Aronimink has delivered chaos through two rounds, and the betting implications are massive. Alex Smalley and Maverick McNealy share the lead at -4, while Scottie Scheffler sits just two back despite following his opening 67 with a Friday 71. What jumps out to me is how dramatically the DataGolf model’s live probabilities have shifted from pre-tournament expectations - and where sportsbooks haven’t kept pace.
Our Wednesday preview breakdown highlighted the course-fit dynamics of Donald Ross’s Aronimink layout, emphasizing approach play and scrambling over driving distance. After 36 holes, those predictions are holding up remarkably well. The leaders are gaining strokes in multiple categories, but the weekend odds haven’t fully adjusted to reflect who’s actually playing well versus who carried inflated expectations into Thursday.
This Week’s Betting Landscape
The outright market remains Scottie Scheffler-centric at +340 on DraftKings despite sitting T9 at -2. That’s shorter than pre-tournament odds, which tells you everything about how books view his weekend potential. The DataGolf model agrees he’s the favorite but assigns him roughly 13% win equity based on his +653 model odds - making +340 roughly fair value, not a screaming play.
What’s more interesting is the value gap opening up behind Scheffler. Maverick McNealy sits +1250 at co-leader, and Cameron Young at +970 sits T9 at -2, just two shots back. Both represent potential value based on their position and current form.
The longshot board is where I’m finding the most compelling discrepancies, similar to how course history and current form often create exploitable edges. Chris Gotterup at +1400 on FanDuel sits T3 at -3, just three shots off the lead. Min Woo Lee at +1475 is also T3 at -3. These aren’t “picks,” but the model sees them as mathematically underpriced relative to their position and skill.
Value Plays: Where the Model Disagrees
The DataGolf model’s live probabilities reveal significant pricing inefficiencies heading into the weekend. I’m not telling you what to bet, but these are the spots where the math diverges from the market.
Maverick McNealy (+1250 DraftKings): McNealy co-leads at -4 after rounds of 69-67, showing consistent ball-striking and scoring ability. His baseline skill level doesn’t match Scheffler’s, but he’s executing better this week. The model had him as a longshot pre-tournament (not even top 20), yet here he sits sharing the lead. At +1250, he offers value for a co-leader position heading into moving day.
Cameron Young (+970 DraftKings): Young sits T9 at -2 after rounds of 71-67, just two shots back. His second-round 67 shows he’s gaining momentum at the right time. The DataGolf model gave him strong pre-tournament win equity (fourth-best in the field based on skill), and his current position validates that projection. I like this number better than Scheffler’s at +340.
Chris Gotterup (+1400 FanDuel): Gotterup sits T3 at -3 after rounds of 72-65, demonstrating the ability to post a low number on this tough Donald Ross layout. His Friday 65 was one of the lowest rounds of the day. At +1400, you’re getting solid odds on a player three shots off the lead with proven scoring ability this week.
In this breakdown, Odds Shark’s team discusses longshot strategy for the PGA Championship, emphasizing course-fit metrics over reputation. Their analysis aligns with the DataGolf model’s emphasis on current form over historical pedigree at major championships.
Ludvig Åberg (+1175 DraftKings): Åberg sits T9 at -2 after solid rounds of 71-67. His skill-based projection (elite baseline strokes gained profile) suggests he should be closer to the leaders. If he posts a low number Saturday, the odds will crash. At +1175, there’s potential value if he continues his Friday momentum.
Jon Rahm (+1275 DraftKings): Rahm sits T16 at -1, four shots back, but his baseline skill level (elite strokes gained profile, fifth-best in the field) keeps him dangerous. His weekend surge potential makes him a live longshot if the leaders falter. The +1275 odds provide reasonable value for a former major champion with proven closing ability.
Strokes Gained Breakdown
After 36 holes, the leaderboard reveals which skill categories are separating contenders from pretenders. Approach play and putting are dominating, exactly as our preview article predicted for Aronimink’s Donald Ross layout.
Approach Play (SG:APP): The leaders are all executing well with their irons on Aronimink’s demanding greens. The small, undulating putting surfaces (average 5,500 square feet) reward precision iron play. Missing greens here leads to scrambling torture.
What jumps out to me is that several pre-tournament favorites struggled with approach. Collin Morikawa never found his iron game on a course that should have suited him. The players advancing to the weekend are those who’ve consistently hit quality approach shots.
Putting (SG:PUTT): The putter has been the great equalizer. Alex Smalley co-leads the tournament despite modest driving numbers because his putting has been exceptional. That level of putting performance is difficult to sustain over four rounds, but it’s kept him in the hunt through 36 holes.
Cameron Young’s improved putting through two rounds is remarkable given his career baseline. If that continues Saturday and Sunday, combined with his elite driving, he’ll be extremely difficult to beat.
