DENVER -- The Colorado Rockies will try for a split of their four-game series with Arizona and the Diamondbacks will attempt to complete a 10-game road trip with an 8-2 record when the teams meet Sunday.

Diamondbacks first baseman Paul Goldschmidt has a chance to tie a notable record. He has reached base safely in 47 straight games against the Rockies. That is a franchise record against any opponent and one game shy of the longest on-base streak against the Rockies.

Mike Piazza reached base safely in 48 consecutive games against Colorado from July 1, 1995 to Sept. 13, 1999.

In the past 18 games, Goldschmidt is hitting .408 (29-for-71) with six doubles, four homers, 14 RBIs and 11 walks. He has reached base via a hit or a walk in 17 of his past 19 road games, going 24-for-71 (.338) during that span with four doubles, two homers, 11 RBIs and 17 walks.

That surge has left Goldschmidt with an overall average of .300, 14 doubles, 14 homers, 47 RBIs, 43 runs, 63 walks, a .436 on-base percentage and .517 slugging percentage.

"I think he's hitting the ball well, and he's putting into play the balls that are in the zone for him," Diamondbacks manager Chip Hale said. "Early in the year, the pitches that he could handle were being fouled back. Now they are going out into fair territory for hits. So Paul is getting better pitches, putting them into play, and if they are not coming into the zone, he is taking walks."

While Goldschmidt is a middle-of-the-order force and slugging his way toward another robust season, Rockies second baseman DJ LeMahieu, who typically bats second, has made more subtle offensive strides.

LeMahieu hit a three-run homer in the eighth inning Saturday that completed the scoring in Colorado's 11-6 win and gave closer-for-the-day Gonzalez Germen an ample cushion in the ninth.

LeMahieu, who went 2-for-4, is hitting .328 -- the highest his average has been since April 17 -- with 19 doubles, five triples, five homers, 29 RBIs and 46 runs. He has a .392 on-base percentage and a .500 slugging percentage.

LeMahieu is one homer shy of the career-high six he hit last year when he batted a career-high .301, raising his lifetime average to .284. He has reached base safely in 34 of his past 37 games, and his 29 extra-base hits this season are three shy of his 2015 total.

"He's really evolved into an offensive threat," Rockies manager Walt Weiss said. "I feel like he's using his back side to hit. That allows him to drive the ball. I just think he's growing as a hitter. He understands the timing, rhythm and balance throughout the swing.

"I see the lower half much more involved this year than I did in the past. I always felt a couple years ago his on-base and his slugging (percentages) would increase because of his ability to adapt, his feel for the game, his instints, his baseball IQ."
