Nolan Arenado's latest performance at the plate has the Colorado Rockies on the verge of the franchise's first road sweep against the Philadelphia Phillies.

He'll try to stay locked in while leading his team to a seventh win in eight games Sunday.

Arenado is batting .458 (11 for 24) with four homers and 12 RBIs in his last six games after registering a solo shot and an RBI single in a 5-2 victory Saturday. The Rockies (21-26) finished with 10 hits, giving them double digits in seven of the past 10 games, and they're batting .288 while averaging 6.0 runs in that stretch.

Ben Paulsen homered for the second straight game and is batting .359 since being called up from the minors May 19.

"He came up last year and performed extremely well and he's doing the same this year," manager Walt Weiss told MLB's official website. "He's a good hitter, not just a power hitter. He hits the ball to all fields and drives the ball."

The Phillies have been nowhere near as proficient as Colorado, totaling 11 runs during a season high-tying six consecutive defeats while batting .211. They've gone 0 for 20 with runners in scoring position in the past three while plating a combined three runs.

"We were getting the big hit and we've lacked that in the cold streak," manager Ryne Sandberg said. "We have to keep knocking on the door, and somebody needs to come up with the big hit."

That would seem to give Colorado a prime opportunity for the three-game sweep and Jordan Lyles (2-5, 5.10 ERA) a promising chance to end his woes.

Lyles is 0-4 with a 7.43 ERA in his last five starts and was forced to leave in the fifth inning in last Saturday's 10-8 loss to San Francisco because of a sprained left toe. The right-hander also pitched just one inning against the Los Angeles Angels on May 13 because his pitching hand was bruised by a line drive.

Lyles went through some tests Friday that left Weiss assured that he could perform in this outing.

"We put him through the ringer. He did all right, so we feel pretty good about him making the start," Weiss said.

Lyles is facing the Phillies (19-32) for the second time in three starts. He took a 4-3 loss in Denver on May 18, allowing four runs in six innings, and is 1-1 with a 3.41 ERA in five lifetime starts against Philadelphia.

Lyles is also 4-18 with a 5.49 ERA in the 35 career afternoon games, including 33 starts.

Opposing him is Jerome Williams (3-4, 5.33), who will seek a fourth win in the past five home starts. The right-hander is 3-1 with a 3.45 ERA in five games at Citizens Bank Park this season and 0-3 with a 7.46 ERA in his five away from there.

Williams, however, had a relatively solid outing Tuesday at the New York Mets with just one lackluster inning, allowing three runs, three hits and two walks in the third. He yielded two hits and two walks in his other five innings.

Williams was charged with five runs in five innings in a 7-3 loss at Colorado on May 21. Brandon Barnes went 3 for 3 with a double and Michael McKenry, batting .342 in 15 games against Philadelphia, had a two-run homer and two walks.

The Phillies haven't lost seven in a row since an eight-game skid in July 2013.

Colorado, loser of 21 of 26 in Philadelphia prior to this series, is seeking to win four straight for the first time since its 4-0 start to this season.
