Actually, the pitcher's upper arm isn't traveling at 95 mph, but with the
leverage of his external limb, wrist, hand, and digits he can achieve 95 mph
at the tips of his fingers when the ball is released. Stick an atlatl at
the end of his hand and you get even greater velocity thanks to the leverage
of the atlatl. The energy that propels the object is provided by the
thrower's muscles, the velocity is increased by leverage.
With a universe that is expanding at an accelerating pace, we have to assume
that there is some "muscle" that is still providing energy to increase the
rate of expansion. Who knows, perhaps the energy source ended and a
universe-sized atlatl is still whipping around because of the original
energy imparted by the big bang.

OK, assuming that much, why wouldn't simple inertia account for
current observations about the accelerated speed of expansion
of the universe ? That is, throw a baseball and for a time its speed
is far greater than the speed of the pitcher's arm movements
that released the ball. Yes, it begins to decelerate after a distance
but not until X distance has been traversed.
Um , yes.
If for no other reason that a pitcher stands on a mound which is
a foot or so higher than the playing field.
Really obvious if the pitcher was standing on top of a mountain peak
in the Sierras. The force of gravity would add acceleration to the speed
of the ball, at least for X distance. And all this is about is the distance
"X."
But is a pitcher's arm really zooming along at 95 mph when getting set
to throw a ball ? That is a typical speed for a ball thrown by a
major league pitcher. Seems to me this is also about
the multiplier effect of leverage.

Um, no. At release, the ball is moving exactly as fast as the fingers that
propelled it. After that, it slows down due to friction, unless gravity is
accelerating it downwards.
If the universes is accelerating after "release", something is effectively
"pulling" it.
