PHOENIX -- The Arizona Diamondbacks feasted on the Philadelphia Phillies' pitching for a second straight night. On Tuesday night they did so in record-setting fashion.
David Peralta hit a grand slam in an 11-run second inning and tied a career high with five RBIs, leading the Diamondbacks to a 13-1 victory.
The 11 runs -- all off starter David Buchanan -- were the second-most scored in an inning in Diamondbacks' history. Peralta and Aaron Hill hit home runs and Jeremy Hellickson became the second pitcher in club history to collect two hits in one inning.
"As soon as I hit the ball I knew it was gone," Peralta said. "It feels good when you do something to help the team win. We are doing really well right now."
The Diamondbacks (56-56) are .500 for the first time since July 8, when they were 42-42.
Hellickson (8-8) allowed an unearned run and seven hits, striking out six in eight innings and improving to 6-1 in his last seven home starts.
"I can't tell you the last time I went eight innings. The hits were nice as well," Hellickson said. "I will sit in the dugout as long as I need to. Let the guys score as many runs as they want."
Arizona had a club-record 10 hits in the big inning, and five extra-base hits, which tied the team record. The 11 runs allowed by the Phillies were the most they gave up since allowing 12 in an inning on May 31, 1975.
Buchanan became the first Phillies pitcher to allow 11 or more earned runs in an inning since Al Jurisch, who surrendered 14 against the New York Giants on June 28, 1947.
Buchanan (2-7) was done after 1 2-3 innings. He entered the game with an ERA of 7.23 and it went up to 9.00.
"Once the game started the ball was elevated, and that's when you get hurt," Buchanan said. "Try to keep pitching, try to get guys out, but the ball was elevated and I had to get the ball down."
The Diamondbacks, who won for the fourth time in five games, had four players with two hits in the same inning for the first time in franchise history: Yasmany Tomas, Hill, Chris Owings and Hellickson.
Peralta's fifth RBI came in the fifth inning, a run-scoring single, and Jarrod Saltalamacchia hit a solo home run in the sixth.
The Phillies took a 1-0 lead in the first on a single by Ryan Howard and a fielding error that allowed pinch-runner Andres Blanco to score from first base.
The Diamondbacks have outscored the Phillies 26-4 in the past two games after a 13-3 drubbing Monday night. This is the second time the Diamondbacks have ever scored 13 or more runs in consecutive games, the last time Sept. 26-27, 2001, when they scored 15 in one game and 13 in the next against Milwaukee.
"We came out and really swung the bats. Very impressive," Diamondbacks manager Chip Hale said. "A good game plan, and they executed and kept it going. Even the pitcher. It was good to see."
UTLEY PLAYS AMID TRADE SPECULATION
Longtime Phillies INF Chase Utley cleared waivers before Tuesday's game, making him trade-eligible. Several published reports named the San Francisco Giants, Chicago Cubs and Los Angeles Dodgers among the teams interested in acquiring the 11-year veteran, who started at second base against Arizona.
Utley, who was 2 for 4, can block any trade because of his tenure in the majors and with the Phillies. He was activated from the 15-day DL last Friday after being out more than a month with right ankle inflammation. He is hitting .196 in 70 games this season.
Phillies manager Pete Mackanin said he plans to rest Utley for a day game Wednesday, and after Tuesday's game said there will probably be a discussion about a move on Wednesday.
Home plate umpire Doug Eddings issued a warning to both dugouts after Phillies reliever Hector Neris hit the Diamondbacks' Paul Goldschmidt with a pitch in the third inning. That was after Hellickson hit the Phillies' Maikel Franco in the left wrist and forced him out of the game in the first inning. "We'll see if it will feel better (Wednesday)," Franco said. "When the ball hit me I thought it was broken."
PHILLIES: Franco showed some swelling in his wrist but X-rays were negative and he was diagnosed with a contusion. "It wasn't broken, so that was good news," Mackanin said. "It looked bad. It sounded bad. I thought for sure it was broken but fortunately it wasn't." . OF Domonic Brown was scratched from the lineup due to illness, and was replaced in right field by Jeff Francoeur.
DIAMONDBACKS: Tomas left the game after the second inning for precautionary reasons with tightness in his left quadriceps, Hale said. Tomas was replaced in right field by Ender Inciarte and Hale said he's not certain if Tomas will be able to play on Wednesday. ... C Welington Castillo, who is hitting.366 with eight home runs and 14 RBIs in his last 12 games, was not in Tuesday's lineup. He took a bat to his helmet on a backswing while catching in the sixth inning Monday but stayed in the game a little while longer and said he was fine afterward. Hale planned to give Castillo a day off on Tuesday or Wednesday anyway, he said.
PHILLIES: RHP Aaron Nola, 22, faces the Diamondbacks for the first time in his career. Nola, called up in July from Triple-A, has not lost since his first start on July 21. He's 2-1 with a 3.65 ERA in four starts.
DIAMONDBACKS: RHP Chase Anderson makes his second start since being reinstated from the 15-day DL on Aug. 7. Anderson (5-4, 4.10 ERA) got a no-decision in May at Philadelphia despite giving up a run and three hits in 5 1-3 innings.
