A’s sign one-time All-Star OF/DH to five-year extension

The righty-swinging Rooker has become not only one of the most successful waiver claims in recent memory but one of baseball’s best hitters. He popped 30 home runs in 526 plate appearances to earn an All-Star selection in 2023. While he was snubbed from the Midsummer Classic last season, Rooker took another major step forward. He connected on 39 homers, 26 doubles and a pair of triples with a massive .293/.365/.562 batting line across 614 plate appearances.

Rooker finished tied for fifth in home runs. Only Aaron Judge, Shohei Ohtani, Anthony Santander and Juan Soto hit more. Among hitters with at least 500 PAs, Rooker ranked in the top 20 in all three slash stats. He finished sixth in slugging.

It’s now two seasons of borderline elite offensive production. Rooker has a .272/.348/.528 slash through more than 1100 plate appearances in an A’s uniform. He’s in the top 15 in slugging percentage and ranks ninth in homers since the start of the ’23 campaign.

There is a decent amount of swing-and-miss to his game, as Rooker has fanned in more than 30% of his plate appearances with the A’s. Last year’s production was driven in part by a .362 average on balls in play that’ll be difficult to maintain. Rooker makes a ton of hard contact, though, so he’s probably in line for a modest BABIP regression rather than a huge drop-off.

The ball-in-play normalization happened at the end of last season. Rooker carried an unsustainable .390 BABIP into the All-Star Break. That dropped to .333 in the second half. To his credit, Rooker compensated by cutting his strikeout rate to a much more manageable 24.1% during that stretch. It remains to be seen whether he’ll maintain that level of contact, but it’s an encouraging development that presumably affirmed the front office’s confidence in his hitting acumen.

Even if he doesn’t hit .290 while pushing 40 home runs on an annual basis, Rooker should remain an impact bat. The A’s have made clear they envisioned him as the long-term anchor of their lineup. The team reportedly took him off the market in advance of last summer’s trade deadline. They had no interest in allowing trade rumors to rekindle during the offseason. GM David Forst declared within a week of the offseason beginning that the A’s weren’t dealing Rooker. They’re doubling down by committing to him through at least the 2029 season.

Rooker surpassed three years of major league service last season. He was entering his first of three arbitration seasons. MLBTR contributor Matt Swartz had projected a $5.1M salary for next year. While the specific breakdown is unknown, Rooker will reportedly receive $30M over what would have been his arbitration window. That leaves an average of $15M annually for the two free agent seasons. It’s not quite a front-loaded contract, but it appears Rooker will make a little more in the next couple years than he would have had he gone through the arbitration process.

The team makes that tradeoff for the chance to keep him at below-market rates during the 2028-29 seasons — which are scheduled to be their first two years in Las Vegas. The A’s didn’t have any money guaranteed beyond 2027. Severino and recent trade pickup Jeffrey Springs were their only players signed past next season.

The A’s revenue sharing status has been a significant storyline this offseason. Evan Drellich and Ken Rosenthal of the Athletic reported that the team could need to push its competitive balance tax payroll to roughly $105M to avoid an MLBPA grievance. Teams are required to spend revenue sharing money on the on-field product.

Extending Rooker will push their tax number up, though it’s not by a huge amount. The contract comes with a $12M average annual value. The AAV is the number used for tax purposes, so it wouldn’t matter how the salaries are distributed. Rooker had already been expected to make around $5M next season. This adds roughly $7M to the team’s tax number, which will check in around $97M (as calculated by RosterResource).

The tax number isn’t finalized until the end of the year, so the remainder of the A’s offseason and in-season activity can push that further. Tax considerations are relevant but are far from the only reason for the A’s to make this deal. If they were solely concerned about pushing next season’s CBT number, they could have signed a handful of mid-tier free agents to one-year contracts.

Rooker turned 30 in November. A five-year commitment runs through his age-34 season. There’s some risk in a five-year deal for a player in his 30s who doesn’t provide much defensive value. Yet if Rooker continues hitting at anywhere near this level, his arbitration price tag would have climbed quickly anyhow. He could have put himself in position for an AAV in the $20M-25M range once he hit free agency, a number that the A’s may have been disinclined to match.

At the same time, it’s easy to see the appeal for Rooker of locking in the security. It wasn’t that long ago that he looked like a fringe roster player. He wouldn’t have gotten to free agency until his age-33 season, when a three- or four-year deal might’ve been the ceiling. Sacrificing a little bit of long-term earning upside to avoid injury risk over the next couple seasons is understandable.

This should also solidify Rooker’s spot in what looks to be an up-and-coming A’s lineup. Lawrence Butler, Jacob Wilson, Tyler Soderstrom, Shea Langeliers, JJ Bleday and rebound candidate Zack Gelof have promise as an offensive core. Last summer’s fourth overall pick Nick Kurtz could move quickly as a polished college hitter. The A’s still need a lot to break right to contend in 2025, but things are starting to come into focus. Soderstrom and Kurtz fit best at first base, so perhaps there’ll be a logjam down the line with Rooker locked in at designated hitter. That’d be a good problem to have if both young first basemen reach their offensive ceilings and Rooker continues to hit at an All-Star level.
