However, the ways in which he produced his value shifted somewhat. His 25-point gain in on-base percentage was offset by a 37-point drop in slugging. He fell from hitting one homer every 23 plate appearances in 2016 to one every 38.6 last season, but his stolen base rate nearly doubled, as he stole one bag every 32.2 plate appearances after stealing one every 62.1 the year before. He should remain a strong enough power-speed contributor this season, albeit with a lower batting average, and he could back some power with improved wrist strength following an offseason of rest. The combination of power and speed at the position should be valuable -- and potentially underrated -- heading into the season."},"mostRecentNews":{"date":"Thu Sep 27","news":"Semien went 2-for-5 with a home run, two RBI and two runs in Wednesday's 9-3 win over the Mariners.","spin":"Semien's 15th home run of the season was one of four Oakland long balls on the night in the series finale. The shortstop has only gotten base at a .258 clip over the Athletics' seven games, but he's made a big fantasy impact over that stretch with three home runs and 12 RBI."},"fullName":"Marcus Semien","playerRater30DAY":3.5,"playerRater15DAY":4.6,"playerId":4622}
