In the history of Major League Baseball, there’s only been one player with the first name Anibal. Anibal Alejandro Sanchez broke into the majors in 2006 with the Florida Marlins. He, along with Omar Infante, came to Detroit in the middle of the 2012 season in a trade. In 2013, his first full season as a Tiger, Sanchez produced by far the best season of his career (6.1 bWAR, 6.0 fWAR, 5.1 WARP). It’s been all downhill since then, though, and his move to the bullpen in 2016 seemed inevitable if only because he remained signed to a starter-magnitude contract that made totally cutting bait a pill too difficult to swallow. Sanchez didn’t make the transition especially well, however, and things have not improved in 2017. It’s come time for the Tigers to release this former fish.
After an especially bad weekend in Oakland capped a rough start to this season for incumbent closer Francisco Rodriguez, I (along with everyone else in the world) wrote on Monday that manager Brad Ausmus needed to demote K-Rod immediately. Ausmus agreed and did so, promoting Justin Wilson to the closer role, although the first run with the new top-line bullpen arrangement showed Ausmus still has room for improvement there. Dynamic, leverage-oriented bullpen management is pretty difficult to accomplish, though, and Sanchez has become a much clearer and more present danger to the team’s success than any further usage optimization of the capable portion of the relief corps.
Sanchez, as a converted starter who used to be good, would seem to be the optimal long relief guy, but he has foundered in that role, and if it seems like he gives up a home run every time he comes into a game, well, you’re not far off.
Last night in Arizona, Sanchez made his first appearance in over a week and immediately surrendered back-to-back home runs to the first two batters he faced. Although the Tigers’ offense had evaporated in the desert heat that night, those two homers Sanchez allowed felt like the real mortal blow that destroyed any hope for a comeback.
This is who Sanchez is at this point. Among qualified relievers in 2017, only one pitcher is allowing home runs at a higher rate than him (none have allowed more, total, than him), and Sanchez has been used more than everybody in the “top” twenty on that list. This now is an untenable situation, and it probably has been for some time. Continue reading

It looks like he’s throwing to the same places– low, and in/away– he usually has, but with much less success. It’s hard (for me, at least) to pinpoint with these various advanced tools exactly what’s happened, but it’s clear that Rodriguez no longer is fooling batters, a veritable death knell for deception-reliant pitchers like him. The way batters consistently chased– and, more often than not, missed– his diving, low and away pitches is something I marveled at last year, my first really watching him and his seemingly simple approach. For whatever reason, though, they aren’t even remotely fooled this year, as the below graph of Rodriguez’s out-of-zone swing rate from a FanGraphs
