Will celebrate his 33rd birthday as The Open finishes on Sunday. He came into the field in the week before the Championship by claiming the third and final place on offer at the abrdn Scottish Open.
Senior was in a tie for 10th spot, but that was good enough as seven players ahead of him were already exempt. He would have lost out to Wade Ormsby by virtue of their respective world rankings if the Australian had birdied the last hole, but that did not happen.
For his three previous appearances Senior survived the 36-hole Final Qualifying event, producing two rounds of 67 at St Annes Old Links two years ago to be joint first alongside Garrick Porteous.
Victory in the 2011 Lytham Trophy helped earn him selection for the Walker Cup later the same season and at Royal Aberdeen he partnered Andy Sullivan to two wins, while losing his first singles to Jordan Spieth and then making a crucial 30-foot putt on the last to halve with Nathan Smith as Great Britain and Ireland won 14-12.
A winner on the European Challenge Tour both in 2015 and 2019, he went into the Scottish Open ranked 353rd in the world.
