The 21-year old former Indiana University star, who was picked up with the 11th selection in the 2011 MLS SuperDraft, showed why there are such big wraps on him with a trio of neat finishes in the Dynamo's 4-1 home win over DC United.
The first came in just the 4th minute when he received a perfect through ball from Geoff Cameron before slotting it past DC keeper Bill Hamid before the visitors responded through Marc Burch six minutes before half-time.
But Bruin was on the spot to make it 2-1 just a couple of minutes later when he headed home Brad Davis' sublime cross from the left before completing his hat-trick just before the hour-mark with another header from a Davis free-kick.
Cam Weaver wrapped up proceedings in the 62nd minute with Houston's fourth as they climbed to third on the Eastern Conference table.
