The shorter the name becomes, the longer his collection of tries. Two more in the home win over Leinster extended the Scarlets' winning start to the Guinness PRO12 season - a fourth straight win matched only by Munster and Edinburgh. A South African who emigrated as a teenager to the Canadian prairie with his family, DTH has wasted no time moving higher up the all-time PRO12 try-scoring table.
Three more will take him to 40, a figure exceeded by only three other wings - Tommy Bowe (62 from 138 starts for Ulster and Ospreys), Tim Visser (58 from 96 for Edinburgh) and Andrew Trimble (42 from 125 for Ulster). DTH's 37 from 69 starts puts him one ahead of Connacht's Fionn Carr.
Despite making the long haul from the west of Scotland to west Wales, Canada's left wing finds himself in the same reassuringly natural habitat, at the same altitude in the top two.
He spent virtually all last season there with the Warriors, signing off in suitable style, scoring the second of Glasgow's four tries in their glorious Guinness PRO12 Final win over Munster in Belfast. And who should be next on DTH's hit list at the Parc y Scarlets on Friday night? Munster.
Even at this early stage in the campaign, it promises to have a serious impact on the long race to the play-offs. For the first time since way before the creation of the Celtic League, Munster are having to make do without their totemic second rows, Donncha O'Callaghan and Paul O'Connell with almost 450 Munster matches between them.
While one was making his debut in the Aviva Premiership and the other found himself reduced to the role of helpless bystander as Ireland came to the end of another Rugby World Cup road, Munster responded as if their European Cup-winning locks were still in harness.
They jumped to the top of the table thanks to a bonus-point win over Cardiff Blues in Cork. Last season's beaten finalists are already six points better off than they were at the same stage last year after losing both opening home fixtures, to Edinburgh and the Ospreys.
The Warriors welcomed back their battalion this week from Scotland's stirring World Cup campaign in time for Friday's assignment in Dublin against the other Guinness PRO12 club who made roughly the same towering contribution to the Irish cause, Leinster.
Scotland picked 16 players from the Guinness PRO12 champions. Ireland had used the same number from Leinster until the final nine minutes of the quarter-final against Argentina when Rhys Ruddock, called into the squad for the injured Peter O'Mahony, entered the fray as a 71st minute substitute for Jordi Murphy. In doing so, he took Leinster's Rugby World Cup total to 17.
Ulster's contingent are back in Belfast where their native province face the Blues on Friday night. While the Arms Park club make a second successive trip across the Irish Sea, Connacht travel in the opposite direction to Swansea and a collision with the reinforced Ospreys.
Nobody has been scoring tries like Connacht over the first four rounds - three against the Dragons, four in Glasgow, five against the Blues in Galway and five more against Zebre in the same city last week.
Those 17 tries, distributed amongst no fewer than eleven different players, have brought enough bonus points to put Pat Lam's team just one point behind Munster despite losing one match, in Glasgow by a single point.
Edinburgh, by contrast, have managed no more than eight but, unlike Connacht, they are four from four and eager to make it five from five against Zebre in Italy on Saturday. Scotland's capital team have underlined their ambition by signing Test flanker John Hardie.
In beating off what must have been serious competition for one of the leading lights of Scotland's World Cup, Edinburgh have captured a Highlander from Super Rugby who was born and bred on the family farm way down near the bottom of the South Island of New Zealand.
Scotland coach Vern Cotter contacted Hardie early in the summer, raising the possibility of a run-out during the pre-World Cup matches but making no promises. He did so after the SRU's recruiting officers had discovered the player's ancestral eligibility.
Hardie's grandmother had emigrated to the far side of the world from Culross in Fife as a child 90 years ago. She lived to reach the grand old age of 97, passing away before she could see her grandson make his Scottish debut as a second half substitute against Ireland in Dublin two months ago.
His contributions to the national cause highlighted by tries in the crucial wins over Japan and Samoa, Hardie would surely have been preparing for a World Cup semi-final against Australia but for that controversial late penalty which the game's governing body, World Rugby, conceded had been awarded by mistake.
