WASHINGTON — Jayson Werth homered and doubled to lead the Washington Nationals to a 7-3 victory Tuesday night in his first appearance against Philadelphia since leaving the Phillies as a free agent this winter.

Werth doubled to lead off the fourth inning and later scored, starting a three-run inning that gave the Nationals the lead for good. His solo home run in the fifth gave Washington a 5-1 lead.

Werth signed a $126 million, seven-year contract with the Nationals this offseason. Phillies fans made up a large percentage of the sparse crowd at Nationals Park and booed him each time he came to bat or fielded a fly ball in right field.

Livan Hernandez (1-1) allowed one run on seven hits, struck out six and didn’t walk a batter in 62/3 innings.

Sean Burnett got the final five outs for his third save.

BRAVES 5, MARLINS 0: Tommy Hanson pitched four-hit ball over seven innings for his first win, Jason Heyward and Brian McCann homered, and Chipper Jones drove in two runs to lead Atlanta at home.

Hanson (1-2) finally got a few runs to work with and the Braves turned in several nifty defensive plays, two of them diving stops by shortstop Alex Gonzalez.

The Braves have struggled offensively over their first 10 games, scoring three runs or fewer seven times, including both of Hanson’s starts. This time that wasn’t a problem. Heyward homered in the fourth, McCann in the fifth.

ASTROS 11, CUBS 2: Brett Myers kept up his dominance against Chicago and Angel Sanchez tied a career high with four hits as Houston won at home.

Myers (1-0) allowed eight hits and one run in seven innings to improve his career record against Chicago to 11-3.

Houston scored three off James Russell (1-1) in the first inning, two more in the second and built a 7-0 lead in the fourth.
