Roster moves
The Arizona Diamondbacks made the following roster moves. The D-backs’ 40-man roster is at 40.
- Recalled from Triple-A Reno: LHP Philip Abner (No. 50)
- Optioned to Reno following last night’s game: RHP Andrew Hoffmann
Probably a necessary move, simply for an extra arm. Though the chart above doesn’t necessarily show it, the D-backs bullpen has been wheezing. Jack went into more detail about that earlier today, due to a combination of short outings by starters and close contests. But it is interesting to note that Arizona are below MLB average, both in terms of bullpen innings, and batters faced. They are above the median
in relief outings – but at 101, only five percent above it (96). So why is it a problem for Arizona? Part of the reason might, oddly, be the stability of the D-backs bullpen.
This is only the second “true” change to the bullpen since Opening Day, over a month ago. The first was DFA’ing Joe Ross, who was replaced by Taylor Rashi. When he was optioned to Reno to make way for the return of Merrill Kelly, Brandon Pfaadt got bumped to the bullpen. But that has been it. Consequently, Arizona has used only 11 relievers all year, and that includes James McCann. The teams atop the bullpen usage by innings, the White Sox and Nationals have also used the most relievers – a startling twenty-one already in Chicago’s case, almost twice as many as the D-backs. Arizona has been leaning heavily on the same arms since the beginning of the season.
We can see this if we look at the average number of outings per reliever. Take the total number of relief appearances, and divide by the number of relievers used. For Arizona that comes out to 9.2 games per reliever, well above the median (around 7.5). The real problem is the lack of reliable bullpen arms for Arizona. We don’t have many credible alternatives in Reno who can be rostered in and out to give others a blow. Not helping matters: as Jack notes, only Hoffman and Juan Morillo have options, so can be sent to the minors. Well, technically, Pfaadt does too, but I’d not expect him to be enjoying buffet food anytime soon.
