So, the Box Score says we only committed 1 error. However, in that 4th inning we had Bielak forget how to run to 1B on a grounder to his left, Pena fail to get to a double play ball b/c he was playing so far to the 3B side, and Bregman unable to come up with a grounder hit sharply to his left that kicked off his glove. Bregman also had that long throw after stepping on 3B that went high. Both those Bregman plays are pretty tough, and I would never call them errors, but that's the kind of stuff that can make a difference.
In the end, we still only scored 2 runs, but overall the defense was far from stellar.
All of this, of course, is just, like, my opinion
