A surprise trip home for Christmas has landed Adelaide-based Chris Caserta a double at Caulfield with the apprentice winning two races for Darren Weir.

Caserta topped and tailed Wednesday's meeting winning the Alan Wicks Handicap aboard betting ring drifter Twitchy Frank then ending the day on Silentz in the Ladbrokes Handicap.

Originally based in Melbourne, Caserta is now indentured to Tony McEvoy in Adelaide.

Trainer Darren Weir called on Caserta's claim of 2kg to reduce Twitchy Frank's 62kg when his regular go-to apprentices, Ethan Brown and Lachie King, were not available.

Caserta has ridden winners for Weir in Adelaide and got his start with the stable riding in trials while suspended before transferring to Adelaide.

He was thrilled to get the call-up to return home and surprise his mother on Christmas Day.

“I thought I would be riding at Morphettville today but when I got the call-up to ride here on Boxing Day I thought I'd come over early,” Caserta said.

“Dad looks at my rides every two minutes and he would have known I was coming over, so I made sure he didn't say anything.

“Mum got a nice little surprise when I walked into my uncle's house.”

Caserta was also thankful to McEvoy for allowing him to visit Melbourne and ride for an outside stable on Wednesday.

“The McEvoy team have shown me a lot of support and I can't thank them enough,” Caserta said.

“I'm pretty pleased with how things are going and I'm just starting to hit my straps now.

“It was a bit of a slow process the first couple of months but I've signed for another three months over there and hopefully if that goes well, I'll transfer completely.”

Weir praised Caserta's ride on Silentz who gave the leading trainer a treble for the day.

“That was a great ride,” Weir said.

“I don't know how he ended up on the fence from where he drew, but he did everything spot-on.

“Full credit to him.”
