The A's show no urgency to name a closer — Alvarado and Hogan Harris continue splitting save chances with no hierarchy. Organizational ambiguity makes neither safe in standard formats. Monitor for any sign of consolidation.

Alvarado has 2 saves and 4 straight scoreless outings since his June 5 recall and is the closest Oakland has come to a defined closer all year. Mason Barnett (1.23 ERA, 33.3% K rate) remains in the mix, but Alvarado has the hot hand. Add in 14+ team leagues and watch the committee split — two or three more clean save conversions likely locks the role down.

Alvarado emerged as the A's primary closer after a June 5 recall and had four straight scoreless appearances, but has since allowed four home runs in his last four outings including a blown save against the Giants. Manager Mark Kotsay has not officially changed the job, but the homer rate is alarming and Oakland's committee history makes a role change possible. Hold cautiously; set a daily lineup reminder.

Scoreless in five of his last six appearances with an elite K rate, and his workload share is trending toward locked-in. Hogan Harris is still on the roster but Alvarado is clearly separating. Best upside play among all unstable closer situations — add now before the official designation arrives.

Scoreless in 5 of his last 6 appearances, posting a 0.36 WHIP with elite K numbers since emerging as Oakland's lead option. Hogan Harris is still in the picture but Alvarado's workload share is growing. Best upside add among committee closers in the short term.

Scoreless in 5 of his last 6 appearances, posting a 0.36 WHIP with 13 Ks and zero walks in that span. Hogan Harris is still technically the lead dog, but Alvarado is closing fast. Worth stashing in 14-team leagues.

Recalled June 5, Alvarado has two saves and four consecutive scoreless appearances — the cleanest recent run from any Oakland pitcher in high leverage. The A's have used six different pitchers for their 19 saves this season and have not named a closer, but Alvarado is the current front-runner. Viable in deep formats (14+ team) where any save opportunity has value; too volatile for standard leagues given the committee nature.