Off-the-Tee (SG:OTT): Accuracy matters more than distance at Aronimink. The fairways aren’t especially tight, but missing them leaves you hacking from thick rough with limited green access. Chris Gotterup and Cameron Young are both gaining significant strokes off the tee while maintaining approach precision.
Scottie Scheffler’s driving numbers through two rounds are below his typical baseline. If he tightens up the driver Saturday, understanding which strokes gained categories actually predict winners becomes crucial for evaluating his chase.

The weekend pairings offer some exploitable matchup spots based on course fit and current form. I’m using DataGolf’s live matchup probabilities alongside the skill profiles to identify edges.
Shane Lowry vs Brian Campbell: This is a blowout on paper. Lowry didn’t make major noise Thursday or Friday but should have significant skill advantages over Campbell, a PGA professional making his major championship debut. I’m not seeing value in laying heavy juice, but if you’re building parlays, Lowry is about as safe as it gets in a Saturday pairing.
Chris Kirk vs Dan Brown: This is one of the more interesting weekend matchups from a value perspective. Kirk sits T59 at even par after rounds of 73-73, while Brown is similarly positioned. Kirk’s baseline strokes gained profile gives him the skill edge, but his recent form has been shaky. The matchup pricing suggests sharp money recognizes Kirk’s underlying ability.
Justin Rose vs Kristoffer Reitan: Rose and Reitan are both hovering near the weekend bubble. Rose’s approach play baseline should give him the edge on Aronimink’s demanding greens, but Reitan has been solid in limited PGA Tour starts. Rose offers value if you believe in his major championship experience edge.
R1/R2 Recap and Weekend Storylines
The cut line fell at +4, eliminating several pre-tournament favorites. Players who shot even par or better comfortably advanced to the weekend, while those struggling to break par faced an uphill battle.
Alex Smalley and Maverick McNealy share the lead at -4, but neither was on anyone’s outright radar pre-tournament. Smalley wasn’t even in the DataGolf model’s top 20 win probabilities. McNealy was projected at roughly 1% win equity. That’s major championship chaos in action - Donald Ross layouts reward current form and ball-striking precision over pedigree.
The most compelling weekend storyline is Scottie Scheffler’s chase from T9. He opened with 67 on Thursday, then stumbled to 71 on Friday. His baseline skill level dwarfs everyone ahead of him. The DataGolf model gives him strong win equity despite sitting two back - higher than anyone else by a significant margin.
Hideki Matsuyama sits T3 at -3 and has been quietly brilliant through two rounds. His +1400 DraftKings odds provide value, and Matsuyama’s major championship experience (2021 Masters winner) makes him dangerous if he gets hot Saturday.
Chris Gotterup is the biggest surprise at T3. He opened with 72 but fired 65 on Friday, showing the scoring potential on this Donald Ross layout. Min Woo Lee sits T3 alongside him with impressive scrambling through 36 holes. His short-game excellence could be the difference maker if his ball-striking stays sharp.
Cameron Young sits T9 at -2 with some of the cleanest ball-striking numbers in the field through two rounds. If the putter stays hot, he’s going to be in the final pairing Sunday. His +970 DraftKings odds look underpriced given his skill level and current position.
Key Stats to Watch
Scrambling Percentage: Aronimink’s greens are brutally difficult to hit in regulation, and the rough is penal enough that up-and-down opportunities are scarce. Max Greyserman leads the field in scrambling through two rounds, which explains how he’s sitting T3 at -3. Min Woo Lee is similarly relying on short-game magic.
The hardest holes this week are all demanding scrambling skills when players miss greens. If you’re betting players who typically excel around greens, their scrambling stats this week matter more than their baseline numbers.
Greens in Regulation: Stephan Jaeger leads the field at 83.3% GIR, which explains why he sits T3 at -3. Patrick Cantlay, Harris English, and Ludvig Åberg are all hitting greens at elite rates. Aronimink’s Donald Ross design rewards precision iron play, and players who avoid scrambling situations are consistently scoring better.
SportsGrid’s updated predictive market odds provide context for how the live betting lines have shifted after R1/R2. Their analysis of where sportsbooks are adjusting versus where the DataGolf model sees value aligns with several of the discrepancies I’ve highlighted above.
Par-4 Scoring Average: The par-4s at Aronimink are the real test this week. Hole 16 (par-4, 227 yards) has played to a 4.763 average through two rounds, making it the toughest hole on the course. Hole 10 (par-4, 4.417 average) and Hole 18 (par-4, 4.295 average) are similarly brutal. Players who can consistently make par on these holes - avoiding bogeys and doubles - are the ones climbing the leaderboard.
Scottie Scheffler’s weekend chances hinge on cleaning up these difficult par-4s. His elite approach play baseline should give him scoring opportunities the leaders can’t match, but he’ll need to avoid the costly mistakes that plagued his Friday round.
