With Johnny going 3:53 this weekend and his dad having a 3:51 PR, are they now the fastest US miler father-son duo?

What is Matthew Centrowitiz Sr's mile PR?

Looks like 3:59.2, so no where close to the Gregoreks.

From a thread on LRC back in 2011.

3:58.8 Barry Brown

3:58.35 Darren Brown

3:54.94 Matt Centrowitz

3:57.92 Matthew Centrowitz

3:56.7 Sam Bair Jr

3:59.72 Sam Bair III

Looks like the Gregoreks might be fastest ever, surpassing Kip Keino and son (3:52.72 avg).
