Team USA superstar Caeleb Dressel just put on another gold-medal performance -- this time, the Olympic swimmer did a drum cover of "Good 4 U" by Olivia Rodrigo ... and the dude's got skills!!
Of course, the 7-time gold medalist LOVES to bang on his drums all day (when he's not training his ass off) ... and has previously opened up about how he uses the beats per minute from his drum riffs to help with his stroke rate in the pool.
The 25-year-old showed off his talents with the sticks on Monday by playing along to OR's Billboard-topping hit track .
