With the series win in Oakland already clinched, the club has matched the 1926 Yankees' all-time franchise record by winning each of the first five series of the season. Only one other club in team history started with as many as four series wins in a row, the 1922 Yankees.
This is the Yankees' best 14-game start since 2003, when they were also 11-3. According to the Elias Sports Bureau, the Yankees are the third defending World Series champions -- and the first in 88 years -- to win their first five series. The 1904 Red Sox and 1922 Giants were the others.
"By no means have we played perfect baseball, but we've played it at a very high level," Girardi said. "I'm very pleased with the way we're playing. You're never going to have times where 25 guys are on top of their games at the same time, but you can still wish for it."
