LONDON — Defending champion Grigor Dimitrov was locked at one set all with American Sam Querrey in the first round of the Queen's club Wimbledon warm-up tournament when bad light ended play on Monday.
The 24-year-old Bulgarian, seeded sixth, was outgunned by 2010 Queen's champion Querrey in the first set and fell a break down in the second before rediscovering his touch to level a match which will be completed on Tuesday.
Four-times champion Lleyton Hewitt of Australia lost 6-7 7-5 6-2 to South African Kevin Anderson on his 16th and final appearance at Queen's.
The 34-year-old Hewitt, a former Wimbledon champion, served for the match in the second set, but Anderson, the world number 17, fought back and will face Nick Kyrgios or Stan Wawrinka in the second round.
