Boxing on the undercard of Carl Frampton's loss to Leo Santa Cruz, the 26-year-old from Prestonpans went the distance for the first time.
The Commonwealth super-lightweight champion now has eight wins since turning professional.
Despite being deducted a point for low punches he won by 78-73 on two cards and 79-72 according to the third judge.
Taylor described the experience of fighting in Las Vegas as "brilliant", but felt he did not hit top gear in the ring.
"It was far from my best performance," the Scottish fighter said. "I was a little bit too eager to impress on the big stage.
"I felt a little bit tight and tense. I couldn't get my footwork going, couldn't get flowing. I never felt like I was in any danger, I felt very comfortable in the fight. I felt like I never got out of second gear.
"He was very awkward, very hard to nail clean. When I did catch him he was very good at spoiling me. It was a good learning fight for me and to good get the eight rounds in."

Jaguar Land Rover has discontinued the famous off-road vehicle, which has been exported across the world.
More than two million have been made since the original Land Rover Series began production in Solihull in 1948.
Plans to bring in stricter measures for new car emissions by 2020 meant there were "certain conditions the Defender just won't meet", the company said.

The last Defender: Is Land Rover's off-road heyday over?
More on the Defender and updates from Birmingham and Black Country
A "big turnout" of "cheering workers and media everywhere" accompanied the completion of the last Defender at about 10:00 GMT, said BBC Midlands Today's transport correspondent Peter Plisner.
"It's the death of an icon," said Simon Collins, Warwickshire and West Midlands Land Rover Club secretary.
There were cheers and sadness this morning as we witnessed the last Defender roll off the production line after almost 70 years; the longest-running production car in the world.
We heard about a family in which three generations had worked on the Defender and the Series of models before it. Some workers also chose today to retire rather than transfer to other parts of the plant.
All 700 employees who worked on the Defender were invited to a farewell event to the iconic model. Land Rover also brought in some of the vehicles from the past. It was quite a send-off.
Motoring journalist Quentin Willson said the Defender would live on.
"With some 70% of Land Rovers ever built still around we will still be able to cuddle them and see them on the road. And while we can shed a tear, there are still lots and lots of Land Rovers," he said.
A replacement model for the Defender is being developed, said the manufacturer.

It currently has an outstanding balance of £7.7m to pay between now and 2045 - 30 years after the first trains ran between Tweedbank and Edinburgh.
However, it has now agreed to borrow money to pay off the balance in a move estimated to save about £4.3m.
Council leader David Parker said it would reduce the burden on local tax payers.
He said the local authority had access to very low rates on its borrowing.
"When officers have looked very carefully at the financial issues around it, it makes sense to make that saving," he said.
"That is exactly what we will be doing now.
"For future councils we are reducing the revenue burden on them and making sure that the railway contribution is paid."
Josh Taylor remains unbeaten after a comfortable points victory over Alfonso Olvera on his Las Vegas debut.
