Mallorca Open: Ruud into last 16 as Lajovic dumped out
The 22-year-old claimed a 6-4 7-6 (7-4) victory to set up a meeting with Tennys Sandgren in the next round.
Following Ruud onto Centre Court, the American beat Spain’s Jaume Munar 7-6 (7-3) 7-5 in just over two hours.
Sixth seed Karen Khachanov is also safely through, although he surrendered a set in beating French qualifier Lucas Pouille 7-6 (9-7) 3-6 6-4.
But Dusan Lajovic, seeded eighth, was not quite as fortunate.
Lajovic, ranked 41st in the world, was beaten 6-4 7-6 (7-2) by Slovakian qualifier Lukas Klein (ranked 256).
Feliciano Lopez came out on top of battle of Spaniards in the round of 32, beating Nicola Kuhn 6-1 7-6 (7-4).
