He chose instead to focus on the resiliency of his team, which shook off a couple of late lost leads and ended up on top.
"A win is a win, and this was a total team effort," Hill said. "We keep battling back, and this is fun. It's great to see this team rewarded for good things."
Prado sent the game to extra innings when he backhanded a liner by Jedd Gyorko down the third-base line with the bases loaded in the ninth.
"In that situation, you have to guard the line," Prado said. "You have to be careful and make sure you're in a position to make a play."
Prado, who reached base four times with a single, a double and two walks, has hit in 13 of his past 14 games, with 21 RBIs. He has a career-high 71 RBIs this season.
Eaton opened the 10th with a single to center, and Paul Goldschmidt singled to left. With Hill at-bat and runners on second and third, the Padres employed a five-man infield.
The Diamondbacks played their 20th extra-inning game this season, second only to the 21 they had in 1999. Arizona is 15-5 in this season's long contests.
San Diego dropped to 7-6 in extra innings.
"No doubt, this was a game which had direction," Padres manager Bud Black said. "This one was hard to describe. The game is played by human beings, and you never know how the game will play out. This game was a testament to that."
The Diamondbacks entered the eighth with a three-run lead and were up by two runs in the ninth but couldn't hold on.
Arizona trailed 3-0 in the first inning, but Parra tied it in the second with a three-run homer. He drove in two more with a bases-loaded single in the fifth when the Diamondbacks grabbed a 6-3 lead.
Both hits came against Padres starter Ian Kennedy, who made his first start against his former team. Kennedy lasted only 4 1/3 innings, allowing six runs, six hits and a season-high five walks. He also hit a batter.
It was the most runs given up by Kennedy since yielding 10 on June 6 against St. Louis while pitching for Arizona.
Diamondbacks starter David Holmberg also struggled in his major league debut. The first five hitters reached base, and three scored.
Kennedy needed only 11 pitches to get through the first.
The usually reliable Diamondbacks bullpen couldn't hold leads in the eighth or ninth. Will Harris and Ziegler were both charged with blown saves.
