A’s Daulton Jefferies To Debut Saturday

By Connor Byrne | September 11, 2020 at 10:23pm CDT

Athletics right-hander Daulton Jefferies will make his major league debut with a start in Game 1 of a doubleheader against the Rangers on Saturday, Susan Slusser of the San Francisco Chronicle tweets. Jefferies is already on the A’s 40-man roster, so they won’t have to make a corresponding move in that regard.

Jefferies, a California native who attended UC Berkeley, is in his fifth season with the A’s organization. The club spent the 37th overall pick on Jefferies in 2016, but his progress was slowed the next season when he underwent Tommy John surgery. Jefferies rebounded in 2019, though, with 79 innings of 3.42 ERA ball and great strikeout and walk numbers (10.6 K/9 versus 1.0 BB/9) between the High-A and Double-A levels. The 25-year-old is now the A’s fourth-ranked prospect at Baseball America and their No. 6 farmhand at FanGraphs.

It remains to be seen whether Jefferies will last with the A’s beyond their Saturday doubleheader, but he may stick around with an impressive performance. The A’s are running away with the AL West, but their rotation certainly hasn’t offered elite production so far. Sean Manaea, Jesus Luzardo and Chris Bassitt have been their best starters in a rotation that hasn’t gotten a lot from Frankie Montas, Mike Fiers or trade deadline acquisition Mike Minor.

    MLB readers of a certain age will probably think of Darren Daulton + Gregg Jefferies, as I did, when they see this headline

      Haha I sure did. Man I remember so much hype being around Jefferies. He did have a couple great seasons but then faded out. But oh well, he still made the majors!

      Yep…then I pictured Dutch and Jeffries on the ‘88-‘89 A’s teams.

    This will tickle Strike Four’s fancy more than a Bernie Sanders rally!

        according to Fangraphs they have an 99.7% chance of winning the division. So I will bet you any amount you want that they will win it!

        For once the playing field is even and Astros can’t cheat the A’s are the top team. They would have won the division last year if it wasn’t for Astro cheating.

          Or is it that the Astros no longer have Gerrit Cole, a top 5 MLB pitcher? Or their closer Roberto Osuna… Or is it that Justin Verlander has been out all year???

          No, no! That had nothing to do with it!

          Acr89 also fails to consider that the Astros have also been missing one of their best bats, Yordan Alvarez, all season. Take 4 of the A’s best players off their team and lets see what happens!
