DOHA, Qatar (AP) — Rafael Nadal and Jo-Wilfried Tsonga opened their season Tuesday with three-set victories at the Qatar Open.

The second-ranked Nadal beat Philipp Kohlschreiber of Germany 6-3, 6-7 (2), 6-3. Sixth-ranked Tsonga beat Tunisian wild card Malek Jaziri 7-6 (5), 6-7 (5), 6-1.

Nadal has struggled with a sore left shoulder since the end of last season. The Spaniard looked headed for a routine victory against Kohlschreiber, but the 43rd-ranked German stepped up his net play in the second set and jumped to a 4-1 lead before evening the match. Kohlschreiber went up a break in the third but Nadal broke back and took control from there.
