Hierarchical Update – Philadelphia Phillies

Understanding Phillies manager Rob Thomson prefers not to label a reliever the closer while operating his “floating closer” concept; they are deployed in matchup-based circumstances, depending on the situation and lineup. Even though Jordan Romano recorded seven saves in 12 appearances between April 27 and May 29, he has been appearing in lower-leverage outings since allowing a run in three consecutive games at the onset of June. His struggles opened the door for larger leverage roles by his teammates.

Last night, Orion Kerkering retired the side and recorded a strikeout, throwing 12 pitches (75 Strike%) with one whiff at the bottom of the ninth in Miami, preserving a three-run lead for his first career save.

This extended his scoreless streak to six, during which he posted this save and a win with a 0.877 WHIP while striking out seven against two walks (17.4 K-BB%) across 5.2 innings. Matt Strahm allowed two hits and an earned run on a sacrifice fly, getting credit for his ninth hold. Jordan Romano tossed a scoreless seventh, hitting a batter and recording two strikeouts while securing his sixth hold. Taijuan Walker notched his first hold, retiring the side and striking out one in the sixth.

From a fantasy lens, Kerkering has moved up Rob Thomson’s trust tree. It’s tough designating anyone as the closer in this leverage ladder, but if Kerkering is on waivers, it’s time to make the move and hope he emerges as the preferred option. This remains listed as a shared situation, and we await how it will evolve.
