Tendering Casey Fien: Pros And Cons

The bullpen has been a primary area of interest for me lately, one that I've written about a few times recently since I view that unit as one where the Twins can make very meaningful and impactful improvements during the offseason.

Is bringing Fien back a step in the right direction? He turned 32 last month and his strikeout rate has declined in each of the past two seasons. This year, his 5.8 K/9 rate ranked 125th out of 137 qualified relievers.

For a team that ought to have a clear focus on building a more powerful bullpen after finishing 2015 as the only team in the majors with a K/9 rate below 7.0 from its relief corps, bringing back a setup man who has struggled to miss bats like Fien is, on the surface, questionable at best.

In fairness, however, there are a few other factors to be taken into account.

For one thing, Fien's drop in strikeouts did not coincide with a dip in velocity, reducing concerns that his arm is running out of gas. Indeed, the heightened contact rates appeared to relate to his health, as the strikeouts mostly dried up in the middle of the summer, around the time he was dealing with a shoulder strain. By season's end, he had evidently put those those issues behind him, finishing with a 2.91 ERA and 17 strikeouts in 21 innings over his final 20 appearances.

And even with the lack of whiffs, Fien had a good season overall. His 117 ERA+ was his best in a full season. His 1.09 WHIP was undeniably excellent, and exactly what you want from a pitcher getting high-leverage chances. His ability to keep runners off the basepaths was driven in part by his elite control; among qualified relievers, only Oakland's Evan Scribner had a walk rate lower than Fien's 1.1 BB/9.

It was the third consecutive season in which Fien has ranked near the top of the league leaderboard in that category, and that is not something to be overlooked.

Ultimately, when you account for the righty's proclivity for pounding the strike zone, along with his enduring mid-90s velocity, his strong finish, and the relatively low cost of keeping him around (in the Offseason Handbook, we estimated that he'd make $2.5 million in 2016) the decision to tender him a contract is a very defensible one.

The downward strikeout trend is troubling, however, especially on a team that desperately needs to find more K's in the bullpen.

All things considered, if Fien is the No. 3 right-hander in the bullpen heading into next season, he's nice to have on board. If he's the second option, routinely being called on to pitch the eighth inning, then some of the concerns surrounding him become magnified. So much will depend on what happens with Trevor May and with the remaining offseason moves.
