Ivashka, who levelled his ATP Head2Head against Andujar at 1-1, dictated proceedings. He broke the Spaniard’s serve four times and served eight aces to advance to the second round.
“I think it was a good match for me,” Ivashka said following the win. “I played very clean, I was serving really good.”
“He’s a great opponent, he has a lot of experience and I hope it’s going to be a great match,” Ivashka said. “He’s a great guy and it’s always nice to play against him.”
The 27-year-old now holds a 29-14 record in 2021, which includes 12 victories in his past 14 matches. Ivashka lifted his first ATP Tour title last month in Winston-Salem, and currently sits at a career-high No. 45 in the FedEx ATP Rankings.
