Giants beat Nationals to end five-game skid

SAN FRANCISCO (AP) — Pitcher Todd Wellemeyer singled and scored the go-ahead run to snap San Francisco's 24-inning scoreless drought, Freddy Sanchez hit a two-run double, and the Giants ended a season-high five-game losing streak with a 4-2 win over the Washington Nationals on Tuesday night.

Wellemeyer (3-4) allowed four hits and two runs in six innings to improve to 3-0 lifetime against the Nationals, and sparked the Giants' four-run fifth inning with a two-out single. Pablo Sandoval added an RBI double and Edgar Renteria singled in a run as San Francisco ended an 0-for-25 stretch with runners in scoring position that inning.

The Giants tagged former San Francisco pitcher Livan Hernandez (4-3) for a season-high seven hits and season-high matching four runs in five innings.

Heavy rain threatened to wash out the game and kept the teams from taking pregame batting practice on the field, but it cleared up before game time. A strong rain began again in the top of the seventh, stopped and then briefly started again in the bottom half.

San Francisco opted not to skip Wellemeyer's turn in the rotation after Monday's off day, meaning two-time NL Cy Young Award winner Tim Lincecum will pitch Wednesday night on one extra day's rest.

Wellemeyer allowed three straight singles to start the seventh, including Josh Willingham's RBI base hit, and manager Bruce Bochy turned to reliever Sergio Romo. Ian Desmond hit a sacrifice fly two batters later.

Brian Wilson pitched the ninth for his 11th save in 12 opportunities.

The Nationals had a tough time getting here. After completing a stretch of 20 games in 20 days, the team had planned to spend its off day Monday in the Bay Area. But the Nationals spent five hours on the tarmac Sunday night before getting sent home. Washington finally arrived in San Francisco on Monday to kick off a 10-game trip out West, but not before the waiting another two hours in the plane before takeoff and an hour during a refueling stop in Kansas City.

The Giants won for the 12th time in the last 14 meetings in the series dating to the start of the 2008 season. They needed this one. San Francisco scored only one run getting swept in three games at Oakland over the weekend.

Bochy switched things up for the second straight game.

Regular first baseman Aubrey Huff started in left field — his first time there since Oct. 1, 2006, with Houston — and the first ball of the game came his way. Huff caught Nyjer Morgan's liner.

Sandoval moved from third base to first and Juan Uribe started at third. Aaron Rowand batted eighth and Bengie Molina seventh.

Nats right fielder Roger Bernadina went down briefly in the second after Wellemeyer hit him with a pitch on the outside of his right knee. Bernadina was checked on by trainers, then jogged it off and took first base. He was picked off moments later.

He won't pitch for a few days, but planned to play some light catch Wednesday. ... The Nationals released reliever Brian Bruney and called up C Carlos Maldonado from Triple-A Syracuse. Bruney was designated for assignment May 17. ...
