Hole-in-one stats

There have been 4,290 holes-in-one in Mini Masters history. One hundred three thousand seven hundred eighty-eight (103,788) holes have been completed in officially recognized M.C. Mini Masters rounds. This means a hole-in-one is the result of approximately 4.13% of all MCMM tee shots.

Previous to 2011, the only hole score rarer than a one was a six. The performance by the 2011 tourney field (175 aces, 109 fives, 115 sixes) also dropped fives below aces. The numbers through 2026 stand as follows:
4,290 holes-in-one (4.13%)
48,823 twos (47.04%)
33,470 threes (32.25%)
11,090 fours (10.69%)
3,397 fives (3.27%)
2,717 sixes (2.62%)
There was also one score of seven by pro Gary Shiff in 2005, as the pro division recognized a seven-stroke maximum, so 0.0000096% of Mini Masters holes have resulted in a seven.

Mick Cullen recorded the first hole-in-one in tournament history by acing the first hole of the first round of the first M.C. Mini Masters at Congo River...with the first MCMM putt ever taken. He didn't get his second of the day until 53 holes later.

Mick also was the first to score 12 holes-in-one in one tournament, finishing the trick by acing Par-King Red's 17th and 18th to close his tournament championship in 2011 (and to best the 11 aces Jason Gola had posted minutes before). Mick repeated the 12-ace feat in 2012.

Joining Mick with twelve aces in one MCMM was 2012 rookie Mark Mason, who scored 12 holes-in-one thanks in large part to a record five at Action Territory, where only one person had ever scored four, where no other player in 2012 scored more than two, and where the other 37 players combined scored 12. Mark had back-to-back holes-in-one twice that day, including (coincidentally enough) Par-King Red's 17th and 18th holes, where Mick had garnered #11 and #12 the year before.

With his back-to-back 12-ace tournaments, Mick Cullen also set a two-year record for total aces with 24. In fact, in MCMM history, only six other players have ever had 24 holes-in-one in a three-year span: Ursula Cullen had 25 from 2008-2010, Jason Gola notched 25 from 2011-13, Matthew Cullen had 25 from 2014-16, 27 from 2017-19, and 28 from 2016-18 (twice leading the field in aces during those three tourneys), Mark Mason knocked in 24 in his first three MCMM appearances (2012-14), and Tom Schweiss recorded 24 from 2009-2011. Mick's three-year total from 2010-2012 was 31; he only had 32 aces in his first six Mini Masters appearances.

Derek Hartmann and Xavier Cullen each recorded 13 aces in 2025, the first players to reach that mark. Each man had ten aces entering the final round at Wisconsin Adventure, and each added three at that course--Xavier at the 6th, 12th, and 16th, and Derek at the 9th, 16th, and 17th. Derek had 10 more in 2026 to join Mick Cullen as the only MCMM players with consecutive tournaments with double-digit aces.

Karen Kemnitz famously recorded the 1,000th hole-in-one in M.C. Mini Masters history by acing the 2nd hole at Libertyville in 2005. It ended up being the only hole-in-one recorded at that hole in all the years it was in the tournament as Libertyville Sports Complex, though Andrew Miller aced it when the course was reopened under the name Aloha Falls in 2012.

Nate Blazier, a 2013 rookie, recorded the 2,000th hole-in-one in M.C. Mini Masters history when he scored the first-ever ace at Congo Falls' 14th hole. It came one hole after Blazier fell victim to his first-ever MCMM six.

Xavier Cullen, making his 10th Mini Masters appearance in 2019, recorded the 3,000th hole-in-one in MCMM lore by acing the 5th hole at Wild West, becoming the first player in tournament history to record a hole-in-one at that hole.

Derek Hartmann, in winning his first Ugly Jacket in 2025, also scored the 4,000th Mini Masters ace, at Kristof's 8th hole!

