From Grantland......... Worst of all might be Danny Santana, who ranks last in the majors in DRS and has somehow already cost his team six runs on defense in just 12 games. Thanks to a seemingly excellent rookie season in 2014, Santana won the Opening Day shortstop job, but his shiny .319/.353/.472 effort last year can largely be chalked up to a tremendously flukish .405 batting average on balls in play. In 2014, Santana struck out five times more than he walked, and he projected as one of MLB’s most likely regression candidates heading into this season. Instead of a gentle pullback, the early returns have been brutal: a .195 batting average, just one extra-base hit, 13 strikeouts, and no walks in 42 times at bat. Throw in the rough fielding and Santana might be the worst player in the majors through these first two weeks.
