Heres from the book Bowling Execution
Cup-and-Collapse Release
Numerous players on the PBA Tour use a technique I call the cup-and-
collapse release. Del Ballard jr. heads the list of contemporary bowlers
whose deliveries lit this category. Chris Barnes and Sean Rash also feature
this type of delivery.
This delivery can be performed in two manners: using a free swing or
using a controlled or semicontrolled swing. In a free swing, you place the
ball into the pushaway and let it fall into the backswing due to gravity`s
pull on the ball''s weight. At the top of the backswing, cup your wrist and
maintain this hand position until the release point. Then, collapse your
wrist and drive the ball into the lane. This type of release creates a heavy
roll and presents great strike potential.
In a controlled cup-and-collapse release, the ball rests back in the palm ol
the hand at the beginning of the stance. it is drawn back with a bent elbow,
which remains bent throughout the swing At the release point. the wrist
collapses, and the lingers drive the ball into the lane. Although this is the
ultimate method for staying under the ball, it can take a toll on the hand, wrist,
and elbow. it can also affect the knees and legs. A number of PBA players can
trace injuries to the strenuous exertion of the controlled cup-and-collapse
release. This method of execution, in great part, curtailed and possibly ended
the career of former touting player Bob Vespi. it also sidelined Mike Miller,
whose thumbless delivery placed severe strain on his wrist and knees.
Many players who have been blessed with a great release have failed to
take advantage of this gift. Again, a great release is not the guarantee of
successful bowling. Average releases delivered at ideal release points-
along with accuracy and balance-are the principal ingredients for a
top~quality bowling game.
