"She's got such a good attitude and takes her race very well.
"She's been a great flagship for the yard. We'll have a chat and see where we go with her now."

"No-one wanted to make it (the running) so we thought we'd let him enjoy himself.
"It's nice to get his head in front."
Horizontal Speed was the second leg of a double for Hobbs, whose Milosam brought up the hat-trick in the totepool Mobile Novices' Handicap Chase.

Hobbs said: "He stayed very well and it ended up being a three-mile Flat race."
O'Brien said: "My lad just got a bit idle. He wasn't doing a stroke on that ground.
"It didn't suit me without the fences, but hopefully he can keep going."
