Gleyber Torres has been the most productive Yankee in the month of August. After trade rumors and only a decent first half, he has proven his worth as one of the very best hitting second baseman in all of baseball. Other than Jose Altuve (who is not a qualified hitter due to missed time), no second baseman in the American League has a higher wRC+. His overall value is dragged down by poor baserunning and average defense, but he is still on pace to succeed 3.0 fWAR on the season producing well above most other Yankees.
His second half success has been driven by multiple factors, but the most interesting development has been his extremely effective toe tap with two strikes.
