Amakhosi were anything but the ‘Cup Kings’ of South Africa as they crashed out of a tournament in which they are the defending champions – and have reached five of the last seven finals.
For Arrows, it is another top scalp after they have already beaten Orlando Pirates (1-0) and Mamelodi Sundowns (4-2) this season. Aside from Henyekane’s triple, Mokete Tsotetsi’s own goal summed up the visitors’ afternoon, while Arthur Zwane scored for Chiefs.
Henyekane opened the scoring inside four minutes with a clinical finish from just outside the area. Some neat play from Arrows was intercepted by central defender Jonathan Quartey, but he could only half-clear the ball into the path of the striker, and he side-footed home from 25-yards.
The lively Jose Torrealba and Zwane set up Gert Schalkwyk for a chance to equalise, but he skewed his shot wide.
A mix-up from a free-kick on the right handed Arrows their second on 22 minutes, as poor communication between goalkeeper Itumeleng Khune and his central defender Tsotetsi saw the latter head home as Khune came to collect a ball that was curling towards goal.
Zwane set up Torrealba in the penalty area, but the Venezuelan shot across goal and wide.
Arrows were 3-0 up on 28 minutes when Henyekane raced onto a through-ball and beat an advancing Khune with another neat side-footed finish.
Amakhosi coach Muhsin Ertugral had seen enough by this stage and he substituted Reneilwe Letsholonyane on the half-hour mark and replaced him with Thuso Phala.
The shambolic defending continued from the visitors as Onismor Bhasera was robbed in possession by Philani Shange, who raced to the byline and fed Abia Nale. The midfielder’s shot was saved by Khune.
Ertugral made his second tactical change on the first half on 36 minutes, removing Quartey and replacing him with Gerald Sibeko.
Tsotetsi almost made amends for his own goal just after halftime as he headed wide from six yards out.
Henyekane and Kagiso Dikgacoi both wasted chances to shoot, as Arrows sat back more in the second period, inviting Chiefs onto them, but then trying to catch the visitors on the break.
Henyekane completed his hat-trick on 72 minutes as he stretched to steer home a cross and leave Khune helpless on his line.
The Chiefs goalkeeper made a fine save from Shange diving low to his right, before Zwane scored a consolation for Chiefs with five minutes to go. Tshabalala set him free on the left and he cut inside, before unleashing an excellent shot from 30-yards that beat Helton da Rocha in the home goal.
