Here we can observe that the verb used doesn't reflect the correct tense to express when this action took/is taking/will take place. There are many tenses where you could choose from, depending of the time of action:
Tenses: Simple, Progressive, Perfect, Perfect progressive
Times: Past, Present, and Future

<span>Tommy, in an effort to maintain clowning's positive roots, invites dancers to weekly performance battles.</span>
