Phillies lean on new late-inning options as Alex McFarlane and Orion Kerkering become high-leverage choices

The Phillies’ bullpen picture has tightened at exactly the wrong time. In the high-leverage, tie-game and one-run situations that define September baseball, Philadelphia has reportedly faced moments when neither Jonathan Bowlan nor Jhoan Duran was available for the kinds of roles the club values most. Yahoo Sports’ late-inning trust framing centers on who the Phillies can count on right now, specifically naming Alex McFarlane and Orion Kerkering as the two arms fans and the coaching staff are focusing on during those pivotal sequences.

The context behind the urgency is that Philadelphia has had to adapt following the season-ending absence of Brad Keller, a change that has forced the organization to shuffle its preferred setup-and-close pathways. Yahoo Sports describes Bowlan and Duran as pitchers the Phillies want to use in the eighth and ninth innings in games that are tied or the Phillies are protecting a lead, and it notes those options have not been there in the same way in recent days.

That leaves the manager with a smaller margin for error when the game reaches the back end. In these situations, a bullpen arm is not simply throwing innings, it is executing a defined job. McFarlane and Kerkering are effectively being measured against what Philadelphia’s late-inning plan is supposed to accomplish: preserve leverage, prevent the opponent from flipping momentum, and keep the offense close enough to finish the job.

The difference between the two is not just stylistic, it is operational. A bullpen’s late-inning reliability is shaped by availability, recent usage, and how the staff pairs specific pitchers with matchups in the seventh-, eighth-, and ninth-inning windows. When one or two intended pieces are unavailable, the remaining options become the only bridge to the final outs, and the staff must commit to that bridge sooner than it would in a steadier week.

The Phillies are not operating in a vacuum. Late-inning baseball is where teams separate themselves, especially when games turn quickly and the margin for relief mistakes shrinks. A manager’s “trust” is built on repeated execution under pressure, so the immediate question is whether McFarlane or Kerkering can consistently deliver the outcomes Philadelphia needs when the game is tight and the platoon matchups are unforgiving.

What to watch next is how the Phillies decide between McFarlane and Kerkering in similar game states, particularly in consecutive appearances. If the coaching staff repeatedly selects one pitcher for eighth-innings with leads and ties, it will suggest the trust is moving beyond a one-off need. If usage stays more mixed, it may indicate the Phillies are still sorting out best-fit leverage roles as availability constraints continue to shape the late-inning rotation.
