The entry deadline for this season's USBC National Bowling Championship tournament has been extended to March 30. More than 15,000 teams already have signed up for the event, which will be held at the National Bowling Stadium in Reno, Nev., beginning Feb. 17 and ending June 30.

The reason for the extension is not because of a lack of entries, but to give more USBC members a chance to compete in the tournament, said Roseann Kuhn, USBC chief of tournaments and events, who added that entries have been coming in at a steady pace.

This is the fifth time the tournament has been held at the newly remodeled National Bowling Stadium.

If you miss the pocket or hit it light, make the 2-to-1 adjustment in the direction that the pocket was missed.A parallel adjustment is when you move your feet and your target the same number of boards, meaning if you move two boards with your feet, you should move your target two boards as well.
