Fatherhood has affected Andy Murray's form, according to former British number one Annabel Croft.
The world number two lost to Grigor Dimitrov in the third round of the Miami Open.
Murray, 28, returned to playing earlier in March after becoming a father and made an early exit from Indian Wells.
"Life has just changed for him and he's just trying to regain momentum but at the moment, it's a bit of struggle," Croft told BBC Scotland.
"He [Murray] hasn't played a lot of tennis this year. He took time off when his wife had their first baby," she added.
