Mutamam produces the goods Alec Stewart pulled off one of the training performances of the season to produce Mutamam fit and ready to win the Group Two Princess of Wales`s Pearl and Coutts Stake at Newmarket yesterday.Plans for his reappearance are still in abeyance, but Coral Eurobet reacted sharply and slashed his price from 25 to 1 to 8 to 1 for the King George VI And Queen Elizabeth Diamond Stakes (Ascot July 28th). Hills go 16 to 1 from 20 to 1.Stewart needed a brave horse on his side, Mutamam having been very ill in the spring and having his first run since November 4th.Richard Hills played his part, giving the six-year-old a splendid ride, sending him into the lead with two furlongs to run and keeping him going strongly to hold the challenge of Little Rock by one and a half lengths.Stewart was quick to point out that it had been a team effort in the yard in getting Mutamam back on a racecourse, and added: 'He had gut-ache in the spring, but it was not colic, it was a build up of infection.'
