The world number 2 star, who on Wednesday came back from behind to beat James Wattana, again struggled to find the fluent form which saw him win the International Championship in November last year.
Since that triumph, Trump has had little success on the baize starting with his defeat in the final of the Premier League to Stuart Bingham. His defence of the UK Championship title did not last long after he was knocked out in the first round in a surprise defeat to Mark Joyce and in the Masters he was thrashed 6-1 by Graeme Dott in the quarter finals.
And the Bristol star fell at the last 32 stage in Berlin suffering a 5-4 defeat to Nottingham’s Hamilton who managed to win a scrappy final frame to seal a place in the last 16 and will face Ali Carter for a quarter-final spot.
Hamilton’s victory was not the only shining light for the East Midlands city as fellow Nottingham pro Michael Holt had a day to remember after securing a place in the quarter finals. A brilliant 5-1 win over 2011 German Masters winner Mark Williams was then followed with a last 16 win over against Kurt Maflin.
Peter Lines, who recorded the result of the opening day beating John Higgins, continued his winning ways by beating another former world champion. This time Ken Doherty experienced defeat to the Yorkshireman despite at one stage leading 3-1 in their third round match. Lines plays Marco Fu on Friday for a place in the last eight.
Last season’s German Masters runner-up Stephen Maguire was sent packing his bags after a whitewash defeat against Mark King.
But King was unable to reach the last eight of the competition after falling to a 5-4 defeat against Welshman Matthew Stevens late in the eveing session.
Mark Selby continued his bid to win another major title after beating Joe Perry 5-2 and set up what could be a thrilling last 16 clash against Ding Junhui.
Australian Neil Robertson stormed into the quarter finals after comfortable wins against Michael Wasley and Andrew Higginson and Barry Hawkins showed the Berlin crowd why he should be a major contender for the title when he ended Mark Allen’s hopes in an impressive 5-1 win.
Friday sees the four remaining last 16 ties played out before all four quarter-final matches take place in the evening session.
By close of play on Friday only four players will remain as the business end to this season’s German Masters approaches.
