Kenya Sevens are through to the quarterfinals of the second leg of the World Rugby Challenger Series currently ongoing in Montevideo in Uruguay.
Shujaa who were bottom of Group A after mixed results in their opening two matches needed to win their final match against Tonga to be sure of qualifying for the quarterfinals.

In the final preliminary game, Shujaa came through and secured a crucial 17-14 win over Tonga and thus qualify for the quarters.
Menengai Oilers star John Okoth dashed past Tonga's defence to score a center-post try that Tony Omondi successfully converted, giving Kenya a 7-0 lead.
Shujaa extended their lead when Kabras Sugar winger Lameck Ambetsa broke through on the right wing and offloaded to Nygel Amaitsa, who set up Omondi for a try at the right corner.
Tonga managed to narrow the gap just before halftime after a series of penalties, with Siaosi Huihui powering through for a converted try as Kenya led 12-7.
After the break, Tonga capitalized on Kenya's defensive lapse to take a 14-12 lead.
However, Shujaa had the last laugh again as Nygel Amaitsa scored Kenya's winner for a 17-12.
However, Kenya responded with a crucial try from Amaitsa, who dove over the try line after Benson Salem set him up with a well-executed switch in play.
Kenya finished second in the pool with six points, behind Portugal.
Shujaa will play Uganda in the quarterfinals.
