Ruben Tejada has taken a big step back in his development this year. At times, he’s just been plain bad.
He’s hitting .209/.269/.264. He does have 10 doubles, which is good for second on the team, but that may speak more to the makeup of the roster than it does to Tejada’s extra base hitting ability. As a shortstop, a team will usually put up with a lack of offense as long as you play solid defense. But Tejada hasn’t done that.
He’s already made 8 errors (6 of them throwing) after making only 12 last year. A look at advanced fielding metrics, which is still somewhat of an inexact science, shows his rPM (Plus/Minus runs saved above average) at -7. I’m not going to pretend I know exactly how this is calculated, but it’s not good. His rPM last year was -3.
You don’t need a supercomputer to see how he’s struggled in the field, however.
