Sometimes baseball gives you a chance to redeem yourself, but it’s up to you to make the most of it.

Nick Ahmed did just that during the D-backs’ 4-3 walk-off win over the A’s on Monday night at Chase Field. David Peralta's walk-off single lifted the D-backs above .500 at 12-11 and extended their win streak to five games.

But that was the end of the redemption story. First, came the unimaginable. Ahmed has won the past two National League Gold Glove Awards for shortstops, so what happened in the top of the eighth inning was stunning.

With the D-backs nursing a 3-2 lead and two outs, Matt Olson lifted a pop fly into shallow left field. Ahmed raced back, reached up to catch it and just whiffed it. The ball hit the turf, and the tying run scampered home.

“It’s a ball I’ll catch 100 times out of 100 if I go do it right now,” Ahmed said. “I just missed it. Last step, I kind of felt my head move and didn’t quite see it into my glove.”

That prompted a mound visit. During the stoppage, while his teammates encouraged him, Ahmed was still trying to process what had just occurred.

“I just felt bad in that spot,” Ahmed said. “I felt like I let the team down. I felt like crap. I felt like I let everybody down.”

Ahmed’s teammates, though, didn’t see it that way and let him know it.

For manager Torey Lovullo, that told him everything he wanted to know about his team.

“The best part about it was the way the team rallied around him,” Lovullo said. “I heard some comments that came out of that mound visit that made me think it was a very special group. They picked up one another. In this case, they picked up Nicky, who is usually picking everybody else up defensively.”

The inning ended, and as Ahmed jogged off the field, he knew he had to put the error behind him because the game still hung in the balance. That was still true when Ahmed led off the bottom of the ninth against Joakim Soria.

“I mean, I’m frustrated, making a mistake like that in a big spot,” Ahmed said. “You have to learn how to separate it. If I’m in the box facing a really good pitcher and thinking about an error I just made, I’m already defeated. You have to learn from your mistake quickly, move past it and keep playing the game.”

Ahmed delivered a line-drive double to left field.

“The game affords you a second chance,” Ahmed said. “That’s what’s great about baseball. I’m leading off the ninth inning and get a chance to help us win a game. I just locked it in and had a good plan on Soria and was able to hit a double to help us win a game.”

One out later, Ahmed moved to third on a single and the A’s intentionally walked Starling Marte to get a left-on-left matchup between Peralta and Jake Diekman.

Peralta badly swung through two low sliders from Diekman before making an adjustment only a savvy hitter makes. Just before Diekman started his delivery, Peralta inched up a bit in the box, hoping to be able to hit that low slider before it tailed too far down and away.

That move, combined with the fact that Diekman caught a little more of the plate than he wanted to with the pitch, allowed Peralta to poke a single through the drawn-in infield to score Ahmed with the game-winner and a bit of redemption.

“He’s not perfect,” Peralta said of Ahmed. “We all make mistakes. These types of things happen, but he was able to, as a professional, to come and do something to help the team to win. And with that good at-bat that he had, that’s why we were able to win the game.”
