became irrecoverable.
See Law 5.5 (Ball lost or becoming unfit for play).
3. Runs scored
(a) The penalty for a No ball or a Wide, if applicable,
shall stand, together with any penalties under any of
Laws 2.6 (Player returning without permission), 18.5(b)
(Deliberate short runs) or 42 (Fair and unfair play)
that are applicable before the call of Lost ball.
(b) The batting side shall additionally be awarded either
(i) the runs completed by the batsmen, together with
the run in progress if they have crossed at the instant
of the call, or
(ii) 6 runs, whichever is the greater.
4. How scored
If there is a one run penalty for a No ball or for a
Wide, it shall be scored as a No ball extra or as a
Wide as appropriate. See Laws 24.13 (Runs resulting
from a No ball - how scored) and 25.6 (Runs resulting
from a Wide - how scored). If any other penalties have
been awarded to either side, they shall be scored as
penalty extras. See Law 42.17 (Penalty runs).
Runs to the batting side in 3(b) above shall be credited
to the striker if the ball has been struck by the bat,
but otherwise to the total of Byes, Leg byes, No balls
or Wides as the case may be.
