This article is part of our MLB Barometer series.
For the last Barometer of April, we'll look at the players whose stock has most improved based on their performances in the first month of the season. Rather than simply pick out the players myself, I'll turn things over to the numbers. I'll present a series of tables showing which players' performances have been most out of line with their respective draft positions.
These tables represent more of a results-based analysis than is usually found in this column, but it's worth remembering that fantasy leagues (at least every league I've ever seen) deal in actual batting averages and ERAs rather xWOBACONs and spin rates. The players found in these lists might not continue to perform at their current levels, but the value they've produced is already in the books. We'll investigate a few players who do seem to be legitimately reaching new heights or new depths.
These lists were created by comparing each player's NFBC ADP with his ranking on the Earned Auction Values list. The latter page was set to show values for a 15-team league with standard NFBC settings (14 hitters and nine pitchers), with 70 percent of the budget spent on hitters. I ignored players whose underperformance was primarily due to injuries preventing them from taking the field or delayed callups preventing them from accruing value.
