Mogakolodi Ngele netted a brace while Joel Mogorosi scored once as Botswana thrashed Eritrea 3-1, and the Zebras emerged 5-1 winners on aggregate over the Red Sea Camels.
The 2018 FIFA World Cup qualification (CAF) first round second-leg clash was played at the new Francistown Stadium in Francistown on Tuesday night.
The home side came into encounter leading 2-0 on aggregate, having defeated Eritrea in their own backyard in the first-leg clash in Asmara on Saturday afternoon.
The Zebras made their intentions clear from the outset dominating possession, and pressing the Red Sea Camels in search of an early goal.
Nine minutes into the game, Botswana midfielder Kabelo Seakanyeng dribbled past his marker, before playing a good cross into the Eritrea box, but it was cleared away at the near-post.
The two goal scorers from the first-leg, Galagwe Moyana, and Joel Mogorosi combined four minutes later, and the latter placed his header just inches wide of the target.
However, in the 16th minute, Eritrea launched a quick attack from the right, and Moussi Negassi's cross was headed home by Henok Goitom as the Red Sea Camels took a shock 1-0 lead.
The Zebras continued to push forward, and they were awarded a free-kick on edge of the Eritrea box on the right in the 23rd minute. Mogakolodi Ngele stepped up, and equalised from the set-piece with a curling effort.
The home side doubled their lead five minutes later through their inspirational captain Mogorosi, who rose highest inside the Red Sea Camels' box to head home Moyana's cross.
Eritrea captain Goitom nearly restored parity three minutes after the half hour-mark after dribbling past Botswana defender Tebogo Sosome, and forced goalkeeper Kabelo Dambe into a fine save at his near-post.
At the other end, gifted forward Ngele burst through the Red Sea Camels midfield, and unleashed a powerful shot which was parried away by keeper Minasie Weldezgi in the 39th minute.
Zebras striker Hendrick Moyo missed a sitter a minute before half-time, after receiving his teammate Seakanyeng's cross unmarked inside the Eritrea box, but he placed his shot narrowly wide of the target.
Five minutes into the second-half, Botswana pushed forward with Seakanyeng's cross finding Moyo in the Eritrea box, and the quick striker hit the upright with his low attempt, and the ball went out for a goal-kick.
The Red Sea Camels launched a rare attack on the hour-mark, and midfielder Yonathan Solomon's cross from the left was headed straight into Botswana shot-stopper Dambe's hands by Goitom.
With minutes left on the clock, Zebras substitute Kaone Van Der Westhuizen's cross was headed onto Moyo's path by another substitute Segolame Boy, and the striker forced Weldezgi into a comfortable save.
Botswana dangerman Ngele grabbed his second goal of the night, and sealed the Zebras' 3-1 victory, with a sublime half volley from the edge of the Red Sea Camels' box.
Botswana emerged 5-1 winners on aggregate over Eritrea. The Zebras will now take on Mali in the World Cup qualification second-round in November, 2015.
