Ivo Karlovic pulled Croatia level in their Davis Cup first-round clash in Japan on Friday.
The 6ft 10in star served 18 aces as he dominated against the higher-ranked Kei Nishikori, winning 6-4 6-4 6-3 to leave the tie level at 1-1 after the first day's play.
It was a day of upsets in Hyogo with Go Soeda producing a memorable comeback in the first rubber to put Japan in front.
He was trailing Ivan Dodig, a player ranked 35 places higher in the ATP rankings, by two sets to love before storming back to post a 6-7 (3/7) 3-6 6-4 6-3 7-5 success.
