It felt like everyone on Monday at The Northern Trust was in for a mistake, save for Jon Rahm, who was not going to allow for any margin of error.
Cam Smith, leading Rahm by one, made double bogey at the par-4 fifth. Tony Finau, one back, bogeyed the par-5 eighth. Erik van Rooyen, playing in the final group, made quadruple-bogey-7 at the par-3 11th to end his bid.
One slip – let alone a full faceplant – by others appeared to give Rahm the cushion he needed to win the first playoff event in this weather-delayed final round.
