The former London Wasps centre showed no ill-effects from a whistle-stop trip with the England Sevens squad to get on the end of a break by Andy Goode and Aaron Mauger to score the 67th-minute try which put Tigers ahead at Kingsholm.
It was a reaction thing, Goodey made a half-break and offloaded to Aaron, I just tried to get to his outside, shouted and hoped for the pass, said Erinle.
As important as it was, the 27-year-old also had work to do in some determined Leicester defensive work throughout 80 pulsating minutes.
As a collective, we defended very well, said Erinle, who played in the Barclays Churchill Cup with England Saxons last summer. There was some excellent work in defence and a try-saving tackle from Johne Murphy under the posts.
It was a great defensive effort from the whole team. Kingsholm is a very difficult place to win so we have to be pleased with the result.
Erinle started the season with a debut try at Bristol but has had to wait for his opportunities after some bad luck with injuries and the strength of competition for a place in the Tigers line-up.
I have been unfortunate with the timing of my injuries and I have got back into the team when others have been injured, he said. But you just have to take your chances.
Erinle went to the IRB World Sevens in New Zealand and then flew to the United States for the next leg, only to be called back to club duty for last weekend.
I was collecting my baggage in San Diego when I got the text about coming back to Leicester, he said. Id gone from 13 hours ahead of the UK in New Zealand to eight hours behind in San Diego and then home! It was confusing, but the win at Gloucester made it all worthwhile.
