Santana, 27, has spent parts of the past two seasons on the Braves’ big league roster, but he hasn’t produced at the plate, hitting just .199/.251/.345 in 184 plate appearances after coming over from the Twins in a minor trade.
More broadly, Santana’s bat has been in a veritable freefall since a terrific rookie campaign with the Twins back in 2014. The switch-hitter posted a .319/.353/.472 slash in 430 PAs that season and even garnered some Rookie of the Year consideration, finishing seventh in the AL voting. However, that rookie effort was buoyed by an enormous .405 average on balls in play — including a particularly fluky .343 average on grounders. As Santana’s BABIP has trended back to more normal levels, his overall offensive output has cratered. In 735 PAs since that time, he’s batted just .219/.256/.319.
