At certain situations it is more feasible than hitting the ball further. Like, say, when you want your man from 1st base to second before you have to go to first base yourself...
Though I only know the rules for Finnish baseball, which is somewhat different from American baseball.
Which doesn't change the fact that all that is completely irrelevant considering the actual subject of this topic...

So, in order to make an F-14 fighter function in a vacuum, it should be updated with:
-advanced life support systems, including fully pressurized and sealed cockpit section OR a TIE-Fighter style combat suit, whichever floats your boat
-oxidizer for the fuel burned by engines (you'd have to replace at least half of the fuel tanks in the plane with LOX tanks, which is not as simple as it sounds because liquid oxygen is either very very cold or very very high pressurized and in applications like this it is both)
-Very good insulation for fuel tanks to prevent freezing, and most likely you'd need heaters in the tanks as well
-attitude thrusters to be able to control the ship
-advanced radiators or huge heat sinks to absorb the excess heat produced by the engines and other systems in the plane
-updated radar systems adapted to see FS/FS2 ships, should there be something special about them.
That's it, you're set. Now your F-14 can fly in space, at least until it runs out of fuel and oxygen. Different thing is what it would need to do a scratch on Amazon.
The easiest way would be toreplace the original missiles with Harpoon missiles. It wouldn't carry many of them, but it could destroy a drone without problems should it have them. This solution wouldn't have a need of huge-ass reactor to produce energy for some FS/FS2 era weapon.
Anyway. It wouldn't really be F-14 anymore. It's maneuverability would be dependant of the attitude thruster system implemented on it. The main thrusters would generate the same thrust as on earth, if you could provide oxygen onto them... and they would generate quit an acceleration, should the world of FS use real life physics... but it doesn't, so the conversation is actually quite useless anyway.
It would win or lose depending on how good you want to make it.

And I believe the mentioned Sukhoi fighter with inverted wings is Sukhoi-47 Berkut (Golden Eagle in English).