The most holes-in-one ever by the Most Sixes champion was 6, by Lisa Curran in 1997 and Michelle Arf in 2007. In 1997 Lisa had 24 sixes, which still stands as the tournament record (equaled in 2004). Three Most Sixes champs went without an ace-- Mary Kemnitz in 2003, Conner Altergott in 2019, and Zacchaeus Gola in 2021.

Mick Cullen was first to record at least one hole-in-one for each hole number (1-18). He completed the 1-18 perfecta with holes-in-one at Kristof's 7th and 9th holes in 2004. Matthew Cullen completed his 1-18 resume with an ace on the 12th at Par-King Red in 2009. Jason Gola joined the club in 2011. Josh Altergott, Dianne Cullen, Karen Kemnitz, & Tom Schweiss all finalized their lists in 2013. It would be eight years before anyone else joined them, but Xavier Cullen and Julie Schweiss checked their final numbers off to achieve this accomplishment in 2021. Dan Lee and R.J. Dusak then completed their 1-18 lists in 2023, and 7-time champ Michael Cullen joined them in 2024.  Derek Hartmann and Rusty Silber joined the club in 2026, with Derek setting a new record for the fastest to the complete 1-18 list--38 rounds!

The first player who managed at least one hole-in-one on the first nine courses that were used at the Mini Masters was Stephanie Altergott, who completed her run by acing the 18th at Ballybunion in 2005. Aaron Hanson, Karen Kemnitz, Tom Schweiss, and Jason and Maria Gola all joined her in this club by recording aces at Rocky's Fun House in 2006, while Michael Cullen and R.J. Dusak did the same in 2007.

The first player to record an MCMM ace at eleven different courses was Michael Cullen, when he scored holes-in-one at both Par-King courses in 2008. Michael also became the first player to record aces at twelve different MCMM courses by scoring a one at the 17th of Rocky's Fun House in Waukegan in 2009. Jason Gola matched the feat with a hole-in-one at Par-King Black in 2010.

Karen Kemnitz raised the bar by becoming the first MCMM player to record holes-in-one on 13 different courses in the tournament. Kemnitz scored an ace at both Congo Falls and Congo Rapids in 2013 to become the first to reach 13.

Matthew Cullen became the first to have holes-in-one at all 14 courses in Mini Masters history when he scored aces at Aloha Falls, Congo Falls, and Congo Rapids in 2014.

Karen Kemnitz and Matthew Cullen both reached the 15-course mark in 2015, when Kemnitz had an ace at both Wisconsin Adventure and Wild West while Matthew managed a hole-in-one only at Wisconsin Adventure. Mick Cullen joined the 15-course club with two aces at Wisconsin Adventure in 2016. Matthew Cullen became the first to move to 16 in 2019 by getting an ace at Wild West in his fifth attempt at the course.

Jason Gola joined them with 16 when he earned a hole-in-one at both Congo Rapids and Harry Semrow. After a couple more appearances by Congo Falls, Jason finally became the first player with MCMM aces at 17 different courses when he holed the 3rd hole at Congo Falls in one shot in 2023.

Josh Altergott was the only player to ace all three of the original par-4 holes in tournament history-- Congo River's 14th, Action Territory's 12th and 15th. He aced the two AT holes in the same round in 2002, one of two players ever to accomplish the feat (along with Mike Houck in 2003). However, despite being six under par on those two holes, both Altergott (48) and Houck (60) finished over par in their respective rounds. Houck, even more bafflingly, had no other under-par holes that entire round.

Karen Kemnitz joined Altergott with albatrosses at three different par-4 holes when she became the first MCMM competitor to record an ace at Wild West's 1st hole, in 2015. When Aloha Falls' 12th hole became a par-4, there was an opportunity for someone to become the first person with double eagles on four different holes, but no one achieved the feat before Aloha Falls closed in 2020.

Continuing the Altergotts' propensity for hole-in-one feats, Stephanie was the first player to have four holes-in-one on the same hole in her career, doing so at Lighthouse's 18th in a six-year span. She has since added a fifth (2009), but...

Michael Cullen became the first with five aces at one hole when he finished Kristof's 1st hole with a single stroke in 2007.

