What is Jake T Austin's middle name?

His full name is Jacob Austin Szymanski. The "T" stands for his mother Gina's maiden name which is Toranzo.

T stands for Toranzo, Jake Toranzo Austin Syzmanski. UPDATE BY SJHEERTS: if you watch Go Diego Go, my brother watches that, not me, if you have Direct TV, read the info, click on Cast and Crew, and it says Jake Toranzo Syzmanski as Diego. He is called Jake T. Austin because it's easier to pronounce
