Weekly Hot Seat Update: April 10, 2015

April 10, 2015

After elbow injuries to Joe Nathan and Jenrry Mejia and the recent demotion of Brett Cecil, three of the shakiest closers in the game have already been replaced. Who starts the season on the hot seat? And who stands to benefit if they falter?

5. Miguel Castro
Koji Uehara‘s impending return means that we didn’t even consider Edward Mujica for this spot. Instead it goes to the putative head of the brand-new Toronto closer committee: 20-year-old future starter Castro, whose right elbow (and its single tendon) was expected to start the season at Class A Dunedin. Castro’s rapid rise makes for a great story, but if he falters, it’ll be simple for the Jays to try out fellow youngster Roberto Osuna or return to Cecil.

4. LaTroy Hawkins
The 42-year-old already has his first blown save of the season, and PECOTA predicts that he’ll give up almost as many runs this year (36) as he earns strikeouts (43). Not exactly a recipe to lower a manager’s blood pressure. Walt Weiss can turn to Adam Ottavino, John Axford, or (when he gets back to the majors) perpetual “closer of the future” Rex Brothers.

3. Jason Grilli
Stepping into Craig Kimbrel’s golden cleats is the 38-year-old Grilli, who has an extensive history of injuries, and an apparently revitalized Jim Johnson lurking behind him. The Braves will give him the first shot at the job, but they’ll move on in a hurry if he performs like he did last season in Pittsburgh.

2. Dellin Betances
Betances, one of the breakout stars of 2014, struggled all through spring training, and hasn’t been much better now that the games count. Although the righty seems to have regained his missing velocity, control problems continue to plague him. He’s already in a platoon situation with lefty Andrew Miller, who’s a real threat to take the job and make it his own.

1. Chris Hatcher
Converted catcher Hatcher got the Dodgers’ first save of the year, but he might not be in line for too many more after getting blasted in a tied ninth inning on Tuesday. Joel Peralta, Hatcher’s main competition for the job in Kenley Jansen‘s absence, may have had a rough 2014, but he’s posted a consistently above-average WHIP and K rate over the last five years — and his first two outings so far this year have been scoreless, earning him a win and a save.
