Broadly viewed, Terry Ryan's dismissal as Twins GM a week ago came as a result of bad decisions in talent evaluation. You don't fire someone at the top of the personnel food chain, after all, if a roster is stocked with complementary, talented pieces.
Narrowing the view, pitching was the critical area with the most missteps, both in terms of organizational development and outside acquisitions.
I'd posit there is another narrow view of what went wrong — much of it, still, in the pitching department but also spread across the roster.
It is this: the Twins under Ryan fell victim too many times to small sample size decision-making, particularly when the small sample was positive. Perhaps it comes from believing too much in your own scouting. Maybe it comes from wanting to believe.
In assembling this year's club, the Twins overvalued Kevin Jepsen and Trevor May as back-end bullpen guys based on strong performances down the stretch last year. Jepsen's ERA ballooned to 6.16 this season before he was dumped. May is still battling back from a brutal stretch that has left his ERA at 5.66.
Massive hopes were pinned to Miguel Sano and Eddie Rosario (and to a lesser extent, Byron Buxton). While the Twins were measured in their expectations to a degree, officials also weren't shy about proclaiming the team could contend for a playoff spot this season. And to do that, it's pretty clear those guys would have needed to play crucial positive roles.
Going back in time, the Twins rewarded Ricky Nolasco for a decent 2013 season in the National League with a four-year, $49 million deal — never mind that he had been subpar from 2009-2012. Predictably, he's been subpar since signing. Rather than let Phil Hughes' initial three-year, $24 million contract play out after he excelled in his first season (2014), the Twins added three years and bigger money to it. Hughes very well might bounce back in 2017 once he is healthy, but right now it's fair to question the wisdom.
There are other examples, but I'll stop the long windup here and get to the headline, which is about Sano's third base defense.
