On Tuesday morning, the Red Sox signed a free agent for the second time this winter, agreeing to terms with veteran reliever Aroldis Chapman on a one-year, $10.75 million contract.

The signing gives the Red Sox a power lefty for the bullpen, something they had been looking for. But the deal raises almost as many questions as it answers.

Here are five:

1. Was Chapman signed to be the team’s closer?

Chapman ranks third among active pitchers with 335 career saves, trailing only Kenley Jansen (447), who played the closer role the past two seasons, and Craig Kimbrel (440), who pitched for the Reds from 2016-18 Sox played. Chapman also had 14 saves for the Pittsburgh Pirates last year.

But he took on the closer’s role more or less accidentally after the Pirates’ usual closer, David Bednar, struggled badly last year. In fact, Chapman hasn’t been his team’s primary ninth-inning option since 2021, when he saved 30 games in his second stint with the Yankees.

The Red Sox have other options for the ninth inning, led by Liam Hendriks, a three-time All-Star who recorded a combined 75 saves in 2021-22. But Hendriks is also coming off Tommy John surgery and has thrown just five innings since 2022, and there’s little expectation of him heading into spring training.

2. Does this mean the Red Sox are out? Free agent Tanner Scott?

That is unknown. Scott is the prize of this winter’s free-agent reliever class, having established himself as one of the game’s best closers over the past two seasons (2.04 ERA, 36 saves in 146 games). He would receive a multi-year contract with an AAV of $14-15 million, and since he was traded from Miami to San Diego at the deadline, there is no draft pick compensation attached to him.

But at some point the Red Sox, known to be finalists for outfielder Juan Soto and looking for a top rotation starter, will have to prioritize their offseason spending. And since the Sox have already spent nearly $11 million on Chapman, they may need to put their money elsewhere.

3. What impact will Chapman have on the Boston bullpen?

Regardless of the role, Chapman gives the Red Sox what manager Alex Cora has been asking for for some time – another late-inning reliever with swing-and-miss stuff.

Chapman’s fastball still reaches nearly 100 miles per hour and he averaged 14.3 strikeouts per nine innings with a 37 percent strikeout rate. He joins Justin Slaten, Luis Guerrero, Hendriks and fellow newcomer Justin Wilson as late-inning options who can miss bats.

The Sox still have options. They could pursue Scott or another confidant via trade or free agency. Or they could have a competition between Chapman, Hendriks and others in the spring.

Most importantly, his presence means that the Red Sox have multiple power arm options for the first time in a while, which in turn allows players like Zack Kelly, Josh Winckowski, Brennan Bernardino, Cam Booser and Garrett Whitlock to contribute in the sixth and third seventh inning.

4. Can Chapman throw enough punches to be effective?

As always, this question remains for the experienced Cuban. His 5.7 walks per nine innings, coupled with a 14.7 percent walk rate, are menacing. Walks have always been a part of Chapman’s game – that’s what teams sign up for, taking advantage of his ability to elicit sniffs in the hope that the latter will be far more numerous than the former.

Normally a team would hope that a mechanical adjustment or tweak could improve its control, but after 15 seasons in the major leagues, Chapman is who he is, and no matter how dedicated and effective pitching coach Andrew Bailey is, he will probably won’t change much.

For the most part, Chapman has managed to limit mistakes. His career home run rate of 1.6 percent is well below the MLB average (2.9 percent), suggesting he can usually minimize the damage when allowing baserunners.

5. Did the Red Sox investigate the details behind Chapman’s arrest in 2015?

In 2015, Chapman was suspended by Major League Baseball for 30 games before the start of the 2016 season, stemming from an incident during the previous offseason. Chapman fired eight shots in the garage near his home and his girlfriend initially claimed he choked her during an argument. Officials in Florida declined to charge Chapman with a crime, but the MLB cited its own discipline.

In the past, the Red Sox have stated that they have zero tolerance for perpetrators of domestic violence and have strongly condemned Steven Wright and others accused over the years.

Zack Scott, who served in various roles in the Red Sox front office between 2015 and 2020, revealed that the circumstances surrounding his arrest were being carefully examined. Chapman was traded to the New York Yankees later that winter.

Publicly, the Red Sox have not yet commented on or confirmed the signing, so it is unclear what additional vetting they may have conducted. No doubt this will be a point of interest when they announce the signing.
