Jesse Winker remains a top candidate for improvement based on Statcast data.

We looked at players whose expected statistics differed significantly from their actual numbers in the past two weeks. The two metrics were wOBA — weighted on-base average — and slugging percentage. The third number often associated with expected ratios is used in almost every fantasy baseball league: batting average.

Some formats have moved from batting average to on-base percentage, but the vast majority — especially those listed as “standard” — lean on batting average as one of the main categories. Even if it does not pertain directly, we can, again, look at the discrepancy between the surface numbers and what lies beneath them.

Below is a table of batters sorted by difference between xBA and BA to identify the players who have the most significant gap. Players with at least 70 batted balls in play were used. For batters, a negative difference is better, suggesting a positive correction. For reference, the league averages as of the time this table was created are .232 BA, .251 xBA, and a -0.019 difference.

Below is a table of pitchers sorted by difference between xBA and BA to identify the players who have the most significant gap. Players with at least 70 batted balls in play were used. For pitchers, a positive difference is better, suggesting a positive correction. For reference, the league averages as of the time this table was created are .232 BA, .251 xBA, and a -0.019 difference.
