$50 NL - 99 in CO facing 2 short stack pushes

[allrightfine]

UTG is 75/50 after 106 hands. He just lost 3/4 of his stack on previous hand and is obviously tilting. MP just sat at the table. I have no idea what his range is, but I don't really care since he's pushing only half what UTG pushed with.

I reraise to isolate because the effective stack on my left is only $38, but there are 3 more players to act.

If play is standard given reads, how should I have played this if effective stacks on my left were 100+ bb?

thanks!
