In order to get their 40-man roster set for the Rule 5 Draft, the A's did a little roster reshuffling on Monday.
Among the casualties from the roster crunch was outfielder Jaycob Brugman, who played in 48 games for the A's in 2017.
Brugman and left-handed pitcher Sam Moll were designated for assignment in order to clear spots for the A's to add right-handed pitchers Heath Fillmyer and Lou Trivino to the 40-man roster.
During his stint with the A's last season, Brugman hit .266/.346/.343 with two doubles, three home runs and 12 RBI. Brugman participated in the recently-concluded Arizona Fall League, but didn't put up great numbers. He his just 1.82 in nine games.
The 23-year-old Fillmyer started 29 games for Double-A Midland and posted a 3.49 ERA in 149.2 innings. He was a fifth-round by the A's in 2014.
Trivino spent time with Midland and Triple-A Nashville during the 2017 season. In 48 relief appearances between the two levels, he posted a 3.03 ERA and struck out 65 batters in 68.1 innings.
Earlier on Monday, the A's acquired outfielder Ramon Laureano from the Astros for right-handed pitcher Brandon Bailey. Laureano was added to the 40-man roster and right-handed pitcher Bobby Wahl was outrighted to Triple-A Nashville.
The Rule 5 Draft will be held on Thursday, Dec. 14 at the Winter Meetings in Orlando.
For the second straight season, Kendall Graveman will get the ball on Opening Day for the A's. And for the second straight year, he'll face Mike Trout and the Angels.
The team made the news official on Tuesday morning.
Last year, in a win over the Angels, Graveman went six innings, allowed two earned runs and struck out seven.
"It's something I don't take for granted. It's an honor and a privilege and [I just want to] try to get the season off to a good start and hopefully be a leader of this staff," Graveman told reporters Tuesday in Arizona.
In four seasons with the A's and Blue Jays, Graveman has a 4.11 ERA in 76 appearances.
UPDATE (Mar. 19, 7:45 p.m. PT): The A's officially announced the Cahill signing on Monday. This story has been updated to reflect that.
On the same day the Oakland A's learned they'd be without Jharel Cotton all season, they signed a familiar face to bolster their pitching depth.
Oakland agreed to a one-year deal with Trevor Cahill, nearly 12 years after the A's drafted him in the second round.
Cahill pitched for Oakland from 2009-11. He started 96 games in three seasons with the A's, going 40-35 with a 3.91 ERA and 1.32 WHIP. Since Oakland traded him to the Arizona Diamondbacks in Dec. 2011, Cahill's pitched for six teams.
The 30-year-old won a World Series ring with the Chicago Cubs in 2016, and pitched for the San Diego Padres and Kansas City Royals last season. In 2017, he went 4-3 in 21 appearances (14 starts) with a 4.93 ERA and 1.62 WHIP.
