keep highest value using proc sort

[RebeccaJW]

data raw; set rawdata;
     keep day year title number;
proc sort data=raw nodupkey; by day year; run;

How could I modify this code to keep the day and year with the highest number if raw data contained multiple different values of numbers, instead of just a single value?

Thank you!

data raw; set rawdata;
     keep day year title number;
proc sort data=raw ; 
by day year descending number; run;

data want;
set raw;
by day year;
if first.year;
run;

Would the above work?
