Ruiz, 26, was the Athletics’ primary center fielder in 2023 and swiped a gaudy 67 bases that season but did so while batting only .254/.309/.345 in 132 games (497 plate appearances). Though he was one of several key players acquired in the Athletics’ slate of rebuild-focused trades — regrettably coming over in a three-way deal that sent star catcher William Contreras, whom the A’s could’ve kept, to the Brewers — Ruiz has fallen a ways down the team’s depth chart since that original acquisition.

Injury played a role in his drop down the pecking order, as he missed the bulk of the 2024 campaign with a wrist strain. Ruiz logged 29 games and 65 plate appearances in the majors and delivered only a feeble .200/.270/.382 output at the plate. He hit .345/.425/.596 in 73 minor league plate appearances last year, but he’s long had eye-catching numbers in the upper minors that haven’t carried over to MLB, where he’s a .243/.297/.343 hitter in 598 plate appearances. Ruiz didn’t do himself any favors this spring, hitting .121/.171/.152 in 35 trips to the plate during Cactus League play.

The A’s locked Lawrence Butler up on a long-term extension and saw JJ Bleday turn in a breakout performance at the plate last season. That leaves two of their three outfield spots spoken for in the long-term. Bleday is miscast as a center fielder, so perhaps there’s room for Ruiz to work his way back into that role, but prospects like Colby Thomas, Denzel Clarke and Henry Bolte are all on the cusp of MLB readiness as well. At least for the early stages of the 2025 campaign, it looks like the A’s will go with a left field platoon of Seth Brown and Miguel Andujar.

In the rotation, Ginn heads back to Triple-A on the heels of a tough spring. The righty’s final outing was excellent — four innings of one-run ball with seven punchouts — but he still served up 13 runs (11 earned) in 13 innings while walking 12.5% of his opponents. The 25-year-old is a former second-round pick whom the A’s acquired in the trade sending Chris Bassitt to the Mets. He was hit relatively hard between Double-A and Triple-A last year but turned in a decent blend of strikeout, walk and ground-ball rates (21.2%, 8.8% and 54.1%, respectively). He held his own with a 4.24 ERA in his first 34 MLB frames last summer as well.

With Ginn being sent out, it increasingly appears as though the Athletics’ season-opening rotation will include Luis Severino, Jeffrey Springs, JP Sears, Osvaldo Bido and Mitch Spence. A late injury could always change that, and the A’s still have one possible rotation alternative in camp in the form of Joey Estes, who’s had a decent Cactus League run this spring.

Hernaiz, acquired in the trade of Cole Irvin to Baltimore, became a long shot for the roster after the A’s signed both Gio Urshela and Luis Urias to major league contracts this winter. Jacob Wilson and Zack Gelof are lined up in the middle infield, while Urias and Urshela can handle third base and move around to multiple infield positions. Hernaiz hit well in Triple-A last year (.331/.376/.493) but mustered only a .192/.261/.242 line in his first 135 MLB plate appearances. His spring output wasn’t much more encouraging — .194/.302/.306 in 43 plate appearances — so he’ll had back to the minors for more work.

Holman will be making his Major League debut whenever he makes his first official appearance for the A’s.  A sixth-round pick in the 2021 draft, Holman has worked exclusively as a reliever since he was promoted to Double-A in 2023, and his results this season have been spectacular.  The righty has a tiny 0.55 ERA over 48 2/3 combined innings at Double-A (19 1/3 IP) and Triple-A (29 1/3 IP), along with a strong 29% strikeout rate and a more modest 11.83% walk rate.  It should be noted that Holman has received a lot of batted-ball luck in the form of a .174 BABIP against Triple-A competition, but allowing just one homers in 29 1/3 frames of Pacific Coast League action is quite impressive.

MLB Pipeline rates Holman as the 21st-best prospect in Oakland’s farm system, and he received a 60-grade on his 95mph fastball.  Beyond that top offering, Holman also has a decent slider and a rather lightly-used splitter.  It makes for a pretty solid arsenal for a reliever, and Pipeline’s scouting report observes that “much of Holman’s step forward this season has come simply as a result of being healthy and getting regular reps,” following two seasons of elbow and shoulder problems.

There’s plenty of intrigue in Holman’s arsenal, and the 24-year-old should get opportunities for an Athletics team that continues to evaluate young talent as part of its rebuild.  Mason Miller has deservedly drawn most of the headlines, but Oakland’s bullpen has been pretty decent as a whole this season, and Holman will become the latest rookie arm to try and earn higher-leverage work.
