Ronnie O'Sullivan made safe progress into the second round of the inaugural World Snooker Tour Classic in Leicester, while there was a milestone for Judd Trump as he also advanced.
Seven-time and reigning world champion O'Sullivan saw off Egypt's world number 117 Mohamed Ibrahim 4-2, registering breaks of 137 and 104 along the way.
Trump's 4-1 victory over David Lilley saw him join O'Sullivan and John Higgins in an elite club - the only players in history to have made 900 career centuries.
That was achieved with a 113 that put him 2-1 against Lilley, and Trump later sealed the triumph with another to add to the tally, a 131.
Mark Williams edged past Sean O'Sullivan 4-3, Kyren Wilson was a 4-1 victor against Dean Young, and Jimmy White beat Graeme Dott 4-2.
World number 10 Luca Brecel was defeated 4-2 by Haydon Pinhey, an amateur from Plymouth who made two century breaks en route to victory.
Ryan Day, ranked 18th in the world, also exited at the hands of a player with amateur status, beaten 4-1 by Steven Hallworth.
