Much like last night's game against Venezuela, the Tall Blacks came out of the gates firing - Webster knocking in two early triples as Paul Henare's side shot out to a 15-9 advantage.
However, offence was hard to come by from that point, with Mexico dredging out a 22-21 quarter-time advantage before an ugly second quarter played out.
With the Mexicans implementing a lot of zone looks defensively, the Tall Blacks struggled to break it down, scoring just 12 points in the second quarter as Mexico took a 38-33 lead into the break.
Some quick offence from Breakers duo Abercrombie and Webster saw the game quickly tighten back up in the third period, but Mexico stretched a two-point third quarter lead into a seven point advantage going into the final 270 seconds of play.
From there - Abercrombie took over, with his coolness at the line being complemented by his finishing inside, and his thunderous dunk capping off a brilliant individual display.
Webster finished with 15 points on 6/12 shooting, while Isaac Fotu was also proficient at the line, going 7/8 from the charity stripe as he ended with nine points and seven rebounds.
But tonight was Abercrombie's night, and he'll have time to enjoy it - with the Tall Blacks getting a day off before taking on China at 11.00pm on Thursday.
