PHOENIX -- The D-backs got what they wanted: They're headed back to Milwaukee.
Their backs against the wall, the Arizona Diamondbacks came out swinging Wednesday night as they slammed the Brewers, 10-6, in Game 4 of the National League Division Series.
The series now heads back to Milwaukee for a winner-take-all Game 5 on Friday night at Miller Park.
"We got our confidence here at home in front of our home fans and we just need to take that confidence back to Milwaukee," right fielder Justin Upton said.
The two teams each won both games played on their home fields, and if the D-backs hope to advance to the NL Championship Series, they will have to beat Brewers ace Yovani Gallardo at Miller Park on Friday, something they were unable to do in Game 1.
"I think we have a little bit more idea what to expect," shortstop Willie Bloomquist said about the playoff atmosphere at Miller Park. "The game time is going to be the same time as the last game there so we know what to expect, what the atmosphere will be like as far as shadows are concerned. Obviously their fans there are great, so they'll probably be a little bit louder this go-around, too, but we'll be up for it. This is what it's all about. It's going to be a lot of fun."
It looked initially like the D-backs might be in trouble Wednesday when the Brewers grabbed a 1-0 lead on Ryan Braun's RBI double in the first off left-hander Joe Saunders, who did not appear to have his best stuff.
The lead did not last long, though, as Brewers starter Randy Wolf gave it right back and then some in the bottom of the first.
The big blow of the inning was a two-out grand slam by third baseman Ryan Roberts.
"Just try to stay relaxed, try to breathe, try to not do too much," Roberts said of his approach. "In that situation it's easy to get too big and I've done it many a time, so just try to stay relaxed and try not to do too much, stick to an approach. I had the approach of sitting in and luckily didn't miss it."
It was the fourth straight home game in which the D-backs recorded a grand slam. Arizona got grand slams from Roberts and Cole Gillespie to end the regular season and then got one from Goldschmidt in Game 3 of the NLDS.
According to the Elias Sports Bureau, the D-backs joined the 1977 Dodgers as the only teams to hit grand slams in back-to-back games in the postseason, and they became the fifth team to hit two grand slams in a single playoff series.
Chris Young followed with a homer of his own, the first of two on the night for him, and the D-backs led 5-1.
"It's awesome when you give up one run in the first inning and the team comes out and throws up a five-spot for you," Saunders said. "Its unbelievable, it really is. The confidence we have offensively is off the charts right now and it's fun to watch."
The Brewers began to chip away at the lead with single runs in the second and third innings, but any momentum they may have gotten quickly dissipated in the third when pinch-hitter Collin Cowgill delivered a two-out, two-run single.
"A lot of jitters -- I was a little nervous," Cowgill, a rookie, said of his first postseason at-bat. "But I just tried to get into a good count, get a good pitch to hit, don't do too much."
The decision to pinch-hit Cowgill for Saunders was one of several strategic moves that paid off for D-backs manager Kirk Gibson.
Gibson also decided to switch Roberts and Young in the batting order. He refused to say before the game why he made the move, but said there were some things he saw that made him think it would be beneficial.
"I showed up and saw I was batting seventh," said Young, who hit sixth in Game 3. "Honestly, it didn't matter to me. You don't get selfish at this point in the season, you just try to do your part and stay positive and be ready when your at-bat comes up."
Despite the early lead, the Brewers never seemed out of this one.
They loaded the bases with one out against rookie Jarrod Parker and the fans held their collective breath when Corey Hart then blasted a fly ball to deep left-center. Instead of it being a game-tying grand slam, left fielder Gerardo Parra was able to catch the ball on the warning track, and Milwaukee managed just one run on the sacrifice fly.
Meanwhile, the D-backs continued to score as they added a run in the sixth on a homer from Aaron Hill and two more in the seventh on Young's second homer of the evening.
"They're a team that doesn't go away," Bloomquist said. "They obviously have a good offense and that's why it's important to keep adding on runs when you can, and that's what we did today so that was obviously huge for us."
Carlos Gomez pulled the Brewers within four with a two-run homer in the eighth off David Hernandez, but Milwaukee would get no closer.
Gibson was criticized by some for his decision to start Saunders rather than bring Game 1 starter Ian Kennedy back on short rest. Now Gibson has Kennedy, his ace, well rested for a decisive Game 5.
"To keep things in perspective, we haven't accomplished anything yet," Gibson said. "We didn't come here to win two games and not win the series. We're going back to a very hostile environment. We know what it's like, we've been there the first two games and we've got our work cut out for us."
Maybe so, but they're still alive, something that certainly wasn't assured after dropping the first two games of this series. Under the current NLDS format, which began in 1995, no NL team has ever rebounded from an 0-2 deficit to win the series.
"I know probably a lot of people are [surprised], but we're certainly not," Bloomquist said. "We've crawled out of many holes this year, so we know what we have to do and what the task is. So we're going to go into Milwaukee and put our best foot forward and see what happens."
