The 29-year-old Harambee star played for 78 minutes as Castle Thunder ended the season with another trophy in Thailand
Kenya international Ayub Timbe concluded the season with his third trophy after Buriram United beat Prachuap 4-0 in a one-sided Thai League Cup final at Leo Stadium on Sunday.
Prior to the match, the 29-year-old had helped Thunder Castle clinch the Thai Premier League title and a week ago played for 68 minutes as they beat Nakhon Ratchasima 2-1 in the FA Cup final.
Against Prachuap, Timbe was started by coach Masatada Ishii, but it was DR Congo striker Jonathan Bolingi who stole the show after netting a brace with goals in the 35th and 61st minutes.
Second-half substitute Peeradon Chamratsamee then added the third in the 90th minute before Suphanat Mueanta wrapped up the emphatic victory in the 94th minute.
Timbe was in the thick of it in the sixth minute when he was tackled by Bolingi, but his first left-footed effort was knocked in by goalkeeper Jirunpong Thamsiha.
It was Buriram who dominated the proceedings in the opening 20 minutes and they finally broke the deadlock when Bolingi, 27, sneaked the ball past Thamsiha.
Despite being the dominant team, Buriram entered the half-time break leading 1-0 and they came back for the second half a more determined team.
However, they were forced to wait until the 69th minute when Bolingi doubled their lead after latching on to a Supachok Sarachat cross.
Eight minutes later, Prachuap was reduced to 10 men after Saharat Pongsuwan was shown a red card for a clumsy tackle.
Timbe was then pulled off for Mueanta in the 78th minute and on full-time, Chamratsamee powered home the third before Mueanta hit the fourth to the death.
Timbe, who joined Buriram as a free agent from Japanese side Vissel Kobe, managed 13 league appearances in total, scoring two goals and providing two assists.
Before joining Vissel Kobe in March 2021, Timbe made 26 total league appearances for Chinese top-flight side Beijing Renhe, scoring nine goals and providing four assists.
