Weems was recalled from Oakland's alternate training site Tuesday.

EDGE Analysis

Burch Smith (groin) and Reymin Guduan (thumb) landed on the injured list, so Weems will provide some much-needed bullpen depth in the short term. Weems will likely be up and down between the majors and the minors for most of the season.

Weems was optioned to Triple-A Las Vegas on Sunday.

EDGE Analysis

The 28-year-old appeared in nine games for the A's last season and had a 3.21 ERA, 1.21 WHIP and 18:7 K:BB over 14 innings, but he'll open 2021 in the minors. Weems should receive a promotion at some point this season as Oakland shuffles its bullpen pieces.

Weems has been added to the roster for the ALDS against the Astros, Matt Kawahara of the San Francisco Chronicle reports.

EDGE Analysis

The Athletics altered their roster construction slightly ahead of the series, adding a reliever in Weems while removing reserve infielder Vimael Machin, who did not make an appearance during the AL Wild Card Round. Weems isn't one of Oakland's higher-leverage options, though he did look good in his 14-inning debut this season, posting a 3.21 ERA and a 31.0 percent strikeout rate.

Weems fired three perfect innings in relief during the first game of Saturday's doubleheader against the Rangers, recording five strikeouts.

EDGE Analysis

As his line implies, Weems was thoroughly dominant, and he recorded his nine outs on an efficient 38 pitches. Performances the caliber of Saturday's are becoming par for the course for the 27-year-old, who's now posted four straight scoreless appearances (seven innings) after surrendering two earned runs to the Rockies in his season debut back on July 28.

Weems was recalled from the Athletics' alternate training site Monday.

EDGE Analysis

Weems spent some time at alternate camp after returning from the injured list Aug. 14, but he'll return to the major-league bullpen. He'll take the place of right-hander Paul Blackburn, who was optioned to the alternate training site in a corresponding move. Weems made two relief appearances at the end of July, allowing two runs on five hits and one walk while striking out five over five innings.

Weems (lat) was reinstated from the 10-day injured list Friday and optioned to the Athletics' alternate training site.

EDGE Analysis

Weems was placed on the injured list with a strained right lat at the beginning of August, but he's healthy enough to return to the mound. While he'll no longer be on the active roster, he'll be able to build back up at the alternate training site and could be an option to fill in as a reliever at some point this season.

Weems (lat) is getting closer to throwing to hitters at the Athletics' alternate training site in San Jose, the Associated Press reports.

EDGE Analysis

Weems went on the injured list Tuesday, but he's apparently making steady progress. Manager Bob Melvin confirmed as much Sunday, saying "I know everything's progressing well" when asked about the hard-throwing reliever. Weems was an early success story for the Athletics after finally making the majors this season, posting a 3.60 ERA and 5:1 K:BB across five innings over two appearances before his injury.

Weems was placed on the 10-day injured list Tuesday with a strained right lat, retroactive to Aug. 1.

EDGE Analysis

Weems was effective in two relief innings Friday, allowing no runs on one hit and one walk while striking out two. However, he apparently suffered an injury around that time that will sideline him for several games. Right-hander James Kaprielian was promoted to the 30-man roster to take Weems' place. A timetable for Weems' return hasn't been announced.

Weems allowed two earned runs on four hits over three innings while recording three strikeouts in a loss to the Rockies on Tuesday.

EDGE Analysis

The converted backstop made his major-league debut, which came after a position switch four years ago and 10 separate minor-league stints spanning seven different seasons. Martin Gallegos of MLB.com reports Weems hit 97 mph with his fastball on a strikeout of Trevor Story to start his outing, and he was able to impressively settle down after allowing two runs in his first inning of work by retiring the final eight batters he faced. The hard-throwing right-hander threw 33 pitches overall and was also able to feature his changeup, slider and curve alongside the high-90s fastball.

Weems was informed Sunday that he'll be on the major-league roster for Opening Day, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

Weems was reported as a darkhorse candidate to make the roster early in camp, but he impressed enough to be rewarded with a spot in Oakland's bullpen to begin the season. The 27-year-old has had some control issues in the past but has been able to throw a fastball in the high-90s during camp. The right-hander hasn't pitched at the major-league level during his career, and it's a bit unlikely that he'll be used in many high-leverage situations early on.
