Johnson and Loschiavo posted a list score of 406.83 in the final, moving up two spots after placing sixth in the morning preliminaries with a nearly identical total (406.58). They scored no lower than 72 points on any of their eight optionals over two lists, and three of their dives scored more than 80 points, including their final dive of the day -- a back 2 ½ with 2 ½ twists that earned 83.16 points.
China's Chen Aisen and Yang Hao (498.48) won gold, Russia's Viktor Minibaev and Aleksandr Bondar (458.85) took silver and Patrick Hausding and Sascha Klein of Germany (440.82) claimed the bronze.
Johnson won an Olympic silver medal in synchronized 10-meter with three-time Olympian and Purdue alumnus David Boudia in 2016 after making his debut on the world stage in 2014. With this being just Loschiavo's second international meet and first World Championships, Johnson was impressed with the way his new partner performed in his debut on the world stage.
"I'm proud of Brandon for the way he dove. I'm really proud of his ability to stay in the moment. If he missed something, he'd come right back with a good dive. He's in a position I was in back in 2014 with David (Boudia). I know exactly what he's thinking, what he's feeling, but the way he keeps his demeanor and the handles the pressure and just really enjoys it is inspiring to me," Johnson said. "I love diving next to him, and I'm excited to see how this synchro pairing grows as we train together every day for the next few years."
Loschiavo said having the veteran next to him certainly helped.
"I could have fixed a few things here and there, but I'm pretty happy with my performance. Having Steele next to me was really helpful so I could try to follow him and have the same demeanor as him," Loschiavo said. "We can definitely grow from this."
Johnson and Loschiavo began their partnership in April by winning the 10-meter title together at USA Diving's Synchronized National Championships. Additionally, both Boilermakers were platform All-Americans at the 2017 NCAA Championships.
Boudia and Johnson finished fifth together at the 2015 FINA World Championships.
Johnson competes again Wednesday on 3-meter, the last of his three events at this year's World Championships. Prelims are set for 4 a.m. ET and the semifinal at 9 a.m. The 12-diver final is slated for Thursday at 12:30 p.m. ET.
Also on Monday, Maria Coburn and Alison Gibson finished 11th in women's synchronized 3-meter. They tallied a five-dive total of 252.42 points in a meet in which they initially weren't slated to compete together. Coburn had qualified for the World Championships in 3-meter synchro with Olympian Kassidy Cook, but Cook withdrew due to injury. USA Diving's coaching staff determined Gibson would fill the spot to dive with Coburn, and the duo has had limited training together.
China's Shi Tingmao and Chang Yani scored 333.30 to win the women's 3-meter synchro gold. Jennifer Abel and Melissa Citrini Beaulieu of Canada took silver with 323.43 points, and the Russian pair of Nadezhda Bazhina and Kristina Ilinykh were third with 312.60 points.
The two American teens were sixth with 283.65 points in the morning preliminaries but had some struggles in the finals when they scored no higher than 59.52 on any of their dives. They scored more than 60 points on all three of their optional dives in the preliminaries.
Indoor diving events at the FINA World Championships continue through July 22. Tuesday's competition features Jessica Parratto and Delaney Schnell in individual women's 10-meter and David Dinsmore and Krysta Palmer in the mixed team event.
