I bet the turn here. Yes pot control is good with only Top pair, but you are beating so many hands that would call the flop bet and you are losing to only a few (KQ and 55). I think you lost value with that line.

If the pot was bigger preflop, lets say $4-$5 (because of a few preflop callers) i would like your line. however the betting would probably end up being, bet $3.50 on flop, check turn, call $6 bet on river.
