Jazz Chisholm Jr. is a very good baseball player that's enjoying the most productive season of his big league career. The New York Yankees infielder has set career highs with 29 home runs, 75 RBI and 56 walks - worth more than four wins above replacement. He's also a home run shy of his first 30-30 season, thanks to his 30 stolen bases.
He's also got a rather unimpressive 13 doubles, a .242 batting average, and has committed 15 errors - including nine at second base, which is one shy of the league lead.
He's very good.
