Here’s a list of American League starters who’ve compiled the best DER so far (minimum of 12 innings pitched). DER is the percent of batted balls that have fallen in for hits. A low DER is an indication that the pitcher has great fielders behind him or gives up “fieldable” batted balls, or is just plain lucky. Most of the guys on this list will see their DER increase.
