Tony La Russa announces retirement

The St Louis Cardinals manager Tony La Russa has confirmed his retirement just days after guiding his side to success in the World Series.

The 67-year-old has decided to quit baseball after a 33-season association with the sport, 16 of which were spent with Cardinals.

"There isn't one [factor] that dominates [my decision]," La Russa said. "They all just come together telling you your time is over.

"We went through the season and I felt like it's time to end it and I think it's going to be great for the Cardinals to refresh what's going on here."

St Louis claimed the World Series crown last week after edging out the Texas Rangers 4-3.
