I saw this scenario being discussed on another ultimate forum and I
thought I'd bring it here to make sure I got the right answer.
The disc is thrown to a tall Player O1 who is standing in the end
zone. O1 is defended by a short defender D1 who can jump really
high. When D1 leaps up to make a play on the disc O1 taps the disc
directly upward so that D1 cannot make a play on the disc. O1 jumps
and lands in the exact same spot and then catches the disc in that
same spot. O1 admits that the purpose of the tapping of the disc was
to keep the disc away from D1.
What should be the result of the play?
My first thought was the relevant rule is "purposeful bobbling
(including tipping, delaying, guiding, brushing or the like) to
oneself in order to advance the disc in any direction is considered
traveling."
It seems to me that O1 did not "advance the disc" since he stayed in
the exact same spot on the field. If that is the correct
interpretation then I believe O1 scored a point.
But then I read on the online version of the rules
http://www.usaultimate.org/resources/officiating/rules/11th_edition_rules.aspx
that "tipping the disc for the purpose of evading a defender would not
be legal." Does that mean that in this example O1 is "advancing the
disc" upward? That seems odd. If not, what rule would make “"tipping
the disc for the purpose of evading a defender” illegal in the case
where the offense doesn’t change their location?
If O1 has travelled then what happens?
I believe the relevant rules are:
"A goal is scored when an in-bounds player catches any legal pass in
the end zone of attack, and retains possession of the disc throughout
all ground contact related to the catch."
"Completed pass: Any catch that results in the team in possession of
the disc retaining possession"
"If a team gains or retains possession in the end zone that they are
attacking other than by scoring a goal in accordance with rule XI, the
player in possession must carry the disc directly to, and put it into
play at, the spot on the goal line closest to where possession was
gained."
"[travelling] results in a stoppage of play and a check"
My interpretation:
Since the catch is part of any "completed pass" and the catch was not
legal (it involved a travel) then O1 has not caught a "legal pass" and
does not score. So O1 stops play, and checks the disc where he caught
it (allowing D1 to tap the disc). Then O1 walks the disc to the goal
line and "puts the disc into play" (which involves a ground tap).
Am I right?
P.S. I apologize for not citing the rule numbers but the numbers
don't show up for me when I view the rules online.
