Nationals 2, Diamondbacks 0
PHOENIX -- Chad Tracy had two hits including a home run, while Dan Haren scattered four hits in seven scoreless innings to lead the Washington Nationals to a 2-0 victory over the Arizona Diamondbacks at Chase Field on Saturday.
Haren (10-14) struck out five, walked one and permitted only two runners as far as second base. He has won at least 10 games in each of the last nine seasons since joining the Oakland starting rotation in 2005.
Denard Span tripled and scored off Brandon McCarthy (5-11) to break a scoreless tie in the sixth inning, and Tracy hit his fourth home run of the season with one out in the seventh.
Tracy had 27- and 20-home run seasons for Arizona in 2005 and 2006. Haren had 37 victories in his 2 1-2 seasons with the Diamondbacks from 2008-10, including a career-high 16 in 2008.
Martin Prado singled, Miguel Montero walked and the runners moved up on a one-out wild pitch in the ninth inning, but Rafael Soriano got out of it for his 43rd save. He has not given up a run in his last 12 appearances.
Washington (86-75) has won two in a row to guarantee retiring manager Davey Johnson a career record of at least 300 games above .500.
Johnson is 1,372-1,070 in his 17 major league seasons.
Chris Owings had two hits for Arizona (80-81), which has lost five of its last six games to fall below .500 for the first time this season. The D-backs have scored 11-plus runs in their last six games and have been shut out seven times this season.
Span tripled on the first pitch in the sixth inning and scored on Ryan Zimmerman's groundout to deep shortstop.
McCarthy retired the first 11 batters he faced before Jayson Werth's two-out single to right field in the fourth inning.
Wilson Ramos walked and Chad Tracy singled with one out in the fifth, but McCarthy got out of it with two groundouts. McCarthy had walked one batter in his previous 46 innings before walking Ramos in a seven-pitch at-bat.
The Diamondbacks had doubles from rookies Chris Owings and Matt Davidson in the first six innings but did not get a runner past second base against Haren.
NOTES: Johnson will manage his last game on Sunday after announcing his retirement earlier in the season. He is a two-time manager of the year with Baltimore (1997) and Washington (2012). He won World Series as a player with Baltimore (1966, 1970) and as a manager with the New York Mets (1986). ... The Diamondbacks are the only National League team with three players with 35 or more doubles: RF Gerardo Parra (43), Paul Goldschmidt (35) and IF/OF Martin Prado (36). ... LHP Gio Gonzalez will start the final game of the season for the Nationals on Sunday, Johnson said. Gonzalez is 4 2/3 innings and eight strikeouts from 200 in each category. ... Nationals 1B Adam LaRoche (strained biceps) will not play Sunday, Johnson said. Chad Tracy, who spent the first six years of his major league career with Arizona, started at first base Saturday for the Nationals.
