The other three main draw matches Monday all went three sets.
Andreas Vinciguerra slipped by Daniel Brands 7-6 (8-6), 6-7 (5-7), 6-4; Fabio Fognini rallied for a 6-7 (7-9), 6-3, 6-4 win over Filip Prpic; and Pere Riba topped Peter Luczak 4-6, 6-2, 7-6 (8-6).
Vinciguerra, a local favorite, was a runner-up in the Swedish Open in 1999 and 2000. His win Monday moves him into the second round against top-seeded Robin Soderling, another local player.
