Ryan Zimmerman grounded a go-ahead single off the shin of Pittsburgh reliever D.J. Carrasco in the seventh inning and the Washington Nationals, still buzzing after Stephen Strasburg's dazzling debut, beat the Pirates, 7-5, last night.

A night after a sellout crowd of 40,315 watched Strasburg strike out 14 Pirates in winning his big league debut, only 18,876 fans came to Nationals Park. They witnessed the first major league appearance by Pittsburgh's Brad Lincoln, the fourth overall pick in the 2006 draft.

Lincoln, promoted from Triple A Indianapolis after Tuesday night's game, allowed five runs on seven hits in six innings. He struck out three and walked two.

Lincoln also had two hits and drove in a run.

It was 5-all when Cristian Guzman singled in the seventh off Carrasco (1-2) and moved up on Nyjer Morgan's sacrifice bunt. Zimmerman hit a grounder that struck Carrasco on his follow-through and caromed into short rightfield.

Adam Dunn homered for the second straight day as Washington handed the Pirates their seventh consecutive road loss. Pittsburgh has dropped four straight overall.

Drew Storen (2-0) worked a scoreless seventh for the victory. Tyler Clippard pitched the eighth and Matt Capps got the final three outs for his 20th save.

In other games:

* At Cincinnati, leadoff man Orlando Cabrera got the NL's top offense going with three doubles and a single and Aaron Harang rebounded from his shortest start of the season, leading the over the San Francisco Giants, 6-3.

Cabrera scored three times, Scott Rolen hit a pair of RBI doubles and Jonny Gomes drove in three.

Harang (5-5) gave up five hits and two runs in seven innings. The righthander lasted a season-low four innings in his previous appearance.

* At Milwaukee, Derrek Lee hit his 300th homer, Marlon Byrd and Geovany Soto each connected twice and the Chicago Cubs showed some surprising pop to power past the Brewers. 9-4.

Chicago's five homers marked its biggest outburst this season.

* At New York, the game between the San Diego Padres and New York Mets has been rained out.

The Padres and Mets will play a day-night doubleheader today. The games will start at 1:10 p.m. and 7:10 p.m.

Noteworthy

* Milwaukee Brewers catcher Gregg Zaun says he'll have season-ending shoulder surgery on Tuesday, which will likely finish the veteran's short stint in Milwaukee and maybe his career.

Zaun signed as a free agent this offseason for $1.9 million and immediately took the Brewers' starting job. The 39-year-old switch hitter started 0-for-21 at the plate before building his average to .265, with two homers and 14 RBIs, before tearing the labrum in his shoulder.

* The Pittsburgh Pirates have recalled their top outfield prospect, Jose Tabata, after he batted .308 with three home runs and 25 stolen bases at Triple A Indianapolis.

First baseman Jeff Clement was optioned to Indianapolis to make room for Tabata.

* San Francisco Giants outfielder Mark DeRosa will have more tests on his left wrist to find out what's causing the numbness in his hand.

DeRosa will see a specialist in San Francisco today. He's been sidelined since May 9. He was on a minor league rehabilitation stint when he began feeling numbness in the left hand again.

* Struggling Chicago Cubs third baseman Aramis Ramirez was placed on the 15-day disabled list to rest his ailing left thumb in the midst of his season-long slump.

It's the latest blow in a disappointing year for Ramirez, who has hit .168 with five homers and 22 RBIs. Ramirez says he hurt the thumb while swinging in May against Cincinnati and pain and swelling has lingered ever since.

Infielder Chad Tracy was recalled from Triple A Iowa to take Ramirez's place on the roster.
