Actually, IFR could apply to a liner. It's a judgement call by the ump. The key thing is that the ump recognizes that a player has an opportunity to klank a routine fly or liner, in order to get a DP, and calls that before the catch is made.

Yep. See Bill Russell’s deliberate clank, (NOT called by the ump), in the ‘78 Series attempting exactly what you describe with Reggie Jax in ‘no man’s land’, (Should I stay or should I go now....), just off of first. Remember it? Lasorda went NUTZ!!!!!!!

You normally see that only on a slowly hit line drive.

Actually, here's the definition of an Infield Fly quoted directly from the official rules of Major League Baseball (I bolded the item for line drives):

An INFIELD FLY is a fair fly ball (not including a line drive nor an attempted bunt) which can be caught by an infielder with ordinary effort, when first and second, or first, second and third bases are occupied, before two are out. The pitcher, catcher and any outfielder who stations himself in the infield on the play shall be considered infielders for the purpose of this rule.

Ah, but you forget that the infield fly rule can't be called when there's only one base runner. You have to have runners at first and second or first, second, and third. There was just one guy on first this time.
