While at UWIC, Holgate played for the university rugby team, UWIC RFC, in the WRU Division One East. After a short time with UWIC, Holgate received a call-up to the Philippines rugby sevens team for the 2007 SEA Games in December 2007, having qualified by virtue of his mother's Filipina heritage. The team reached the final, but lost 29–14 to the hosts, Thailand. This was soon followed by appearances for the Philippines national XV in the inaugural Asian Five Nations tournament in July 2008; he scored a try in the team's 101–0 win over Brunei and also played in a 20–8 win over Guam as the Philippines won the Pacific-Asia division.[4][5] He played again in the 2009 Asian Five Nations, but suffered an ankle injury in the Division 3 semi-final against Iran that kept him out of the 25–0 win over Guam in the final.[6][7] The 2010 Asian Five Nations saw Holgate compete for the Philippines in Division II. He played on the wing in the 53–33 semi-final win over Thailand,[8] before the Philippines went on to beat the hosts, India, 34–12 in the final to secure promotion to Division I.
Zhermack Badia
Holgate graduated from UWIC in 2010 and subsequently signed for Zhermack Badia of Serie A, the second tier of rugby in Italy. During the 2010–11 season, he scored seven tries in 18 appearances. The season culminated with Holgate being named in the Philippines squad for the 2011 Asian Five Nations Division I in Ansan, South Korea.[9] He played at outside centre in the semi-final against South Korea, but despite a good performance, he was unable to prevent a 34–20 defeat.[10] However, in the third-place play-off against Malaysia, Holgate scored a hat-trick of tries as the Philippines secured an 86–20 win to retain their Division I status for the 2012 tournament.[11][12]
Kyuden Voltex
After a year in Italy, Holgate signed for Japanese club Kyuden Voltex, who, at the time, played in the second tier of Japanese rugby.[13] He made his debut in a 22–7 friendly win over Meiji University on 12 June 2011.[14]
Holgate was part of the Philippines Sevens team that qualified for the 2013 Rugby World Cup Sevens tournament in Moscow, their first appearance in the tournament.[15] After a three-week training camp,[16] Holgate was named in the Philippines final 12-man squad for the tournament.[17] Holgate played in all three of the Philippines' Pool C matches against Kenya, Samoa and Zimbabwe, making history against Kenya by scoring the Philippines' first ever try in the competition.
