SAN DIEGO _ Kevin Pillar's eyes did not deceive him.
If it looked like San Diego Padres reliever Luis Perdomo was operating in slow motion through his delivery, Pillar didn't have to wait long for confirmation.
Perdomo tip-toed through his windup, lobbed a ball to the plate and watched as his pitch clanked off the top of Pillar's left cleat.
If the plunking caused any pain, Perdomo and the Padres were the only ones who felt it. The bizarre hit-by-pitch ignited a four-run sixth-inning San Francisco Giants rally that gave the club a lead it would never relinquish en route to a 7-5 victory and the team's first three-game sweep of the season.
The Giants (39-47) had gone more than a full calendar year since securing a three-game sweep, but with 30 runs in three days at Petco Park, Bruce Bochy's squad finished off a stretch of 20 games in 20 days with an 11-9 record.
San Francisco has now scored at least seven runs in four consecutive games for the first time since Aug. 16-19, 2006, when they put up a combined 29 runs in games started by Padres pitchers Chan Ho Park and Jake Peavy and Dodgers righties Brad Penny and Greg Maddux.
Perdomo's streak of 14 1/3 innings without surrendering an earned run came to an abrupt ending after the hit by pitch. While the reliever appeared confused as to whether Pillar was granted time by home plate umpire, a tiny shred of uncertainty was all the Giants needed to pounce on the Padres.
Donovan Solano, Pablo Sandoval, Brandon Belt and Austin Slater followed Pillar's hit by pitch with RBI hits to give the Giants a comfortable three-run advantage.
Solano, Belt and Slater all deposited hard-hit balls into the right center field gap, but Sandoval hit a flyball that should have been a routine play for center fielder Wil Myers. Instead, Myers lost the ball in the lights and Sandoval chugged into second base with his 17th double of the season.
With a 430-foot, two-run blast into the Giants bullpen in the top of the third, Longoria became the first Giants player since Jarrett Parker (Sept. 25-27, 2015) to homer four times in a three-game series. Since 2000, only two other Giants players have hit at least four home runs in a three-game series as Barry Bonds accomplished the feat in four different series while Ellis Burks did it once.
Longoria's home run was the longest he's hit this season according to Statcast as it traveled 18 feet farther than the 412-foot homer he hit off the top of the Western Metal Supply Co. building in Tuesday's victory.
Two pitches later, left fielder Alex Dickerson crushed a 422-foot solo shot into the right field bleachers to give the Giants a 3-2 lead.
Longoria and Dickerson became the first Giants teammates to hit back-to-back home runs since Alen Hanson and Chris Shaw homered in consecutive plate appearances on Sept. 3, 2018 at Coors Field in Denver.
Dickerson came up with the Giants trailing by a run and another chance to do damage in the fifth inning, but the Poway, Calif., native and former Padres outfielder bounced into an inning-ending 4-6-3 double play with the bases loaded. A base hit would have taken starter Shaun Anderson off the hook for a loss, but Anderson had to wait until Solano delivered a game-tying RBI double in the four-run sixth for that to happen.
Solano's double extended his hit streak to 10 games as he notched his first 10-game hit streak since Sept. 19-30, 2012, when he was with the Miami Marlins. The six-plus year stretch in between 10-game hit streaks is the second-longest for an active player in the majors as Texas Rangers catcher Jeff Mathis went slightly more than seven years between 10-game hit streaks.
Another offensive outburst and a strong night from the Giants' bullpen helped the club overcome a shaky outing from Anderson, who gave up four innings in a four-inning start that marked the shortest of his brief career.
