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.
The Diamondbacks are 3-0 after the All-Star break for the second time in franchise history. The other was in 2002.
The game was scoreless through five innings, then Rizzo lashed the first pitch he saw in the sixth into the seats in the right corner, moving into a tie for the NL homer lead with Miami's Giancarlo Stanton. Rizzo homered twice in the series opener.
Arizona scored twice in the sixth, the first on consecutive doubles by Ender Inciarte and Peralta. Peralta scored from third when Rizzo caught Aaron Hill's high pop foul as he fell over the bar protecting the camera well near the Cubs dugout.
In hindsight, Rizzo might have been better off just letting the ball drop foul.
But, he said, ''I don't think there is any Cubs fan that wanted me to miss it or any Diamondbacks fan that wanted me to catch it.''
The Diamondbacks won a challenge in the seventh when Mark Trumbo was called out stealing second. After a review, the call was reversed. Trumbo scored when Peralta singled.
Ryan Sweeney made two big catches in center for the Cubs. The second was the most spectacular, when he ran deep toward the wall to barely flag down Paul Goldschmidt's deep fly.
