"Dislodged" or not

[bigda65]

NFHS,

R1, ball hit to F5, boots, but finally throws to F4 who drops the ball.
R1 has slid well past 2nd, but on his way by, grabs the base and it comes up from the square mounting hole. The base is still in the mounting hole and is leaning slightly toward left field. (the base is still in the area of where it should be, it is just not flush with the ground) F4 picks up the ball and tags the runner before he gets back to the bag.

U1 calls R1 out on the tag. PU and U1 confer, U1 reverses call and puts R1 back on 2nd. No real argument either way and game continues.

Would the base be considered dislodged in this sitch??