Mick Cullen is the only player with more than six holes-in-one on one Mini Masters hole, with 10 aces in 22 attempts on Lighthouse's 16th hole. The only other player with at least 8 aces on a single hole is Matthew Cullen, with 8 of his own on the same hole his brother has owned. Jason Gola is right behind with 7 aces on Lighthouse's 16th. No one else has more than 6 aces on any single Mini Masters hole.

The only two instances of a player acing the same hole five consecutive times are Mick Cullen on Sisolak's West's 18th hole and Matthew Cullen on Lighthouse's 16th.

The most holes-in-one at any hole that has not allowed more than one ace to any individual player belong to the 18th hole at Kristof's, which has allowed 22 ones to 22 unique players. Among current MCMM courses, the distinction falls to the 15th hole at Par-King Black, which has allowed 19 holes-in-one to 19 different players.

The final hole-in-one at Libertyville before it closed in 2007 belonged to 2007 rookie Jake Heynis, who aced the 18th while finishing in the first group to play the final course that year. After Jake's ace, no holes-in-one were scored by any of the six remaining groups playing on the back nine. The first hole-in-one recorded at Libertyville was by Skip Landt, playing on the 1st hole in 2002. (The course reopened under the name Aloha Falls in 2012, only to close again in 2020.)

Only three Sisolak's East holes allowed multiple aces to one player in the seven years the course was in the Mini Masters: the 4th (Matt Cullen 3), 14th (Mick Cullen 3) and the 18th (10 people with 2 or more).

Karen Kemnitz became the first player to reach double digits in Wacky Aces by scoring her 10th such hole-in-one with a broomball broom at Par-King Red's 3rd hole in 2019. She added an 11th with a broomball broom at Congo Rapids' 1st hole in 2024.

Libertyville/Aloha Falls didn't allow multiple aces at one hole to the same player until its 8th year in the tournament, when Jason Gola aced the 15th for the 2nd time. After 14 years in the Mini Masters, it allowed multiple aces on one hole to only seven players. Only Gola managed multiple holes-in-on1 on more than one hole at the course. On the other hand, Ballybunion allowed 2 aces at its 18th hole to Tom Schweiss despite only being in the tournament for two years, and Andrew Miller owns the only two aces at Congo Falls' 6th hole in the two years it appeared in the MCMM.

The single-round record for holes-in-one is five, recorded six times. Stephanie Altergott was the first, carding five aces at Lighthouse in 2006. She aced 3, 4, 10, 11, and 13. The hole-in-one at 13 was only the 4th in tournament history, and the ace at 10 was the first. This is the only time in history that a MCMM player has had back-to-back aces twice in one round. Stephanie would go on to have nine holes-in-one in the 2006 tourney, just one shy of what was then the single-day record.
The second time the feat was accomplished was 2010, when Ursula Cullen aced 3, 5, 8, 15, and 18 in the first of the day's two rounds at Sisolak's West. Her other five aces that day gave her 10, tying her for the single-day record at the time. In 2012, Mark Mason recorded five aces in his very first Mini Masters round, setting a new course record for Action Territory. Mason would record seven more holes-in-one in his other five rounds that day to tie the all-time MCMM single-day record.
Jason Gola joined the elite club in 2013 with five holes-in-one at Lighthouse, the only course to allow more than one five-ace round in MCMM history. He capped the round with a free-game-winning hole-in-one on the 18th.
Astoundingly, none of the first four players who scored five aces in a round managed to post the low score in the field for that course in that tournament year.
In 2018, two players scored five aces in a round, both en route to MCMM-record rounds of 33, each winning the trophy for that round. Mick Cullen had five aces at Wisconsin Adventure to post the first 33 in MCMM history in round one, while Tom Schweiss used three aces on the first three holes of Par-King Red to propel himself to five for the round as he tied Mick's record of 33 set earlier that same day.
Ralph Freye became the newest member of the five-ace club with a handful of holes-in-one at Congo Rapids in 2024, including two on par-3 holes, en route to a round of 40.
