If you look at Bo's error. He had a slight bobble, but still got the ball fairly quickly to second. If you look at where the runner was going from 2nd to 3rd he was still along ways off the bag when Bo made the throw to second. Fowler must have had an incredibly large secondary lead and quick reactions to the hit to get to second as quickly to 2nd as he did. Even with the bobble, his throw to second would have been in time to get 95% of runners. Fowler doesn't get enough credit for that play. Still even with the bobble he had plenty of time to get the runner at first. These are the learning experiences young players go through. The throw to first later in the game was likely an over correction to get the sure out.
Bo has really good range. The diving play to his right he made the game before put that range on full display despite not getting the runner. He's quick too. He makes those diving plays and pops up. He has a solid arm. He might not have the best hands but I don't think he's a tire fire at short like Torres might be. Bo's very capable of making some highlight real plays, he just won't show the consistency like a tulowitzki did at short. He's more than capable of handling the position.
I'm more worried about Bo's at bats. He took a lot of walks in spring training and he's had zero in the regular season. He's just pressing, like many of the hitters. I have no doubt he's going to turn it around with the bat. There's a bunch of kids pressing. Vlad and Randall are carrying the team.
