Diamondbacks Acquire Reliever Cody Hall

Diamondbacks add a bullpen depth piece

Allan Henry-USA TODAY Sports

The Diamondbacks make another minor bullpen addition with the acquisition of RHP Cody Hall for a PTBNL or cash. To alleviate fears, said PTBNL won't be a top prospect and I believe the deal will be most likely for cash. Hall will compete for one of the bullpen spots. Brad Ziegler, Daniel Hudson, and Andrew Chafin are locks in the bullpen with one of the LOOGY candidates also making the team, so that leaves 4 bullpen spots open. I believe that Silvino Bracho will land one of those spots, so it's realistically down to 3. Hall recently turned 28 years old and got his first MLB action last season for the San Francisco Giants. Hall posted a 6.48 ERA in 8 1/3 IP for the Giants, which also produced a 4.81 FIP and 4.49 xFIP. Obviously that type of production won't cut that at the Major League level.

Looking into his AAA numbers from last year, he posted a 3.46 ERA and 3.70 FIP. Hall has ascended the Giants minor league system with double digit K/9 rates, although he hit a speed bump last year when his AAA rate dropped to 7.32. A 7.32 K/9 rate is typically below average for a reliever, especially when going against a 3.46 BB/9. At the major league level, that does not translate very well so an improvement of both rates are necessary. Hall features a fastball, slider, change-up combination with the fastball in the 92-95 range and a slider that graded positively on Fangraphs. So his upside can be hard to project, but the move presents little downside for the Diamondbacks. Since Hall was on the Giants 40-man roster before the trade, he will also count towards the Dbacks 40-man roster. He has options remaining on his contract, so they could just option him to Reno if he doesn't make the roster.

The Diamondbacks also have Daniel Gibson, Jake Barrett, Matt Stites, Evan Marshall, and multiple other candidates competing for 3 bullpen spots, so whoever emerges from that group will wind up on the 25-man roster. Marshall is a likely candidate for the disabled list due to the head injury suffered after taking a line drive to the side of the head. It is truly an open competition with all the candidates holding their own flaws. The acquisition of Cody Hall just adds another name to the competition.
