Tommy Haas loses to Donald Young, Marinko Matosevic slump continues

Donald Young proved too good for veteran Tommy Haas in the Citi Open first round on Monday as Marinko Matosevic suffered another loss.

American left-hander Young eased past 37-year-old wildcard Haas 6-3 6-4 at the Washington hard-court event.

Haas, the former world number two, battled a shoulder injury late in 2014 and early this year, having only made his return in June.

The 2012 runner-up has only won two main-draw matches in 2015, including at Wimbledon, as his return continues.

Haas' two wins almost matches that of Matosevic, who went down to Belgian Ruben Bemelmans 6-3 6-3.

The Australian qualifier is a former world number 39, but his ranking has plummeted to 169 in the world after his struggles.

Matosevic has only three ATP World Tour main-draw wins this year, and the last of those came in Acapulco in February.

Qualifiers endured a difficult day at the ATP 500 tournament.

Yoshihito Nishioka went down to Alexander Zverev 7-6 (7-1) 6-3, Darian King was thrashed by Go Soeda 6-2 6-1 and Ryan Harrison fell to James Duckworth 6-1 7-6 (7-4).

Russian Teymuraz Gabashvili battled past Benjamin Becker 4-6 6-1 6-3 and Ricardas Berankis was a 7-6 (7-1) 6-3 victor over Lu Yen-hsun.

Victor Estrella Burgos, who turned 35 on Sunday, edged wildcard Nicolas Jarry 4-6 6-3 6-4, and Chung Hyeon thrashed Dudi Sela 6-2 6-1.
