Mariners-Angels DTS kicked by BR

[whitecane]

I saw it with my own eyes tonight at Safeco. Dropped third strike, muffed by Angel's catcher Mathis, off his chest down the first baseline into (BR) Adrian Beltre's feet as he's running to first. No way did Beltre intentionally kick the ball as he didn't even see it coming. The ball bounces wide, Mathis picks it up and wings it into right field. As Beltre is rounding 2nd headed for 3rd, PU (Kerwin Danley) is signaling "OUT" which ends up being the call. Is it the correct one?

I thought without intent on the BR's part, this play was a "nothing". Am I misremembering?
