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:
The simplest example we could make is if this action is a routine that happens continuously, the action verb (invite) is changed to simple present for the third person of singular (invites):
<span>Tommy, in an effort to maintain clowning's positive roots, invites dancers to weekly performance battles.</span>
