2020 Fantasy Outlook
April 2017 Tommy John surgery cost Jefferies almost two full seasons. His below-average recovery time was worrisome, but he came back with a vengeance, logging a 93:9 K:BB in 79 innings, primarily at Double-A. The No. 37 overall pick in 2016 sat at 95 mph with his fastball in his final start of the year and had his signature plus changeup working throughout his first full campaign. The A's were very careful with him -- he threw between three and 3.2 innings in all 26 appearances -- so his numbers are a little inflated due to the fact that he never had to face the same hitter more than twice. The 6-foot, 185-pound righty still needs to prove he can handle a starter's workload and needs to sharpen his breaking ball. Even so, the potential for a plus fastball, plus changeup and plus command from a pitcher who should join the big-league rotation this summer makes him relevant in all formats. Read Past Outlooks
Returns to alternate site
The Athletics optioned Jefferies to their alternate training site Sunday.
ANALYSIS
Jefferies was designated as Oakland's 29th man for Saturday's doubleheader with the Rangers and made his MLB debut in the first game of the twin bill. He was roughed up in the start, lasting only two innings while giving up five runs on five hits and two walks. Oakland will require a sixth starter in the final week of the season with a doubleheader in Seattle on tap for Sept. 26, and Jefferies or Mike Minor would seemingly represent the most logical options to fill the opening in the rotation.
