Free-agent righty Greg Holland is arguably the highest-upside reliever left on the open market, and Jon Heyman of Fan Rag provides some notable updates on his situation. The 31-year-old is in a somewhat unusual spot as a free agent, in that he brings a sparkling track record but is also seeking to return from a long layoff due to Tommy John surgery.

Given his health situation and also the evident interest around the league, Holland seeks a two-year deal that would allow him to opt out after the first season, according to Heyman. That’s the same structure that Brian Wilson landed with the Dodgers before the 2014 season, though he had made it back to the hill late in the prior campaign.

In Holland’s case, there’s perhaps greater uncertainty, but also greater upside. He took a step back in his most recent action, in 2015, but that may well have been due to the elbow issues that led to his surgery. Over the prior four campaigns, Holland was one of the game’s very best relievers, as he compiled 256 1/3 innings of 1.86 ERA pitching with 12.6 K/9 against 3.2 BB/9.

There’s interest in Holland’s proposed two-year arrangement, per the report. Among the teams still pursuing him are the Dodgers, Nationals, Rockies, Brewers, Reds, and Rays. While the Cubs showed prior interest, it’s not clear whether they are still in. And the Royals have also indicated a desire to bring back their former closer, though it seems that the team’s payroll situation may not allow for a competitive bid.

That group of organizations would presumably offer Holland a variety of possible roles. The Nationals, Rockies, Brewers, Reds, and Royals (if they’re involved) could all promise him first dibs on closing roles, while the Dodgers and perhaps the Cubs are more likely to view the veteran as a setup man. Tampa Bay, perhaps, might be most interested in the event that it strikes a deal for incumbent closer Alex Colome. Whether and to what extent the chance to take hold of the ninth is an important factor in Holland’s decisionmaking is not immediately clear.
