Poston has withdrawn from this week's RBC Canadian Open, Rob Bolton of PGATour.com reports.
Analysis:
Poston also withdrew from his U.S. Open Final Qualifier on Monday after winning the Memorial Tournament which moved him up to 39th in the OWGR. Poston will make it into the field at Shinnecock, so he can take a week off to celebrate his huge Signature Event win and focus all his upcoming attention to the U.S. Open. This win at Muirfield Village really came out of nowhere, as Poston had not finished better than T21 in any event in 2026. Ben Martin will take his spot in the field this week at the RBC Canadian Open.
