Johnson, a former two-time NCAA singles champion was an upset quarterfinal winner. The 24-year-old qualifier ousted sixth-seeded veteran Spanish left-hander Feliciano Lopez 6-3, 6-2 in 1 hour, 13 minutes on Friday.

Cilic, who has 10 career championships, including one in Zagreb earlier this month, has beaten Anderson in three of four all-time meetings. The 27-year-old Anderson is trying for his third career title.

The 2014 Delray Beach champ will earn $81,500.
