“It was nice to see," Casali said. "We’ve been waiting a while to get Webby back.”
Wilmer Flores also homered as the Giants debuted their all-white City Connect home uniforms with images of the Golden Gate Bridge along each sleeve.
“It was kind of fun to have a new look, it was kind of cool," manager Gabe Kapler said. "The energy in the ballpark was fantastic and really liked the choice of music throughout the game. There was a lot of Bay Area hip hop that fit perfectly with the jerseys and the vibe and the energy in the building.”
Adding to the festive night, there were even mid-game fireworks outside in McCovey Cove that Kapler called “an incredible touch.”
Webb allowed one hit over three innings and struck out four in his first outing since May 29 after missing time with a strained right shoulder. He struck out four. The Giants hoped to get him through three innings.

Giants reliever José Álvarez, who came in for Webb in the fourth, was ejected by plate umpire David Rackley for arguing after being removed from the game.
Washington’s Tres Barrera hit a two-run triple in the fourth for his first career extra-base hit and RBI.
Slick-fielding Giants shortstop Brandon Crawford made a lunging stop on Barrera's grounder in the sixth and used his glove to make a flip to second baseman Donovan Solano, who completed a double play.
“That was as good a web gem as I’ve seen,” Casali said.
Jarlin García (1-0) pitched the fifth for the win. Jake McGee, the seventh Giants reliever of the night, escaped trouble in the ninth to finish for his 18th save.
Starlin Castro had two hits and extended his hitting streak to 12 games for Washington.
Nationals: RHP Stephen Strasburg, sidelined since June 2 by a strained neck, pitched a simulated game Thursday and Martinez said: “It went well. We’ll see what’s next for him.

OF Andrew Stevenson (strained right oblique) homered in the first inning of a rehab game for Triple-A Rochester before the game was later suspended by rain.
Giants: C Posey was placed on the 10-day injured list (retroactive to July 6) with an injured left thumb. ... 1B Brandon Belt took about 50 swings in the batting cage and fielded groundballs for the first time as he recovers from an inflamed right knee, which is protected by a brace as he does his workouts. He has twice had surgery on that knee. ... LaMonte Wade Jr. was a late scratch at first base and Ruf replaced him. Wade tested his tender hand by hitting with increased intensity and the Giants opted to play it safe with him.
LHP Jon Lester (2-3, 5.34 ERA) pitches Saturday for the Nationals looking to win consecutive decisions for the first time his year. RHP Anthony DeSclafani (9-3, 2.84) seeks double-digit wins for the first time in his career.
