The Best and Worst of Marcus Semien
A cursory examination of the WAR leaderboards for shortstops in 2015 shows a few surprising developments. At the very top, we have the nice blend of defensive and offensive aptitude in Zack Cozart, and the mainly defensive-minded duo of Brandon Crawford (who has surprised at the plate this year) and Andrelton Simmons. Then, where we might expect a name like Ian Desmond or Troy Tulowitzki, we instead have Marcus Semien.
It’s only May, so we’re still dealing with the usual parts of the game that suffer from small sample size issues when it comes to player comparison and valuation, like BABIP and defensive metrics. Still, there’s something about Semien being toward the top of the boards that warrants our attention: not only is the A’s shortstop there because of his offense, he’s there despite his defense.
On Sunday, we saw both the best and worst of him. Let’s start with defense. During the bottom of the second, Logan Morrison hit a routine one-hopper up the middle to Semien, who was shifted along with the rest of the infield. The outcome was one Athletics fans have wearily gotten used to:
That was the 24-year-old’s 9th error of the season, briefly tying him with Ian Desmond and Danny Santana for the league lead, that is until he moved into sole possession of first by making another on Monday (he made one last night too). If you don’t like errors, Semien sits at -1 runs by DRS, good for 20th in the majors.
