"Walking out here. being back here in Melbourne is an incredible feeling and hopefully I can keep it going a little bit longer".
It was a near miss for the 19-time Grand Slam victor, who holds the record for the most weeks at No. 1 with 302 but has not peaked the rankings since 2012.
"I'm giving them maybe more than just like: "My forehand worked well, the second serve I have to improve".
"In the immortal words of Ron Burgundy, it's great to be here with two tennis legends, Roger Federer and John McIntosh", Ferrell said. "I've practised with him, played singles and doubles against him too so you have the information you need", Federer said of his German opponent.
Struff looked good in his opening match and clearly has some shotmaking ability that's needed to counter somebody like Federer.
The 36-year-old broke Struff at 2-2 in the first, with the second set following in similar fashion.More news: Orlando's Arron Afflalo suspended 2 games for altercation with Minnesota's Nemanja Bjelica
"If you want to get to the top, you've got to be able to play in all conditions, but sure it has helped to play now rather than during the day".
"Not if their fast enough", Ferrell said, drawing a laugh from the crowd.
Federer will begin his Australian Open defence against Aljaz Bedene in the first round as he looks to get his season underway with a title.
The Swiss champ is coming off an extraordinary 2017, when he won a fifth Australian Open title and a record eighth at Wimbledon, after returning from an injury lay-off. "I wish they would let loose and be themselves". But if Federer was caught off guard, you'd never know it, which was an wonderful feat in itself since Ferrell was in fine Burgundy form.
Federer won in 99 minutes and will face Germany's Jan-Lennard Struff next.
