Adama, who had earlier become the only Nigerian swimmer to reach the semi-finals, finished sixth in Semi-final 2 after clocking 22.44 seconds, bringing an encouraging Commonwealth Games campaign to a close.
Australia's Jamie Jack won the race in 21.55 seconds, ahead of Canada's Joshua Liendo (21.61) and Australia's Flynn Southam (21.86). Singapore's Mikkel Jun Jie Lee finished fourth in 22.25, while the Bahamas' Lamar Taylor claimed fifth in 22.30, edging the Nigerian by just 0.14 seconds.
The 17-year-old had secured his semi-final berth earlier in the day after advancing from the heats, becoming the lone Nigerian swimmer to progress beyond the opening round. His teammate, Clinton Opute, was eliminated in the heats of his event.
Adama also competed in the men's 100m butterfly, finishing seventh in his heat with a time of 55.81 seconds. Fellow Nigerian Colins Ebingha placed sixth in the same heat in 55.45 seconds, narrowly missing qualification for the semi-finals.
Although he fell short of a place in the medal race, Adama's performance marked another significant milestone for Nigerian swimming on the Commonwealth stage.
The teenager arrived in Glasgow as one of Africa's brightest swimming prospects after becoming the first Nigerian to win a medal at the World Aquatics Junior Swimming Championships in Romania, where he claimed silver in the men's 50m butterfly and broke the national record twice on the same day.
His run to the semi-finals of one of the Commonwealth Games' most competitive sprint events further highlighted his growing potential and offered fresh optimism for the future of Nigerian swimming, adding to Team Nigeria's encouraging start to the Games.
