SAN DIEGO – Jay Bruce joined the Phillies on Monday hoping to provide depth to a severely depleted outfield. Less than 24 hours later, he found himself a critical piece to a lineup that must play the remainder of the season without Andrew McCutchen.

He answered the call Tuesday.

Bruce went 3-for-4 with one double, two home runs and six RBIs in a 9-6 victory over the Padres at Petco Park. He hit a two-run home run to left field in the fourth inning against Chris Paddack to hand the Phillies a one-run lead. He hit a grand slam to right field in the fifth against Brad Wieck to turn a two-run lead into a six-run lead, snapping the Phillies’ season-high losing streak at five games and giving them a chance to win the series with a victory in Wednesday’s finale.

“First of all, the news was devastating about someone I have so much respect for as a player,” Bruce said. “I’ve gotten to know him over the years and we came up playing together. I know how much he meant to this team and I’m definitely not coming to try to replace Andrew McCutchen. What he does and has done in his career speaks for itself. He’s a good player. I just wish a speedy recovery for him and hope he’s ready as soon as possible.

“My mindset doesn’t change. I just want to play and play well and help this team win a championship.”

Bruce is the first Phillies player with two home runs and six RBIs in a game since Ryan Howard on April 29, 2011, against the Mets at Citizens Bank Park. He is the first Phillies player to accomplish the feat on the road since Jim Thome on June 8, 2004, against the White Sox in Chicago.

"Bruce was seeing the ball all night,” Paddack said. “I gotta tip my cap to that guy. I made a few mistakes up in the zone. I tried to blow it by him, second at-bat. To a guy like that, you've just got to tip your cap."

Bruce flied out to the warning track in left field in the seventh inning, almost becoming the first Phillies player to hit three home runs in a game since Jayson Werth on May 16, 2008, when he had three homers and eight RBIs against the Blue Jays at Citizens Bank Park.

Scott Kingery also doubled and homered for the Phillies, making the night a double bonus. The Phillies are counting on Bruce and Kingery to boost an offense that has been struggling recently and must make up for the lost production from McCutchen, who tore the ACL in his left knee on Monday and will miss the remainder of the season.

Bruce and rookie Adam Haseley will get the majority of playing time in left and center field, respectively. Kingery will see more regular playing time at third base. If they perform as hoped, the Phillies can focus their efforts to upgrade their roster in other ways before July 31.

Kingery’s homer followed Bruce’s homer in the fourth. The ball left his bat at 107.5 mph and traveled a projected 408 feet, making it the longest home run of his career, according to Statcast.

The ball landed in the second deck in left field.

“I told Rhys [Hoskins], that might have been one of the best feeling balls I’ve ever hit in my entire life,” Kingery said. “I told him that I don’t know if I’ve ever hit a ball past the fourth row in my life.”

Phillies right-hander Jerad Eickhoff allowed four hits, three runs and one home run in six innings. He struck out five. He had been struggling recently, so this was a good win for him, too.

“In a lot of ways, we played with Andrew out there,” Phillies manager Gabe Kapler said. “We kind of won one for him. When I'm thinking about the injury, one of the cool things that we have going on here is we have reinforcements coming. We don't have to wait until the Trade Deadline to make any sort of acquisitions to make our club better. We have Roman [Quinn] who is not that far away. Tommy [Hunter] is on his way. Adam Morgan is on his way. All of these guys are going to make us slowly stronger as a unit.”
