Kuchar, who won a bronze medal at Rio, qualified 16th after tying for fourth at Crooked Stick. He was 11 shots behind winner Dustin Johnson, who had already qualified for the Ryder Cup team.
Holmes was also in that group with Kuchar, scraping into the East Lake field in 28th place overall.
"I've been on a lot of teams with Matt," Love added. "He's got a great attitude for match play. He's a great partner. Like J.B., he's consistent. He's easy to pair. These three guys are who we really all wanted. We're very confident in them."
Love still has one more wildcard to pick ahead of the Ryder Cup, which runs from September 30 to October 2.
