While the Philadelphia Phillies are taking on the Arizona Diamondbacks in a West Coast showdown, they have quietly made an intriguing signing in Major League Baseball.
Before getting into that, it’s important to note that the Phillies won the series opener on Monday night against the Diamondbacks and are now 4.0 games behind the Atlanta Braves for first place in the NL East.
So far, it’s been a pretty successful West Coast trip for Philly, and they will return home to face the aforementioned Atlanta Braves this weekend.

Phillies Signed Pitcher Sam Carlson on Tuesday

According to MLB.com’s transactions tracker, the Philadelphia Phillies have signed 27-year-old pitcher Sam Carlson to a minor-league contract. He has since been assigned to AA Reading.
Carlson had previously pitched in the Houston Astros organization, but he was released shortly after the MLB trade deadline, which was a bit of a surprise because Carlson does actually have solid statistics in the minors.
In 2026, with AAA Sugar Land (Astros), Sam Carlson boasted an ERA of 3.47 across 36.1 innings with 43 strikeouts.
He’s also been a member of the Los Angeles Dodgers, Milwaukee Brewers, and Seattle Mariners organizations.
