2019 USBC Open Championship (D & S)

USBC Open Championships

The 2019 USBC Open Championship pattern is a demanding 42-foot track featuring 28.4mL of heavy oil with a steep 2.25:1 forward-to-reverse ratio, creating a sharply defined oil wall that heavily favors controlled angular attack angles and precise breakpoint manipulation. The asymmetrical conditioning, 20.43mL forward versus 7.97mL reverse, forces bowlers to commit to specific lines early, as the extreme oil carrydown will punish any attempt to play the boards or adjust laterally mid-block. At this length and volume, stroking speed bowlers and pearl-dominant equipment gain a distinct advantage over slower, reactive surface styles, while the 631 boards of coverage demand excellent rev-rate consistency to navigate the steep transition from the heavy frontend to the dried-out backend.
