Garrett Whitlock faced live hitters as part of his rehab work and could be activated in time for the Red Sox's upcoming series against the Yankees, MLB.com reported. The setup man has been working his way back, and the live batting practice session represents another step in that process.

What happened

Whitlock threw to hitters in a controlled setting, MLB.com reported. The Red Sox have not announced a formal activation date, but the report indicated he could rejoin the club when it opens a series at Yankee Stadium on Friday.

The timing would align with Boston's road trip. The Red Sox play Wednesday at Miami before heading to New York for a three-game set beginning August 28.

Why it matters

Whitlock has been a fixture in the back of Boston's bullpen when healthy, and his return would add a proven late-innings option as the club pushes toward October. The Red Sox are 78-65 and hold the second American League Wild Card spot, six games clear of the cut line. They trail the division leader by 7.5 games and are riding a three-game winning streak.

Setup relievers who can bridge to the closer are especially valuable in September, when rosters expand and the margin for error shrinks. Whitlock's ability to miss bats and limit hard contact has made him a high-leverage piece in years past, and his return would deepen a bullpen that will be tested down the stretch.

The Yankees series carries added weight. Boston faces New York six times in the final five weeks, and the head-to-head results could influence both the division race and the Wild Card picture. Whitlock's availability for those games would give the manager another option in tight spots.

Where the club stands

The Red Sox are 78-65, third in the AL East and 7.5 games behind the division leader. They rank second in the Wild Card standings, six games ahead of the cut line, and have won three straight.

Boston plays Wednesday at Miami, with Sonny Gray scheduled to face Ryan Gusto at loanDepot park. The club then travels to New York for a weekend series. Patrick Sandoval is slated to pitch Friday against Cam Schlittler, and Jake Bennett is lined up for Saturday opposite Carlos Rodón.

The schedule ahead is unforgiving. The bullpen will be asked to protect leads and keep close games within reach, and Whitlock's presence would give the club more flexibility in how it deploys its relievers.

What we don't know yet

The Red Sox have not announced a formal activation date. MLB.com reported that Whitlock could be ready for the Yankees series, but the club has not confirmed that timeline.

It is also unclear how Whitlock will be used when he returns. Setup men coming off extended absences sometimes ease back into high-leverage work, pitching in lower-stress situations before returning to their usual roles. The Red Sox may choose to bring him along gradually, or they may need him immediately depending on how the bullpen has fared in his absence.

The nature of Whitlock's injury and the length of his absence have not been detailed in the report. Rehab assignments for pitchers can last up to 30 days under league rules, but the report did not specify how long Whitlock has been out or how many rehab outings he has completed.

What to watch

Watch for an official roster move before Friday's game in New York. If Whitlock is activated, the Red Sox will need to clear a spot on the 26-man roster, and the corresponding move will offer a clue about how the club views its bullpen depth.

Watch also for how the club deploys Whitlock in his first few outings. The usage pattern will signal whether the right-hander is being eased back or thrust immediately into high-leverage situations.

The Yankees series itself will be worth monitoring. New York is a division rival, and the games carry playoff implications for both clubs. If Whitlock pitches, his performance will offer an early read on how effective he is after the layoff.

Finally, keep an eye on the Red Sox's bullpen usage over the next week. If other relievers are being stretched thin, Whitlock's return becomes even more urgent. If the group has been managing well, the club may have more room to bring him along slowly.

The Red Sox expanded their active roster to 28 players on September 1, per league rules, which will give them additional flexibility once Whitlock is cleared to return. That extra roster space means the club can carry more relievers without sacrificing bench depth, a luxury that becomes especially useful when managing workloads down the stretch.

Boston's bullpen construction will be tested repeatedly in the coming weeks. The club faces multiple series against Wild Card contenders, and the ability to deploy fresh arms in high-leverage spots could determine whether the Red Sox maintain their playoff position or slip back into the pack. Whitlock's return would address one of the few remaining questions about Boston's relief corps: whether it has enough depth to handle the September grind without overexposing any single arm.

The live batting practice session represents a standard progression for pitchers working their way back. Facing hitters in a controlled environment allows the medical and coaching staffs to evaluate command, velocity, and recovery between outings without the pressure of a game situation. The fact that Whitlock has reached this stage suggests the Red Sox believe he is close to full strength, though the club has not provided specifics about his readiness.

If Whitlock does rejoin the roster this weekend, his first appearance will be closely watched. The Yankees series offers a high-stakes environment for a return, but it also reflects the urgency of Boston's playoff push. The Red Sox are six games clear of the Wild Card cut line, a comfortable margin but not an insurmountable one with five weeks remaining. Every game matters, and the club appears willing to deploy Whitlock as soon as he is ready rather than wait for a lower-leverage opportunity.

The timing of his return also coincides with the final stretch of the season, when bullpen depth becomes paramount. Relievers who can handle multiple innings, pitch on short rest, or neutralize both left- and right-handed hitters become especially valuable. Whitlock has filled that role for Boston in the past, and his return would give the club another versatile piece to deploy in a variety of situations.

The Red Sox have not disclosed which hitters Whitlock faced or how many pitches he threw during the session. Those details would offer additional insight into his readiness, but the report focused on the broader timeline: that he could be activated in time for the Yankees series. The lack of specifics suggests the club is still evaluating his progress and has not committed to a firm date.

Boston's playoff hopes rest in part on the bullpen's ability to hold leads and keep the club competitive in close games. Whitlock's return would address that need, but only if he is fully healthy and able to pitch at the level he has shown in the past. The next few days will determine whether the Red Sox are ready to activate him or whether they need more time to ensure he is prepared for the demands of September baseball.
