Keller has allowed 12 earned runs in five spring innings, giving up 15 hits and three walks while striking out six, DK Pittsburgh Sports reports.
"I mean, the execution, we have to get cleaned up," manager Derek Shelton said. "I think we would have an issue if we didn't see stuff. We have the stuff there. Fastball command has been an issue, and he continued to miss up." If anything, Keller has gained velocity since last season, sitting in the 96 mph range. While his annual spring ERAs have become comical -- his 21.60 ERA is actually one run better than it was during spring training in 2019 (22.50 ERA) -- the team is looking for more improvement than that from Keller in 2021. Fantasy owners might expect exaggerated stretches, both good and bad, from the soon-to-be 25-year-old this summer.
