Cashner returns from DL to face Nats

( - Andrew Cashner returns from the disabled list on Saturday when the San Diego Padres continue a three-game set with the Washington Nationals at Petco Park.

Cashner has been shelved since May 17 with soreness and irritation in his right elbow. The 27-year-old right-hander had a 2.35 ERA and 47 strikeouts in 57 1/3 innings before the elbow problems arose. However, he was only 2-5.

Cashner has faced Washington eight times (3 starts) and is 2-2 with a 4.87 ERA.

Getting the call for the Nationals on Saturday will be righty Blake Treinen, who hasn't started since losing to Pittsburgh back on May 22 and is 0-2 on the year with a 1.40 ERA Treinen's last start was skipped following a rainout on Tuesday so that the rest of the rotation would stay on turn.

In Friday's opener, Tanner Roark had a career-high 11 strikeouts over eight innings and Washington Nationals blanked San Diego, 6-0.

Roark (4-4), who snapped a three-start losing streak, allowed three hits and didn't walk a batter. Roark has pitched 17 scoreless innings against the Padres this year, allowing only six hits with 19 strikeouts against one walk in two starts.

"He's been pitching like that for us all year," Nationals manager Matt Williams said. "He continues to pound the zone with all his pitches, pretty impressive."

Denard Span walked to start the game and Anthony Rendon, celebrating his 24th birthday Friday, followed with a homer to left, as the Nationals posted their fourth straight win.

Tyson Ross (6-5) surrendered five hits and six runs -- five earned -- over 5 1/3 innings for the Padres, who have just four hits over their last two games. It was the ninth time they were shut out this season.

"Tyson's stuff was good, but he made a mistake to Rendon in the first inning," Padres manager Bud Black said. "He got outpitched, bottom line."

Washington split a four-game set with the Padres in D.C. earlier this season.
