Mommsen hit 102 for Scotland against Namibia
Scotland's Intercontinental Cup match in Namibia ended in a frustrating draw after a rain-affected final day.
The hosts closed play in their second innings on 218 for four, 165 runs shy of the Scottish total.
Namibian opener Pikky Ya France finished on 63 not out, while Gerrie Snyman made 88 from 97 balls.
Scotland had earlier declared on 296 for five, having made 350 in their first innings, with Preston Mommsen and Ryan Flannigan posting centuries.
Momsen's 102 helped establish a 347-run lead for the visitors going into the final day in Windhoek, while Majid Haq contributed 59 and Kyle Coetzer hit 56, and further runs left the African side trailing by 383 when they took to the field.
In Namibia's first innings, Haq had taken six wickets for the loss of just 32 runs as the Scots skittled the home side out for 263, with Craig Williams top scoring with 51.
However, Haq could only claim a brace of wickets on the final day, while Richie Berrington added another couple from his eight overs.
On day one, Flannigan also scored 102 for his maiden international century, with Coetzer (62) again making a valuable contribution.
Scotland, who drew with Holland in their opening match of the tournament, earn six points on top of the seven for a tie courtesy of their first-innings lead.
But their total of 20 points after two matches is half that of early leaders Ireland.
