How about this example

$ cat test1.txt
Belmont,8-Oct,
1st,6.0F,-->More data fields
1st,6.0F,-->More data fields
1st,6.0F,-->More data fields
$ awk 'NF==1 { a = $0 ; next } \
{ print a $0 }' test1.txt
Belmont,8-Oct, 1st,6.0F,-->More data fields
Belmont,8-Oct, 1st,6.0F,-->More data fields
Belmont,8-Oct, 1st,6.0F,-->More data fields
