Czech veteran Radek Stepanek had a much-needed win at the Claro Open Colombia, while seventh seed Malek Jaziri progressed.
Radek Stepanek earned just his third ATP World Tour match win in 12 months, with a first-round triumph over Edouard Roger-Vasselin at the Claro Open Colombia.
Stepanek, 36, came into the ATP 250 event in 2015 with just two match wins - one via an injury retirement - at Tour-level since his run to the semi-finals in Bogota in 2014.
And he continued his touch in the high altitude city, registering a 3-6 6-3 6-4 victory over France's Roger-Vasselin.
Stepanek's lack of results has seen his ranking slip to 369 in the world, and he is playing in the main draw on a wildcard.
The clash had resumed with the pair locked at a set apiece, having been suspended on Monday due to rain.
Seventh seed Malek Jaziri emerged a 6-7 (5-7) 6-2 6-4 winner over Austin Krajicek, while American qualifier Alexander Sarkissian outplayed John Millman 6-3 6-3.
Millman's fellow Australian Matthew Ebden joined him as an early casualty, the latter losing to Tatsuma Ito 1-6 6-3 6-4.
Adrian Menendez-Maceiras saved two match points in downing Alejandro Gonzalez 4-6 6-4 7-6 (11-9), while Pere Riba was leading Daniel Elahi Galan 4-3 when rain halted play.
Brazilian qualifier Marcelo Demoliner also advanced past Illya Marchenko 6-3 7-5.
