Big Sascha is no longer part of Team Serena.
Serena Williams' eight-year working relationship with hitting partner Sascha Bajin has apparently come to an end.
The man Serena affectionately calls "Big Sascha" referenced the split in a tweet today thanking the world No. 1 for their time together.
Bajin is now working with Williams' friend, former world No. 1 Victoria Azarenka.
Bajin, who was recovering from injury, did not make the trip to Melbourne where the top-seeded Williams captured her 19th Grand Slam title at the Australian Open.
They could run into each other this month in Indian Wells as Serena is scheduled to return to the tournament for the first time since 2001.
