Earlier today, USBC released oil pattern 1 and oil pattern 2 for the event.

Oil pattern 1 measured 40 feet with a 1.84 to 1 ratio and 31 mL of oil. oil pattern 2 was set at 47 feet with a 1.63 to 1 ratio and 29.22 mL of volume. Now, the third oil pattern for qualifying has been confirmed.

Oil pattern 3 will be short and flat. The pattern measures 35 feet in length and features a 1.36 to 1 ratio, with a total oil volume of 29.41 mL.

The U.S. Open is the second major of the 2026 PBA Tour season. From Tuesday through Thursday, players bowl eight games on the first three oil patterns before the first cut is made.

After 24 games, the field will be reduced to 36 players. Those remaining competitors will bowl another eight-game block on Friday. The field then will drop to 24 players for round-robin match play.

Total pinfall across 56 games will determine the five players who advance to the stepladder finals.

The finals will air Sunday on The CW.
