Last year, Kyle Farnsworth gave up 15 home runs in 60 innings. In his career, Farnsworth has allowed a .441 slugging percentage to left-handed hitters.
Jim Thome is a left-handed hitter with 541 career home runs.
Over the past three seasons, Chicago's U.S. Cellular Field has been the most homer-prone ballpark in the American League, both generally and for left-handed hitters specifically.
With two outs in the bottom of the eighth inning and two White Sox on base, the Royals held a 2-1 lead. Thome was coming up. If there's a single pitcher in the majors who shouldn't be facing Thome in that situation, it just might be Farnsworth.
Yet, face him he did. Threw Thome a fastball down the middle, he did. Gave up a long, three-run, (eventually) game-losing home run, he also did.
And Royals manager Trey Hillman? He sat on his hands and watched it happen. That's what he did.
