PITTSBURGH (AP) — Oakmont’s already massive greens will be even more daunting when the men’s U.S. Open returns next summer for a record 10th time. The club situated in the northern Pittsburgh suburbs has restored more than 24,000 square feet of green surface over the last two years as part of a renovation guided by golf course architect Gil Hanse. The renovations will allow the USGA to experiment with new pin placements when the men’s championship returns to Oakmont for the first time since 2016.
