The Phillies’ bullpen needs are hard to miss, and one free-agent name on Jim Bowden’s board fits the conversation cleanly: Jonathan Loáisiga.
Bowden of The Athletic placed the right-handed reliever at No. 42 on his list of the Top 40 MLB free agents, with a few more names grouped as the “best of the rest.” He also identified the Phillies and Diamondbacks as possible landing spots for Loáisiga this winter.
That makes sense for Philadelphia, which got uneven relief work at the wrong time. The club’s 4.43 bullpen ERA ranked 20th in the big leagues, and the unit’s September collapse was especially damaging, as the Phillies bullpen posted a 5.79 ERA that month. The struggles carried straight into October, when Philadelphia’s relievers gave up seven earned runs in 12.2 innings during the National League Wild Card Series against the Atlanta Braves.
Adding more depth to the bullpen, particularly a lefty, is part of the puzzle for a team trying to push deeper into the postseason.
Loáisiga just finished the 2026 season with the Arizona Diamondbacks and gave them a strong year. He worked to a 2.42 ERA with 48 strikeouts, the second-most he has ever had in a season, while setting a career high with 67 appearances and 67 innings out of the bullpen.
He also posted a 1.03 WHIP, a 172 ERA+ and a 2.88 FIP. Perhaps just as important, he stayed healthy for Arizona, which matters as he heads into free agency.
Before that, Loáisiga spent eight seasons with the New York Yankees from 2018 to 2025. His best run in pinstripes came in 2021, when he logged a 2.17 ERA in 70.2 innings and finished 9-4. Across his Yankees tenure, he put up a 4.2 WAR, a 3.54 ERA in 249.1 innings and 232 strikeouts.
Injuries made the final stretch of his time in New York difficult, especially from 2023 to 2025, when staying on the mound became a challenge.
Philadelphia was still in the race until the end of the regular season in 2026, and shoring up the bullpen could be one way to help the team get to the postseason earlier and make that next step once it gets there.

Phillies Are Quietly Building Infield Depth For A Bigger Roster Squeeze
The Phillies added a pair of infielders off waivers from the Giants, claiming Brett Harris and Shay Whitcomb as part of a quiet push to strengthen organizational depth. It is the kind of move that does not change the top of the roster right away, but it does matter for a team that is always balancing injuries, rest days and the need to keep options available for the long season.
Harris and Whitcomb both bring strong Triple-A rsums, even if neither has much major league experience yet. The roster wrinkle is different for each player: Harris has no minor league options left, while Whitcomb does, which could make it easier for the Phillies to keep him around as the season moves forward and the infield picture gets tighter.

Phillies Fans Just Got A Revealing Look At Don Mattinglys Setup
Don Mattingly has been around long enough to know that baseball families can be complicated, but his latest stop in Philadelphia comes with a twist even he seems to enjoy. The Phillies manager recently talked about what it is like working under his son, Preston Mattingly, the clubs vice president and general manager, and described the arrangement as fun while also saying he has picked up on the different ways Preston sees the game.
For a Phillies team that just finished an 88-win season, the timing matters. The front office is weighing roster changes, MLB labor talks are still hanging over the sport, and Bryce Harpers future status remains uncertain, so the organization is entering a stretch where every layer of decision-making feels connected. In that context, the Mattingly setup offers a rare glimpse into how the Phillies are trying to blend familiarity, communication and a fresh perspective as the offseason begins to take shape.

Phillies Prospects Are Flashing Big Upside But One Question Remains
Baseball Americas latest look at the Phillies system offered plenty for the front office and fan base to feel good about, with several names drawing attention for different reasons. Tyler Spangler, Will Gasparino, Bryan Rincon and Francisco Renteria all surfaced as prospects with real upside, while pitchers Gage Wood and Wen-Hui Pan added more depth to a farm system that appears to be building across multiple areas. Even the defensive side of the ledger has some pop, with Rincon and Nathan Humphries standing out for their work in the field.
What makes the group interesting is how varied the skill sets are, from toolsy position players to arms with room to grow. The bigger question now is how all that promise translates into actual major league help, because a system can look encouraging on paper and still leave one important issue hanging until the prospects start turning potential into production.
