Four players emerged from a crowded leaderboard to share the first-round lead at the Senior PGA Championship on Thursday at The Concession Golf Club in Bradenton, Florida.
Steve Allan, Brian Gay, Miguel Angel Jimenez, and Bernhard Langer each carded six-under-par 66s on the 6,936-yard, par-72 layout to grab a one-shot lead in the $3 million tournament.
Allan fired rounds of 34-32, while Gay matched that score with an identical 34-32 performance. Jimenez took a different route to his 66, posting 31-35, and Langer joined the leading group with his own 34-32 round.
Three players sit one shot back at five-under 67. Ben Crane (32-35), Retief Goosen (34-33), and Thammanoon Sriroj (35-32) form the chase group heading into Friday's second round.
Several notable names struggled to find their rhythm on the opening day. Former major champions Stewart Cink, Ernie Els, and Vijay Singh all finished at three-under 69, putting them three shots behind the leaders but still in contention.
The field experienced varying degrees of success on the challenging Florida course. While the leaders capitalized on scoring opportunities, others found the conditions more demanding. Darren Clarke and Mike Weir, both major championship winners, opened with rounds of 74, leaving them eight shots off the pace.

Among those facing an uphill battle are Angel Cabrera, who struggled to an opening-round 81, and Rod Perry, who matched that score. Rocco Mediate withdrew from the tournament for undisclosed reasons.
The tournament features a strong international contingent, with players representing various countries making their mark on the leaderboard. The depth of talent in the senior ranks was evident throughout the opening round, with experienced campaigners showing they can still compete at the highest level.
Conditions at The Concession Golf Club appeared favorable for scoring, as evidenced by the low numbers posted by the leaders. The course's design and setup allowed skilled players to take advantage of birdie opportunities while still presenting challenges that separated the field.

With three rounds remaining, the tournament remains wide open. The one-shot margin at the top suggests that weekend positioning will be crucial for those hoping to capture the Senior PGA Championship title.
Friday's second round will be critical for players looking to make the cut and position themselves for a weekend charge. The leaders will aim to maintain their momentum while the chasing pack seeks to close the gap before the weekend rounds determine the champion.
