No Extension Talks Thus Far Between A’s, Mason Miller

The A’s have handed out two of the largest extensions in franchise history in recent months. They inked DH Brent Rooker to a five-year, $60MM guarantee in January. Earlier this week, they finalized a seven-year deal with outfielder Lawrence Butler that guarantees $65.5MM.

It’s possible that the Butler deal is the first of multiple A’s extensions in Spring Training. General manager David Forst told Evan Drellich of The Athletic a couple weeks ago that the team had opened talks with a few players. With Butler signed, closer Mason Miller should arguably be the team’s top extension candidate.

Miller told Foul Territory’s A.J. Pierzynski on Friday afternoon that he’s open to talks but hasn’t heard from the team about the possibility. The A’s control the hard-throwing reliever for another five seasons. Miller will qualify for early arbitration as a Super Two player next winter. He’d go through that process four times unless he signs an extension.

The A’s may not be eager to commit to a reliever, even one as dominant as Miller, whom they already have under control for a half-decade. There’s downside associated with the general volatility of relief pitching. Miller’s stuff is so exceptional that he’s a safer bet than almost any reliever to remain effective, but there’s more of a risk from a health perspective. He battled shoulder and elbow injuries and pitched fewer than 40 innings in the minor leagues.

Forearm tightness wiped out most of his ’23 season and was the main reason the A’s moved him out of the rotation during the 2023-24 offseason. Miller stayed healthy last year aside from an incident where he fractured the pinkie on his left (non-throwing) hand, which reportedly occurred when he hit a training table in frustration after a poor outing. That’s presumably not a concern moving forward, but as baseball’s hardest thrower, he certainly puts a lot of stress on his elbow and shoulder.

There have been a handful of extensions for relief pitchers in the 1-2 year service bucket. Miller would almost certainly look to set a new standard for that class if the A’s were interested in an extension. Emmanuel Clase’s five-year, $20MM guarantee is the current record. That deal, which was signed in April 2022, included a pair of $10MM club options to extend Cleveland’s control window by two seasons. Clase was coming an outstanding first full season, turning in a 1.29 ERA with 24 saves and 74 strikeouts in 69 2/3 innings. Miller struck out 104 hitters with a 2.49 earned run average over 65 frames last season. He went 28-31 in save chances.

Clase’s deal is a three-year old precedent that has turned into an extremely team-friendly contract. Clase also wasn’t on track to reach Super Two status, which meant he was two years from arbitration and had a much lower earning power through that process. Arbitration salaries escalate annually, and Super Two qualification sets a higher baseline for future raises. Clase didn’t have Miller’s injury history, but the Cleveland closer had served a performance-enhancing drug suspension in 2020 that added a different risk to his profile.
