A subordinating conjunction (subordinators or subordinate conjunctions) is a part of speech which is used to connect or ‘juncture’ a dependent clause to independent clause. They are important parts of complex sentences as they also introduce adverbs.

In the sentence, ‘however’ is used because the person can do the act, but there is a limitation to his action and that is ‘not throwing a ball very well’.
