Red Sox manager John Farrell used to babysit Matt Holliday

(UPI) -- In an odd turn of events Red Sox manager John Farrell found himself rooting against a boy he used to babysit: St. Louis Cardinals left fielder Matt Holliday.

According to MLB, Farell's bond to the Holliday family comes from the time when he pitched at Oklahoma State under Holliday's father, Tom Holliday. The Red Sox skipper eventually went on to coach alongside Tom and even babysat his kids on occasion.

Asked who his father would be rooting for during the World Series, the Cardinals outfielder said he hopes the father-son link is stronger than the co-coach one.

"I would hope he's not conflicted," Holliday joked, "I am his son."

The Boston Red Sox faced the St. Louis Cardinals Wednesday during Game 1 of the World Series. The Boston team came out victorious 8-1.
