PDC Stats Analyst Christopher Kempf assesses the top ten PDC stars - based on their last 200 legs played - ahead of this weekend's German Darts Grand Prix in Munich.
#1 Averages - Josh Rock
#1 OChE - Gary Anderson
#1 Doubles - Gian van Veen
#1 171-180 - Josh Rock
#1 99, 101+ Checkout - Gian van Veen
After more than six months on top of the Form Guide, Luke Littler has finally ceded the 200-leg averages lead to a player only a few years older than he - Josh Rock.
Rock - having been denied a second ProTour title of 2025 in a deciding-leg loss to Gerwyn Price last week - nonetheless put the 110 average he recorded in the final to good use in boosting his averages to 101.63, the highest figure yet recorded for the Northern Irishman.
The 24-year-old has also become only the third player to have more than 100 three-treble visits to his name within his last 200 legs.
At the beginning of April, Rock was on a 96.6 average in the Form Guide - respectable, but still outside the top ten in an extremely competitive PDC field.
Rock has since added five points to his average and 9.4 points to his OChE rating, making April a memorable time of innovation and renewal for him thus far.
Under any other circumstances, averaging 97 and throwing 94 maxima over 200 legs would represent a dream come true - but after Littler's remarkable first three months of 2025, those figures represent a decline in form unusual for the teenager.
Though he is still the second most likely player in the PDC to throw a 180, Littler's finishing has let him down recently, and his rivals have capitalised on that defect in his armour.
With only the 47th highest doubles percentage in the PDC, Littler's slight decline in scoring (from throwing as many as 110 maxima in 200 legs) has allowed his opponents to win three of their last five matches against the World Champion.
After hitting the vast majority of his double 10s in the World Championship, moreover, Littler has managed barely 40% since.
The 18-year-old can still expect to win 60.3% of his legs against average ProTour opponents, but after touching an OChE rating of 70 earlier this year Littler is playing to a standard well below his best, even if 'well below' is enough to demolish the vast majority of other PDC professionals.
The two men over 50 years of age on the Form Guide are enjoying great success at the time of a changing of the guard within the PDC's young talent.
Jonny Clayton secured another PDC title with an authoritative campaign in Players Championship 14, which saw 'The Ferret' win each of his matches by at least four legs and eliminate other veteran players in Michael van Gerwen and James Wade.
After falling as many as five points behind his World Cup partner Gerwyn Price, the two men are now only one point apart, and Clayton's fifth-highest OChE rating and second-best doubles percentage arguably put the two on approximately even footing.
Gary Anderson, aged 54, has also made his mark in April, earning two consecutive quarter-final appearances on the Players Championship circuit.
Anderson is now the most efficient player in the PDC. While Rock - who averages one point more than Anderson - translates it into winning 64.5% of legs, Anderson does more with less, winning 66.2% of legs on a 100.77 average.
Elsewhere, Players Championship 14 runner-up Dominik Gruellich is not the player anyone would have anticipated challenging Clayton in the final of a Players Championship event.
While on first glance the stats would not have expected him to get there either on an 87.90 average, the German upstart has defeated both of the Premier League players he has faced this year, and over-performed his ordinary stats in order to do it.
Thanks to averages of 99 in a 6-3 victory of Chris Dobey and 95 to eliminate Rob Cross, Gruellich has raised his level to the utmost when facing the PDC's most respected and decorated players.
If his 2025 record against lower-ranked ProTour opponents like Berry van Peer and Tytus Kanik has been less than stellar - leaving him with a rank of 102 in averages over his last 200 legs - he has more than atoned for that with a £10,000 payday and memorable victories against quality opponents.
*OChE (Ordinal Checkout Efficiency) explained:
OChE is a metric designed to evaluate the efficiency at which players convert their averages into legs won.
The statistic is the % of legs a player would expect to win on the ProTour, calculated from a weighted average of 4,5, 6 & 7 visit checkout rates.
