Tyner Junior off the mark Seventeen year old amateur jockey Jack Tyner rode a winner on his first ever ride, on his father's Robert Tyner's Square Sphere, in the concluding Munster By 5 Against The All Blacks Mares Bumper at Limerick today. Tyner produced the point to point winner to lead a furlong out before staying on well for a five and a half length win over Ella Watson. Cork based Tyner Snr was absent, attending a point to point.
