Champion jockey Glen Boss celebrated his birthday with a winning double at Sandown on Wednesday.

Boss, who turned 44, scored on the Mike Moroney-trained Bishops Castle in the Guinot International Handicap (1500m) and backed it up on Don't Get Excited in the New Zealand Bloodstock Handicap (1300m).

When reminded it was birthday, Boss said: "There are a lot of 44-year-olds who wish they were doing as well as me."

Bishops Castle ($7) defeated Half His Luck ($8.50) by three-quarters of a length with Flying Hussler ($5) 1-1/2 lengths away third.

Then after getting in-form favourite Don't Get Excited ($2.35) first past the post he was welcomed back to scale with a burst of Happy Birthday from excited owners.

The Stephen Theodore-trained four-year-old won in photo finish from Bass Strait ($4) with Haussmann ($6.50) a length away third.

Anthony Feroce, a representative for Moroney, said gear switches helped Bishops Castle.

"He tended to over-race so it looks like the gear changes worked," Feroce said.

A delighted Boss said a trial on Friday also took the edge off the four-year-old gelding.

"He is still learning his trade but he is winning or being very competitive," Boss said.

Leading trainer Peter Moody, fresh from three wins at Caulfield last week, scored a double with favourites Are There Any ($2.80) in the BMW Handicap (1400m) and Office Bearer ($2.05) in the Mistable Handicap (1000m).

Moody said Are There Any was closer to the end of her preparation than the start.

"It was a deserved win. Arguably she should have won her last two," Moody said.

"She is probably close to a break and getting ready for summer racing where she is realistically suited."

Of Office Bearer, Moody said the four-year-old was capable of winning over longer distances.

"He is a stakes-quality horse and is going to be better when he gets out to 1400 metres," he said.

He said there will be some nice options for him as the spring progresses.
