England batsman Ollie Pope started the 2019 campaign with a career-best 251 before Surrey's bowlers struggled in their Champion County match with MCC.
The 21-year-old, who won two Test caps last summer, added 68 to his overnight 183 to help Surrey reach 520 all out.
Teenage debutant Jamie Smith was removed early on for 127 by MCC captain Stuart Broad (2-83) in Dubai, ending a fifth-wicket stand of 266 with Pope.
Dom Sibley's unbeaten 102 then took MCC to 221-1 at stumps, a deficit of 34.
Warwickshire openers Will Rhodes and Sibley put on 190 for the first wicket in MCC's second innings before Rhodes was bowled by Scott Borthwick for 88 late on.
Earlier Pope, who did not play on England's winter tours of Sri Lanka and West Indies, gave a reminder of his talent as he brought up a maiden double-century.
In the midst of a sandstorm, Pope went on the charge after passing 200 and went to 250 by launching Dom Bess for back-to-back maximums.
He was eventually dismissed in the next over when he skied Rhodes to Sibley at mid-off, having hit 23 fours and six sixes in a sublime 297-ball innings.
However, MCC's resilience with the bat second time around means the game is now likely to finish in a draw.
Following the conclusion of the match on Wednesday, Surrey host Durham University on Thursday, 4 April, and then start the defence of their County Championship title against Essex at The Oval a week later.

Such is the impact that Ollie Pope has made that you tend to forget that this is only the start of his second first-class season.
He looked every inch the England batsman, in that he constructed his 251 against a very good MCC attack including Stuart Broad.
Every time he walks to the middle he looks assured and this innings was full of positive footwork and strokeplay.
Every test that has been put in front of him so far he has passed and it is only a matter of time before he is pulling on an England shirt again.
He has also proved here in Dubai that he can bat in all conditions including sand, as most of his double hundred was made in the middle of a sandstorm.
