Galaxy Blaster is coming in hot ahead of the Temora Cup heats and it's all thanks to losing part of his manhood.
With wins in his last four starts, and five of his last six, Galaxy Blaster heads into the feature series in career-best form.
Trainer Brian Smith is thrilled with his improvement since joining his kennel at The Rock.
"He's improving with every run," Smith said.
"He had a testicle taken out and has won five of his last six since he had it out.
"It was in his groin and I reckon it was affecting him so I ran the owner asked him and he said to go for it."
Part of his winning streak was success at Temora over the 457-metre trip.
After drawing box three in the second of five cup heats on Sunday, Smith can't see why he can extend his picket fence.
"He had his first run at Temora and went 26.03 over the 457 and I reckon the dog is probably three lengths quicker than what he was then," he said.
"He is going real good."
Smith also expects he will be better for the experience on the track.
His only failure was at Bathurst and The Rock trainer admitted it was definitely a race to forget.
"He did everything wrong," Smith said.
"It is a different sort of track, he had box four and absolutely walked out.
"He then got barreled at the first corner so everything went wrong in the cup heat so I didn't take any notice of that run.
"I just let it go and every since then he's just gone away with it."
Smith and wife Joanne also line up Tammin in another cup heat.
She was second to her kennelmate when they clashed at Temora, but after drawing box four Smith is far from confident.
"She has a very hard race and wouldn't have much hope," he said.
"She goes good there but there is a couple of real good dogs in there."
While Galaxy Blaster extended his winning streak at Wagga on Sunday, Smith had Tanami Express suffer his first defeat at start five.
However he was too disappointed considering an average start.
"Initially I was disappointed but if you watch the replay he walked out of the boxes, which I can't work out why," Smith said.
"If you put it together his run was pretty good to only get beat two lengths as he got knocked around a couple of times.
"I've got a couple of issues with him but if he hadn't of walked out of the boxes like he did he would have won the race."
