The second round contest between the number one players of the two countries never rose to the level it was expected to as the Chinese made it too easy for the Indian with his never-ending errors.
Wu looked out of sorts and it took Somdev just 62 minutes to seal a place in the last-eight stage of the ATP Challenger event at the R K Khanna Tennis stadium.
It was first meeting between 96th-ranked Somdev and Wu, who is placed 212 on the ATP ranking charts.
Wu struggled with his first serve right from the outset and his unforced errors pegged him back. The game was of the liking of Somdev as it involved long rallies from the baseline.
