Did I make the right call here?

8 players left in 20 person tourney. I have about 9000 which - due to a fast structure - is a bit above average. Blinds are 300/500 and I've been playing tight.

I raise in MP to 1,500 with 85o - trying to mix it up. SB goes all-in with 4K straight. So, with my bet (1500) his all-in (4000) and the BB (500) there's 6000 in the pot and I have to call 2500 wo win the pot of 6000.

My read: He's a pretty solid player, but he's short-stacked. I think 10% of the time he's going to have an overpair (99 or better), 5% of the time he'll have an over and a card between mine (like A6) and 85% of the time he's going to have 2 overs.

If I put him on 2 overs, aren't I getting the correct odds to call? Calling 2,500 to win 6,000 is 2.4-1, right?
