PHOENIX (AP) - Chicago Cubs first baseman Anthony Rizzo made a remarkable catch, tumbling into the photo well to snag a foul ball.

And it might have cost the Cubs the game.

Josh Collmenter threw seven sharp innings, David Peralta drove in a pair of runs and the Diamondbacks beat the Cubs 3-2 on Sunday to complete a three-game sweep.

The go-ahead run was waved home automatically in the sixth inning after Rizzo came down with the ball in his glove for the out. By rule, if a defensive player takes the ball out of play, each runner is awarded a base.

The only run Collmenter allowed was Rizzo’s 23rd home run of the season, matching his total for all of last year.

Collmenter (8-5) gave up just three other hits.

“I was able to command the fastball both sides of the plate,” he said. “With a lot of lefties in the lineup I was able to pitch in really well, got a lot of popups and ground balls and the defense made some great plays.”

David Peralta had a run-scoring double to tie it, then came home from third on Rizzo’s camera well plunge.

Rizzo said it was “just instinct” that he lunged for the ball.

“I didn’t think I would go in (the camera well),” he said. “But it was a little farther then I thought.”

The Diamondbacks earned their second sweep of the season, first at home.

The Cubs have lost 11 of 13 since Jeff Samardzija was traded to Oakland on July 5.

Jake Arrieta (5-2), who had a stomach virus the past few days, allowed three runs and four hits in 6 2-3 innings for the Cubs.

It was a tough series, tough game today,” he said. “The challenge really for me was what I had to deal with the last few days, trying to hold fluids down. My body was weak not being able to eat any solid food.

Addison Reed pitched a perfect ninth for his 23rd save in 28 tries.
