Former Cal star Daulton Jefferies will make his MLB debut on Saturday, A’s manager Bob Melvin announced Friday. 

The 25-year-old right-hander will start in the first game of a doubleheader against the Texas Rangers.

Last season across the A’s Single-A and Double-A affiliates, Jefferies posted a 3.42 ERA with 93 strikeouts in 79 innings. 

“He seems to be a real composed kid, does a lot of the intrinsic things well, quick to the plate, has great command obviously, if you look at his numbers over the years as far as walks, keeps the ball on the ground,” Melvin said on Friday. “A guy that obviously had to go through a couple of issues with some injuries, but finally back to the point where he gets to make his major league debut and he was pretty excited when I told him today.”

Jefferies missed part of his junior year at Cal in 2016 with a shoulder injury and then underwent Tommy John surgery in April 2017, his first full year in the A's organization. 

Jefferies’ noticeably excellent strikeout-to-walk ratio across two levels in 2019 was brought up during the Melvin's media availability.

In 21 games with Double-A Midland alone, Jefferies boasted a 10.29 K/BB ratio.

“It’s something that’s always been there for him,” Melvin said.  

Jefferies was drafted by the A’s No. 37 overall in the 2016 draft and was always considered a well-regarded prospect, but some of those injuries had him lower in the rankings.

 

On Saturday, the A's and their fans finally will get to see what Jefferies has to offer.
