and Klawervlei Stud’s well-bred young sire ROYAL MO (Uncle Mo) has enjoyed a great strike rate with his runners over the past few weeks and the former G3 Robert B. Lewis Stakes winner came up with a third first crop winner at Kenilworth on Monday afternoon.

Royal Mo’s two-year-old son RULE OF THUMB was sent off favourite to land Monday’s fourth race, the Maiden Plate (1400m), and he duly obliged in smart style.

The Justin Snaith trained gelding hit the front 100m from home and he powered away to score impressively by two lengths.

Remarkably, sons of Royal Mo filled the first three placings in Monday’s fourth race, with Rule Of Thumb relegating his paternal half-brothers ROYAL PORT LOUIS and MATSUYAMO to second and third placings respectively.

Bred by Klawervlei Stud, Rule Of Thumb, who had finished third on debut before finishing second last time out, races for Messrs A J Brand and Jonathan Snaith.

He joins a growing list of promising winners for Royal Mo, with others including ROYAL AUSSIE and MO JIVE. This list looks sure to growing further in coming weeks, with Royal Mo now sporting the eye-catching statistic of having three winners and ten placed runners from just nine starters

A son of outstanding sire, and emerging sire of sires, UNCLE MO (Indian Charlie), Royal Mo’s granddam IRISH LINNET (Seattle Song) won no fewer than 19 races including the G2 New York Handicap.
