Jazz Chisholm Jr. has The Seventy Percent Solution. While most athletes talk about the urge to give 100% or even 110%, the New York Yankees infielder thinks his success since returning from the injured list has been caused by limiting his intensity. Chisholm hit a three-run, go-ahead homer in the first inning and four RBIs to spark the Yankees over the Boston Red Sox 9-6 in the first meeting this year of AL East rivals. He says: “Just go at 70%. That’s what’s been working for me.”
