No.2 seed Elise Mertens and 2021 US Open champion Emma Raducanu will have to delay the start of their 2025 seasons on the Hologic WTA Tour after withdrawing from the ASB Classic on Tuesday. 

Both players withdrew ahead of their season debuts. Mertens withdrew citing a right ankle injury. Raducanu withdrew due to a low back injury. 

“I’ve tried my best to be ready," Raducanu said in a statement. "I love Auckland and the fans here. But unfortunately, I’ve picked up a back niggle and I won’t be ready in time."
