The Glasgow prop used to play a bit at centre in his school days and he showed he still has an eye for the break as he stepped the Dragons' defence to go in for the try.
After the match Alex said: "It was a good win, especially down there where the crowd are really vocal, and it was good to get back on track after a hard couple of weeks.
"It's always good to get over for a try, it's one I'll look back on and remember. I may need to do a few pick-and-goes to get back into the front-row union, but it's all good fun.
"I used to play a bit at 12 in my school days. We have a big game against Zebre next week, there is a lot to build on, we have a lot of leaders in the team and they stayed calm when we went behind.
"We have a wide range of ages, Corey [former All Black hooker Corey Flynn] keeps the average age to a normal limit by himself, but it is good to see a few of the younger players getting a chance."
