St. Louis, which sits in first place in the National League Central, has beat up on Arizona over the first two games of the series, outscoring the D-backs, 15-7, while its starters have tossed 12 scoreless innings.
However, St. Louis has yet to sweep a team this season, and will to turn to Kyle Lohse on Wednesday in an attempt to do so.
Lohse is coming off his first loss of the season, allowing five runs (three earned) to the Astros after surrendering just six runs combined in his previous five outings. The right-hander will take a 4-1 record, 2.11 ERA and 0.94 WHIP into Wednesday's matchup against the undefeated Wade Miley.
"It was a grind," Lohse said following his last start. "I felt like I missed a couple spots early and they made me work a little bit more than I have had to in recent starts. I didn't think I had too bad of control. I was up in the zone. I felt like I was right around the zone all night. A couple calls could have gone either way. I did get a little frustrated there."
Miley, 3-0 with a 2.33 ERA and 0.96 WHIP, has been a pleasant surprise for the D-backs.
The 25-year-old allowed a season-high four runs against the Mets in a no-decision his last outing and has made just 10 career starts since making his Major League debut last year.
Miley, who will be making his fourth start in place of the injured Daniel Hudson, will look to help the D-backs snap a four-game losing streak and help them inch closer to the Dodgers, whom Arizona trails by 5 1/2 games in the NL West.
"Everybody gets frustrated," D-backs manager Kirk Gibson said. "We haven't played well, and nobody is happy with that. We've lost some games recently where we've made some mistakes and it has cost us dearly. Everybody is trying hard. But you can't start feeling sorry for yourself because we haven't been as successful as we want to be. The only way to get out of it is to power through it."
Cardinals: Beltran chasing history
Carlos Beltran needs two stolen bases to become the eighth player in Major League history with at least 300 steals and 300 homers. Even more impressive is the fact that Beltran would become the first switch-hitter to accomplish the feat.
The former All-Star has been a major offseason acquisition for St. Louis and has helped the club in its back-to-back wins over Arizona. Beltran hit two homers and drove in six runs in Tuesday's win, a night after hitting a solo homer.
Beltran increased his team-leading home run total to 10 and is batting .288 with a .985 OPS on the season.
Tyler Greene is expected to get the start at second base in the series finale because the Cardinals will be facing a lefty in Miley.
It will mark the first time this year that St. Louis will face two left-handed starters in the same series and will also mark the third lefty the Cardinals have faced in their past four games.
Greene had a three-hit, two-homer game Sunday and one hit in his start Monday. He has been working on making some adjustments, with the help of hitting coach Mark McGwire and assistant hitting coach John Mabry. The adjustments have been both mechanical and mental.
"I know he's been proactive on both," manager Mike Matheny said. "They kind of go hand-in-hand with what Mark and John have been working with him on in the cage. With him, it's as much mindset as it is mechanical. To get positive results always reinforces that he's working on the right things."
D-backs: Upton struggling
The D-backs haven't been getting much production from the No. 3 spot in their lineup, which belongs to All-Star Justin Upton.
Upton is batting just .235 with three homers and a .686 OPS, but his skipper isn't concerned with his star outfielder's slow start.
"Justin is working hard, he knows what he's doing, he's trying to stop it," Gibson said. "I'm not sure what people think, but I know they get frustrated with it. They key is to not get frustrated with it. To keep your composure and power through it."
Center fielder Chris Young, who hasn't played since April 17 because of a shoulder contusion, is making strides toward returning to action.
"He looked much better today, he hit a lot," Gibson said. "He's a little bit out of shape -- you're away from it [baseball]. He wants to play. He might play Thursday [in extended spring training]. We'll see how he feels."
Before landing on the disabled list, Young was off to a hot start, batting .410 with five homers and 13 RBIs over 11 games.
