The Yeti Untamed provides a solid coverstock matched with the same core properties as the original Yeti. It comes at a polished box finish and, despite its shine, offers plenty of hook.

We matched up best with the Yeti Untamed on our medium test pattern. The ball offered moderate length with a big hooking motion. The Untamed is not as angular down lane as the first Yeti, but it is easily a few boards stronger. Cranker almost saw too much hook from this powerful ball on this pattern. He was forced left pretty fast, but was still able to stay in the pocket.

The sport pattern was the pattern we went to next and the Yeti Untamed handled it with very few problems. Usually polished covers give us trouble because of the strong reaction at the back end, but the Yeti Untamed was a more blended shape. The strength of this cover easily provided us with enough hook and, at times, made this pattern look almost like a house shot.

Cranker was the only tester able to use the Yeti Untamed on our heavy oil test pattern. His higher rev rate allowed him to play straighter down the lane and let the strength of the Yeti Untamed take over at the mid-lane and back end. Our other two testers needed a little help on this pattern. They removed the polish with a 2000 SiaAir pad to give them earlier traction on this heavier volume of oil.

Moving to the dry pattern, Tweener and Stroker had a better reaction than Cranker. They were able to move farther left and open up their angles in the front, feeding the ball farther outside and watching it hook right into the pocket. Cranker saw too much hook from his Yeti Untamed on this pattern. He would need a ball with the pin closer to his axis to tame down the reaction on this shorter pattern.

Performance Ratings

Despite a coverstock change from a pearl on the original Yeti to a polished solid on this one, the Untamed offers a big change of direction down lane. This shape was best on our medium test pattern.
The polished coverstock has moderate length. The low RG core and the solid coverstock keep the ball from skating past the breakpoint.
Back End17
We had just as much back end from the Untamed as we did from the original Yeti. The big difference we saw was an increase in total hook.
Total Hook51
The Yeti Untamed will provide users with more hook than the Yeti and any of the Torrid line. This ball adds more total hook to the strong back end motion of the original Yeti.


Even with a shiny box finish, this ball had no problem hooking plenty on our medium pattern. Bowlers who bowl on a little slicker THS will like being able to throw a polished ball without giving up total hook.


Low rev players will struggle on heavy volumes with the Yeti Untamed at the box finish. Removing the polish immensely increased our Stroker’s reaction on this pattern.

Overall Summary

The Yeti Untamed takes the reaction from the first Yeti and adds more motion in the midlane which equates to more total hook. This ball will be useful on a wide spectrum of lane conditions.
