Without the same amount of information monitored as this blog has for the Nationals, it is impossible to ascertain whether the Tigers' fall-off in performance is associated with bad fielding. However, there are several obvious pieces of information to draw from these numbers. One is that the Tigers' outfielders aren't doing very well. On all measures we see negative numbers except for J.D. Martinez' RZR and DRA, and Rajai Davis' DRA. But the DRA numbers aren't much above average.
The infield pffers a slightly better picture, with Ian Kinsler and Miguel Cabrera doing well under UZR and DRA is really enthusiastic about Cabrera. However, RZR sees the left side of the infield as quite a problem, with both Andrew Romine and Nick Castellanos well under the league average.
I do have data for overall team fielding going back some weeks. The Tigers' team UZR has fallen quite sharply over the last ten days to two weeks, from average-ish to moderately bad. (UZR thinks the worse teams are the Indians and Astros). The Tigers are probably at the fringe of what is tolerable. Defensive Runs Saved sees the picture a bit worse, with the Tigers being the fourth-worst team in MLB. RZR shares UZR's ranking.
On pitch framing, Alex Avila is one of the worst in baseball, with only three catchers with lower scores.
