Joseph O'Brien completed a quick short-priced double in the colours of John Magnier when The Crewmaster landed the Bulmers Live At Leopardstown Maiden.

The Mastercraftsman colt was sent off a 4/6 shot in the ten furlong contest after a promising runner-up effort on his debut at Galway.

He was asked to quicken into the lead a furlong-and-a-half from home and kept on well in the closing stages for a three-and-a-quarter length success.

"He had a nice run first time when he finished well up the hill. He came on from it and won well today," said Joseph O'Brien.

"The slow pace probably helped me as I was probably in a better position than some.

"He has a good attitude and hopefully the handicapper won't kill him. He's a big horse and took a bit of time to get to the track. I liked him."

O'Brien had also partnered Lieutenant General to success in the preceding juvenile maiden at odds of 4/5.
