The first chance of the game fell to Prso eight yards out but
there was too much power behind the shot and he blasted over.
Prso then turned provider when he collected a Jeremy Clement
ball before passing to the feet of Nacho Novo but the striker failed to
connect properly and his weak drive was off target.
Kilmarnock had a decent chance when Wales whipped a dangerous
ball into the box and Danny Invincibile sent the header fizzing just
wide.
But only the heroics of goalkeeper Graeme Smith at the other
end kept the scoreline level when he blocked Prso's point-blank shot.
Rangers were rewarded for their hard work when they surged
into the lead after 22 minutes.
Adam pounced on a Prso lay-off before choosing his spot and
sending a thunderous 25-yard drive into the back of the net.
The midfielder could have grabbed a second goal almost
immediately but his cheeky chip fell just wide of the post.
Gers did not have to wait too long to double their advantage,
however, and were celebrating again just five minutes later.
This time Novo's effort produced a decent save from Smith but
he knocked the ball straight into the path of Boyd, who gratefully fired
home at the far post.
Killie made a change at the break, replacing Gary Wales with
Simon Ford.
And the defender had an immediate impact on the game when his
attempt to block a Novo effort almost ended up in the back of his own
net.
Boyd then drew gasps from the home crowd when his
opportunistic 25-yarder fell just inches over the crossbar.
The forward was content to act as provider for Rangers' third
goal instead, sending a long ball to the feet of Prso who squeezed the
shot home at the near post with 57 minutes gone.
Prso made way for Libor Sionko seconds later to rapturous
applause from the Ibrox fans, before Novo was replaced by Thomas Buffel.
Buffel could have provided the final flourish when he was
allowed to run half the length of the pitch unchallenged only to be
denied by a one-handed save from Smith.
A Sionko effort was then blocked by the feet of the Killie
keeper at the near post.
