Mauer cracks first walk-off homer

The Twins walked off with a victory against the Red Sox last night thanks to a game-ending home run by Joe Mauer, the first walk-off bomb of his major-league career. Mauer had three walk-off RBIs with the Twins prior to Friday, but he has generally struggled in potential walk-off situations. Before his homer, Mauer had batted .176 in at-bats with the potential to record a game-ending RBI, with no extra-base hits in 68 at-bats of that kind prior to Friday.
