Alexander Zverev and Jannik Sinner march on in Vienna

Italian
Sinner
beat
home
hopeful
Dennis
Novak
6-4
6-2
to
set
up
a
tantalising
showdown
with
Casper
Ruud.

Should
he
win
that
match,
Sinner
will
move
ahead
of
Hubert
Hurkacz
in
the
race
to
qualify
for
this
year’s
ATP
Finals,
while
victory
for
Ruud
will
strengthen
the
Norwegian’s
standing.

“It’s
going
to
be
tricky,”
said
Sinner.
“He’s
in
a
better
position
than
I
am
for
the
race.
I
think
right
now
it’s
tough
to
say
and
tough
to
do
because
in
the
end
you
try
always
not
to
think
about
that,
but
in
the
end
you
think
about
that
because
you
believe.”

Zverev
was
given
a
sterner
test,
eventually
overcoming
Alex
de
Minaur
6-2
3-6
6-2
in
one
hour
and
42
minutes.
The
Olympic
gold
medallist
will
now
face
Felix
Auger-Aliassime,
who
fought
back
from
a
set
down
to
defeat
Cameron
Norrie.

That
feeling
when
you
get
your
300th
win
@AlexZverev
makes
it
to
the
quarterfinals
in
Vienna
after
defeating
de
Minaur
6-2
