NL East Notes: Montas, Blackburn, Manaea, Nola, Finnegan

Frankie Montas saw his first proper game action of the 2025 season on Saturday, when the right-hander tossed 37 pitches over 1 1/3 innings for high-A Brooklyn in the first game of a minor league rehab assignment.  Montas signed a two-year, $34MM free agent deal with the Mets this past winter, but was immediately sidelined at the start of Spring Training by a significant lat strain.  Saturday’s game officially started the 30-day clock on Montas’ rehab assignment, and he’ll naturally need to further build up his arm strength over multiple outings before he is ready to be activated from the 60-day injured list.

Paul Blackburn should beat Montas back to the active roster, as MLB.com’s Jeffrey Lutz writes that the plan is for Blackburn to make his seventh and final minor league rehab outing before joining the Mets at some point in June.  Blackburn has missed the entire big league season due to right knee inflammation, while Sean Manaea has also yet to pitch due to an oblique strain.  Manaea is throwing off a mound, and Jon Heyman of the New York Post writes that Manaea’s projected timeline is about two weeks behind Montas.  Despite all of these pitching injuries, even the makeshift version of the Mets’ rotation has posted tremendous results this season, giving the club a potential arms surplus to address if and when everyone is healthy.

• The Phillies are another club relatively deep in starting pitching options, though they may be without Aaron Nola for longer a 15-day minimum stint on the injured list.  Manager Rob Thomson told Lochlahn March of the Philadelphia Inquirer and other reporters that Nola’s sprained ankle is still feeling sore, which scrapped plans for Nola to begin throwing off a mound this weekend.  Nola’s IL placement began on May 15, and while Thomson didn’t this continued discomfort as any sort of big setback, he hinted that Nola might need to face some live batters (whether in the form of a live batting practice or a minor league rehab start) before being activated.
• Nationals closer Kyle Finnegan is dealing with some shoulder fatigue, though manager Davey Martinez told MASNsports.com’s Mark Zuckerman that tests didn’t reveal any structural problems.  Finnegan hasn’t pitched in either of Washington’s last two games, but figures he can avoid the IL with another day or two of rest.  Finnegan has a 2.41 ERA over 18 2/3 innings this season, and figures to be a sought-after pitcher at the trade deadline if the Nationals can’t get into contention.  The reliever’s secondary numbers (such as a 3.69 SIERA and slightly below-average strikeout and walk rates) are less impressive, but Finnegan has a 48.1% grounder rate and has done a solid job of inducing soft contact.
