"He's got really good stuff," Moore said. "He's had some bad luck with some injuries. He'll get going, be really dominant. He's had some setbacks injurywise. But we feel really comfortable."
Fillmyer, 23, recorded an 11-5 record with a 3.49 ERA at Class AA Midland in 2017. A fifth-round pick in 2014, he has a career 3.78 ERA in 392 2/3 innings in the minor leagues. He was added to the A's 40-man roster this offseason. He will likely offer rotation depth while starting the year in the minors, Moore said.
For now, the addition of Hahn gives the Royals an assortment of back-end-of-the-rotation options as spring training looms in a matter of weeks. With Danny Duffy headlining the rotation, and Ian Kennedy returning for a third season, Hahn will compete for a spot with a group that includes Nathan Karns, Trevor Oaks and Jakob Junis.
The rotation is also expected to include veteran Jason Hammel, though he could also find himself as a casualty of a another salary-dumping trade. Hammel, 35, is owed $11 million entering the second season of a two-year, $16 million contract. Yet as Moore executed a deal on Monday, he reiterated that no such trades were imminent.
"If the right situation comes along," he said. "As you know, I've made our objectives really clear. We want to rebuild our farm system, and we're certainly focused on managing our payroll more efficiently going forward."
The club has stated that its payroll will likely be somewhere in the $105 million to $110 million range in 2018. The current projections -- before a possible Hosmer signing -- approach that number.
Moss, 34, is returning to Oakland, where he excelled early in his career, after batting .207 with 128 strikeouts in 118 games last seasons. Buchter, 30, posted a 2.67 ERA in 27 innings last season after being acquired from San Diego in a midseason trade. He will make close to the league minimum this season and is under club control for another four years.
