Daulton Varsho continued his assault on his father's former team with a tiebreaking single as the visiting Arizona Diamondbacks scored three times in the seventh inning Saturday afternoon en route to a 7-3 victory over the Chicago Cubs.

The game was delayed 99 minutes in the middle of the ninth inning by lightning and heavy rain. Anthony Rizzo scored the Cubs' final run on a wild pitch following the restart.

Varsho, the son of ex-Cubs outfielder Gary Varsho, homered at Wrigley Field for the second consecutive day and ran his string to three consecutive games with a long ball.

Diamondbacks right-hander Merrill Kelly (7-7) ran his unbeaten string to seven starts with six effective innings, allowing Arizona to draw even in the three-game series after taking an 8-3 loss 24 hours earlier.

Having rallied from a 2-0 deficit earlier, the Diamondbacks took command for good after reliever Andrew Chafin (0-2) walked Pavin Smith and Nick Ahmed to open the seventh.

Varsho followed with his go-ahead single to left, and pinch hitter Asdrubal Cabrera then laced a two-run double to right, giving Arizona a three-run lead and paving the way to a fifth win in the club's past six games.

Cabrera had been activated off the injured list before the game. He missed the previous nine games due to a strained right hamstring.

He remained in the game at third base after his pinch-hitting assignment and added a second double in the ninth. Pinch hitter Andrew Young then beat the rain delay with a two-run homer, his sixth of the season, to complete the Arizona scoring.

Varsho's homer, his fourth of the year, began Arizona's rally in the fifth. The two-out, two-run shot off Cubs starter Alec Mills drew the visitors even at 2-2.

The 25-year-old finished with three RBIs, equaling the career high that he established with a double and a homer in the series opener.

Mills was pulled after five innings, having allowed just the two runs and three hits. He walked two and struck out one.

Chicago built its early lead with single runs in the third and fourth. A double-play grounder by Javier Baez opened the scoring, before Willson Contreras smacked a homer, his 15th of the year, while leading off the fourth to make it 2-0.

Kelly benefitted from the seventh-inning uprising to win his fifth consecutive decision. He was charged with two runs on five hits, with one walk and six strikeouts.

Eduardo Escobar had two hits for the Diamondbacks, while Kris Bryant collected a single and a triple for Chicago.
