Tony McCoy equalled Martin Pipe's career tally of 4,191 winners with a typically powerful ride to get On The Record home first at Uttoxeter.
The record-breaking jump jockey drove the evens favourite over the line first in the 32Red On The App Store Handicap Hurdle, but only after a tough tussle with Bangkok Pete.
The 25-1 outsider pushed On the Record all the way and the race could have gone either way from the final flight.
However, McCoy got the Jonjo O'Neill-trained six-year-old, owned by his boss J P McManus, home by a neck much to the delight of his supporters.
"I made hard work of it. I was a bit conscious we went steady. Down the back I thought I'd better get him a bit closer because he's not a quick horse," McCoy told At The Races.
"Then he just started to wander about and have a look and was probably going to win over the last but decided to stop and it was only when a horse came by him that I got him going again in time thankfully. It's nice that he won.
"I've had a few steering jobs and I was hoping one would win and this horse was appropriately named. It's nice that it's one of Jonjo's and one of JP's.
"The thing with me and Mr Pipe is that it's just a personal thing. We've a lot of friends and there's been a lot of banter for a long time.
"I wouldn't be surprised if he went to Newmarket for a trainer's course. I hope I've driven him mad!"
On The Record was McCoy's second ride of the afternoon at the Staffordshire track after Zip Wire had failed to trouble the judge in the 32Red Casino Novices' Hurdle won by Nathans Pride.
McCoy recorded his fastest-ever 50 last month at Worcester and the 19-times champion is pushing towards 300 winners this season having recorded 289 victories in 2001-2.
McCoy has been targeting Pipe's all-time tally since chalking up his 4,000th winner at Towcester in November.
The record-breaking rider was formerly Pipe's stable jockey but has been retained by owner J P McManus since 2004.
Pipe was champion trainer 15 times until he handed over the reins to his son David in April 2006.
The latter tweeted: "Could there be a more appropriate way for @AP_McCoy to join my father in the 4191 club than success aboard On The Record?!"
McCoy could not overtake Pipe with his last ride at Uttoxeter as his mount Dashing Over faded out of contention behind Bumble Bay (12-1) in the £10 Free Bet At 32RedSport.com Standard Open National Hunt Flat Race.
He then left the track by helicopter for Worcester's evening meeting where he had four chances to surpass his former boss.
McCoy has to wait a little longer to beat Pipe's total after he drew a blank at Worcester's evening meeting.
The closest he came was when finishing second on Old Pals Act for the McManus/O'Neill combination in the Tonbrie Construction Handicap Chase.
He was third on My Nosy Rosy in the Green Lighting D-Lux Led Dimmable Downlights Mares' Maiden Hurdle, unplaced on Crannaghmore Boy in the Lifeboats Saving Lifes At Sea Selling Handicap Hurdle and last of four on Think Out Loud in the Green Lighting P-Lux Led Lantern Handicap Hurdle.
