Marcus belted 27 home runs in 2016, the most by an A’s shortstop since Miguel Tejada had 27 in 2003. He became just the fifth shortstop in Athletics history with 20 home runs and his 42 homers over the last two seasons (2015-16) were the most by a Major League shortstop during that span. In 2016, Marcus posted career highs in games (159), at-bats (568), runs (72), doubles (27), home runs (27), RBI (75), walks (51), strikeouts (139), slugging percentage (.435), OPS (.735) and extra base hits (56).
Marcus was the A’s recipient of the MLB Players Alumni Association’s Heart and Hustle Award in 2016, which honors active players who demonstrate a passion for the game of baseball and best embody the values, spirit and traditions of the game.
