Saving Detroit: Reliever Relief

Despite being pretty good at almost every aspect of building a winning baseball team, the Detroit Tigers have, for years, had as difficult a time finding a reliable closer as the Cleveland Browns have finding a quarterback. Even reading the names Jose Valverde and Joe Nathan is enough to make most fans shudder, and, unfortunately, it’s come time to add Francisco Rodriguez to that list.

There were reasons to be hopeful when Rodriguez came over to Detroit before last season. Even though, at thirty-four years old, he wasn’t the fire-breathing, overpowering force he was in his younger days, it looked like he’d traded some heat for wisdom and found a way to continue to succeed as he aged. The active saves leader did pretty well last year, and, even if there were some missteps in key moments, it was hard to be too disappointed with the overall body of work. He even seemed to help teach manager Brad Ausmus a helpful lesson about bullpen management, as Ausmus slowly broke out of the conventional mold and began using Rodriguez in high-leverage four-out situations rather than rigidly reserving him for the ninth inning alone.

Baseball famously is a game without a clock (at least for now), but humans lack such an exemption, and the clock appears to have run out on Rodriguez in his age-thirty-five season. After single-handedly blowing two games over the weekend, it sure seems like Rodriguez has turned into a dip-filled pumpkin. By one measure, Win Probability Added, he’s done more to help his team lose than any other reliever than all but one other reliever in baseball.

It’s tough to pinpoint exactly what’s wrong with K-Rod this year. His velocities are down a little bit, but they’ve been going down pretty much steadily over the course of his career. That’s nothing new, and it’s why he started prioritizing offspeed pitches over his cooling fastball as he got older. Other indicators, including location, pitch usage, and release points, all look as reasonably expected. The results don’t lie, though; batters are absolutely hammering him this year:

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 article posted this evening shows:

The Tigers’ margin for error this season is extremely narrow, and Rodriguez just cost them two wins on an important West-Coast roadtrip. They don’t have time to let Rodriguez find himself in game-ending, high-leverage situations. Ausmus needs to rearrange his bullpen immediately. It already was a thin crew, but the status quo won’t do. It’s time to promote the Wilsons and find out if the rest of this motley bunch can handle a heavier load.
