Now they're hoping their pitching can get back on track at Chase Field.
After hitting two more homers in Monday's series opener, Baltimore (65-53) has averaged 6.2 runs and hit .281 with nine home runs while going 4-2 on its eight-game road trip.
Davis belted his major league-leading 43rd home run to tie the game in the eighth inning Monday, his sixth over his last 12 games. He's also batting .421 with seven homers and 13 RBIs in 15 interleague games.
Adam Eaton , however, provided the Diamondbacks (60-57) with a walkoff homer - his first home run of the season - for a 7-6 victory that snapped their two-game skid. Eaton has gone 7 for 18 (.389) in his last four games."We could have got discouraged, we let some opportunities go, but battled back against a pretty good team," Diamondbacks manager Kirk Gibson said after his team twice blew one-run leads in the final two innings.
While the Orioles rank near the bottom of the majors with a 4.29 ERA, they had a 2.20 ERA in the first five games of the trip before getting tagged for three homers by the Diamondbacks.
Showalter will give the ball to Gonzalez (8-5, 3.91 ERA) in hopes he can regain the form he had while going 6-1 with a 2.35 ERA over a recent eight-start stretch.
Since then, the right-hander has struggled with an 0-2 record and 8.16 ERA in his last three starts. Gonzalez pitched slightly better Wednesday, allowing three runs - all in the sixth - and striking out eight over six innings before the Orioles rallied late for a 10-3 win at San Diego.
"You saw what happened in the sixth inning when I started getting behind guys," he told the Orioles' official website. "It's tough no matter where you go and what team you play against. You fall behind and you're going to be in trouble."
Gonzalez has not gone four starts without a win since a five-outing stretch from April 28-May 31.
He'll try to cool off Arizona infielder Aaron Hill , who has homered in a career-best three straight games and has five consecutive multihit games. Hill is 11 for 23 with nine RBIs over a six-game hitting streak.
The Diamondbacks continue to play well in interleague contests at home, winning 10 of 11 while averaging 7.5 runs and batting .328 with 21 home runs.
They also haven't had trouble scoring lately with Randall Delgado (4-3, 3.48) on the mound.
Arizona has won Delgado's last five starts - with the right-hander going 3-0 with a 3.13 ERA in that span - and provided him 24 runs of support in his last three. Delgado settled down after giving up three first-inning runs Wednesday, yielding four runs over five frames before Arizona rallied late for a 9-8 victory over Tampa Bay.
Although he's 1-5 with a 6.48 ERA in seven career interleague starts, Delgado pitched well for the Atlanta Braves in his only start against the Orioles. He limited them to two runs and three hits over eight innings in a 2-0 defeat on June 17, 2012.
Adam Jones went 2 for 3 in that contest and was batting .472 on a nine-game hitting streak before going 0 for 4 Monday.

PHOENIX (AP) -- Paul Goldschmidt had a prime view for the series-opening heroics, watching from the on-deck circle as Adam Eaton splashed a walk-off homer into Chase Field's pool.
He took center stage in the encore.
Goldschmidt hit the first pitch of the 11th inning for a game-ending home run after leading off the ninth with a tying homer, helping the Arizona Diamondbacks beat Baltimore 4-3 on Tuesday night for their second straight walk-off victory over the Orioles.
"I had a good viewing point yesterday to see Eaton, but it's fun either way," Goldschmidt said after his third career walk-off homer.
Goldschmidt was due up second in the ninth inning of a back-and-forth, 7-6 win over Baltimore in the opener Monday night and was one of the first to congratulate Eaton as he crossed the plate.
Goldschmidt one-upped his teammate with two dramatic homers to give Arizona its 25th win in its last at-bat.
The first came in the ninth, when he led off with a drive against Jim Johnson , the major leagues' saves leader.
Goldschmidt's next at-bat came in the 11th, and he wasted no time, lifting the first pitch by T.J. McFarland (1-1) just over the wall in right for his 29th homer and second walk-off of the homestand.
It was Arizona's ninth walk-off and 34th comeback victory.
"Goldy, at the end of a game, it's pretty special what he can do," Diamondbacks manager Kirk Gibson said. "He's a good guy to have on your side."
Heath Bell (3-1) worked a perfect 11th inning, and Gerardo Parra hit his career high-tying eighth homer for Arizona.
Baltimore starter Miguel Gonzalez pitched seven effective innings, and Chris Davis homered for the second straight game to push his major league-leading total to 44.
J.J. Hardy also homered for the Orioles, but their bullpen failed for the second straight night.
"They (the losses) were tough, but you know, we move on," Orioles manager Buck Showalter said.
Gonzalez retired the first 11 batters he faced and had the Diamondbacks off-balance by mixing his low-90s fastball and big curveball.
Gonzalez blew a 3-0 lead in his last start and got into trouble again, this time in the seventh inning.
Aaron Hill got it going with a one-out triple, then scored on Martin Prado 's groundout. Parra followed with a solo homer - his first since June 22 - to pull the Diamondbacks within 3-2.
Gonzalez allowed two runs and five hits.
Francisco Rodriguez did his part with a perfect eighth, but Johnson blew his AL-leading eighth save when Goldschmidt lined a 3-1 pitch over the wall in left-center. It was Goldschmidt's fifth homer in the ninth inning, most in the majors.
Goldschmidt ended it in dramatic fashion, squeezing a drive just over the wall for his fourth career game-ending hit before being mobbed by teammates at the plate. Goldschmidt hit a walk-off homer against the Mets on Friday.
"Looking at what the guys have been putting into the game and the way the game unfolded, it was heartbreaking, but we have to forget about it," Johnson said.
Arizona starter Randall Delgado was sharp for the most part, his only problem was giving up the long ball.
Davis hit the first one, a two-run shot in the fourth inning. Hardy led off the fifth with his 22nd homer to extend his hitting streak to 10 games and put the Orioles up 3-0.
Delgado was good after that, though, allowing three runs and five hits before being lifted for a pinch hitter in the seventh inning.
"Delgado gave up those runs early, we were behind, there was no momentum," Goldschmidt said. "For him to keep putting up zeroes and the bullpen pitching scoreless innings, it gives the offense a chance to come back."
And they did behind Goldschmidt, who was greeted with a chant of MVP! before being mobbed after his latest heroics.
Notes: Davis leads the majors with 43 extra-base hits on the road. ... Arizona has played 16 extra-inning games this season, tied for second-most (2003) in team history. ... Arizona LHP Patrick Corbin , an NL All-Star, is 0-2 with a 2.70 ERA in his last three starts. He will start Wednesday's series finale. ... RHP Chris Tillman , who will start Wednesday against Arizona, is 7-1 with a 2.97 ERA in 10 road starts this season.
