Andy Murray hopes a move from America's West Coast to the East for the Miami ATP Masters will let him move on from a dismal outing at Indian Wells.
"I want to do well here, it's obviously an important week for me," said the world No. 5 from Scotland, who admits his tennis hit a low 11 days ago when he was humiliated in his opening match at Indian Wells by 128th-ranked American Donald Young.
"Indian Wells was tough, because I didn't feel like I did myself much justice on the court. I don't mind normally, like, if you lose and you feel like you've given everything you can, you've left everything on the court.
"That's when it can be easier to get over the losses. But I was disappointed in myself last week."
There can be no more amiable spot for the Scot to begin making some winning changes. He has owned a Miami flat for three years and frequently uses the Crandon Park venue for training in December.
But his fortunes at the tournament have been mixed. He reached the 2009 final against Novak Djokovic but lost in his opening match a year later to Mardy Fish.
"I do like playing here, obviously this tournament is hopefully where I start to play better again and have the right mindset going into matches.
"Last year here was a pretty low point for me. I need to try and get better before the clay," added Murray, who for the second year in a row has had to digest an Australian Open finals defeat.
While Murray fights for respectability. Roger Federer can only shrug off suggestions that he is on an irreversible downward spiral with only one title and three defeats this season to Novak Djokovic.
The record-setting 16-time Grand Slam champion was at his ease Wednesday after several practice sessions at the venue where he will be the third seed behind Rafael Nadal and Djokovic.
Serbia's Djokovic has seized the world No. 2 ranking and is riding an 18-0 hot-streak this season, including his triumph over Murray in the Australian Open final.
Federer's only three defeats this year have come at the hands of Djokovic, at the Australian Open, Dubai and last week at Indian Wells.
"It depends on who says that," the Swiss said of pundits predicting his demise as a dominant power.
"I don't know if it's 5 percent saying it, 95 percent saying it. At the end of the day, it doesn't matter too much to me if someone is saying that or not. I still think I've had a great six months.
"I feel like I'm playing really good tennis, and right now Novak is just a bit better than the rest. And that's OK," added Federer, who will face either Czech Radek Stepanek or Italy's Fabio Fognini when he makes his second-round start this weekend.
With his half-decade of total domination of the sport where he set record upon record, the 29-year-old Swiss is well-aware of what a roller-coaster staying at the top can be.
"I've gone through phases like this on multiple occasions with Rafa (Nadal), with (Andy) Murray, with even (Andre) Agassi and (Lleyton) Hewitt and (Andy) Roddick and so forth. It's just something that's part of the game."
With the seeded players enjoying first-round byes, former US Open champion Juan Martin Del Potro was among the bigger names in action on Wednesday.
The Argentinian continued his return from 2010 wrist surgery, reaching the second round with a 6-4, 6-4 victory over Brazil's Ricardo Mello.
Former top five player Nikolay Davydenko of Russia fell to South African Kevin Anderson 6-4, 6-3.
In women's play, Japan's 40-year-old Kimiko Date-Krummm advanced along with China's Peng Shuai.
