WSH@LAD: Detwiler leaves the game with ankle injury

SAN DIEGO -- It looks like left-hander Ross Detwiler will not go on the disabled list, according to manager Davey Johnson. However, Detwiler will miss his scheduled start on Monday against the Giants because of a right oblique strain.

Johnson said the oblique is getting better and it's possible Detwiler will miss just the one start. If it continues to get better, Detwiler will play catch Tuesday. Then Johnson will start lining him up for a return to the rotation.

Left-hander Zach Duke will take his spot in the rotation Monday.

Zim to host 'A Night at the Park' on Thursday

WSH@SD: Zimmerman's two-run shot gets Nats on board

SAN DIEGO -- Hosted by Nationals third baseman Ryan Zimmerman and the ziMS Foundation, the fourth annual "A Night at the Park" will be held Thursday starting at 6 p.m., at Nationals Park and will feature a special performance from alt-rock group Third Eye Blind.

Nationals Park will be transformed into an intimate concert hall for 2,000 guests, as a custom stage is built on the outside concourse of the Presidents' Club, with attendees sitting in the Diamond Club seats. The evening will also include silent and live auctions.

The ziMS Foundation is dedicated to the treatment and ultimate cure of multiple sclerosis by funding comprehensive support and educational programs. MS is a disease close to Ryan's heart. In 1995, his mother Cheryl was diagnosed with MS, a chronic and unpredictable disease that affects the central nervous system.

The ziMS Foundation has donated more than $1 million to MS support programs and research.

Limited tickets, event details and additional information about the foundation can be found at www.anightatthepark.com

Lombo looking to get comfortable at plate

WSH@SD: Lombardozzi knots game with an RBI single

SAN DIEGO -- In his last 21 games, Nationals infielder Steve Lombardozzi is 7-for-53 (.132). Last year, he was one of the most consistent hitters on the team. It helped that he played often and managed to finish eighth among rookies with 105 hits. Lombardozzi said he is currently trying to get comfortable at the plate.

"I'm trying to get my timing right and not trying to do too much," he said "It's a combination of getting some at-bats finally. I'm getting a chance to play now. I haven't done nearly as well as I've liked to. I'm working on it. I'm starting to feel better."

Lombo, who got the start at second base on Sunday against the Padres, showed signs of life at the plate, going 1-for-3 with an RBI in Saturday's 2-1 loss to the Padres. He drove in Kurt Suzuki for the tying run in the sixth inning with a single.

Worth noting

• Manager Davey Johnson gave shortstop Ian Desmond the day off, which was planned since early this week. Danny Espinosa made the start at shortstop on Sunday against the Padres.

• Bryce Harper missed his second straight game because of a sore left knee. He hopes to be back on the field by Monday against the Giants.
