Top 30-and-overs, juniors to play this weekend

   Some of the top 30-and-overs and juniors in the nation will play in separate tournaments this weekend in the Sacramento area.

   The men's seeds -- No. 1 Clayton Almeida of West Palm Beach, Fla., No. 2 Jan Tiilikainen of Reno, No. 3 Michael Kwong of Woodland and No. 4 Robert Stang of San Francisco -- received first-round byes and will play in the quarterfinals at noon.
   Almeida, 33, won the USTA 30 Hard Court Championships in Austin, Texas, in March. Tiilikainen, 42, has won the 30 Indoor singles title four times, most recently in 2011.
