In the fast-paced world of dynasty fantasy baseball, Week 15 of the 2025 season brings notable call-ups and potential breakout candidates. Colby Thomas made his debut with the Oakland Athletics after an impressive Triple-A stint, although current usage as a pinch hitter raises concerns about his immediate fantasy impact. Conversely, Colson Montgomery's recent performance with the Chicago White Sox shows promise, highlighting his potential as a solid addition for fantasy leagues despite initial struggles. Montgomery's recent improvements suggest a bounce-back is in motion. Meanwhile, Anthony Seigler joins the Milwaukee Brewers after a strong minor-league showing, showcasing versatility that could enhance his playing time.

Looking at the league's dynamics, players like Jacob Wilson and Alex Bregman may face negative regression based on their metrics, while Andrew Vaughn and Juan Soto could see upside based on favorable expected stats. Investors in dynasty leagues should consider these trends when contemplating trades as the season progresses.

The Baltimore Orioles have made a strategic move by acquiring Alex Jackson from the New York Yankees after their starting catcher, Gary Sánchez, landed on the injured list due to a right knee sprain. This injury marks Sánchez as the fourth catcher currently sidelined for the Orioles, who are already dealing with a significant number of players on the IL. Interim manager Tony Mansolino is optimistic about the new catching duo consisting of Jackson and Jacob Stallings, who recently joined the roster from Triple-A Norfolk.

Jackson, a 29-year-old backstop, has previous MLB experience with teams like Atlanta, Miami, and Milwaukee. He comes off a season with Triple-A Scranton/Wilkes-Barre, where he hit .226 with 10 home runs. Mansolino's confidence in Jackson's ability to quickly adapt to the major leagues will be crucial as the Orioles look to maintain their competitive edge amid numerous injuries.

As the MLB season approaches the All-Star break, savvy fantasy baseball players are looking to bolster their rosters with under-the-radar hitters. This week, several players have emerged as strong candidates for waivers, offering potential boosts in critical categories like runs, home runs, RBIs, stolen bases, and batting average.

Josh Smith of the Texas Rangers, rostered in just 36% of leagues, continues to shine at the plate, boasting a .311 average with three home runs and 18 runs scored recently. Caleb Durbin of the Brewers is another name to watch, hitting .296 with three homers and 18 runs in June. Meanwhile, Ramon Laureano has returned to form with the Orioles, hitting .312 with four home runs and leading in runs scored.

For power hitters, Kyle Stowers of the Marlins is on the rise, hitting three home runs in the last week of June, while Gary Sanchez is making a significant impact for the Orioles as well, providing solid numbers despite limited playing time. Lastly, Otto Lopez is leading the NL in RBIs this month, making him a must-roster player. As the season progresses, these players could be the difference-makers for fantasy teams.

The Texas Rangers faced a significant injury setback as Cody Bradford was ruled out for the season, necessitating elbow surgery. Meanwhile, relief pitcher Marc Church has been placed on the IL due to elbow inflammation, raising concerns after a rocky return from a previous injury. Church struggled in his last outing, failing to retire any batters against the Oklahoma City Dodgers. On a more positive note, catcher Malcolm Moore has been activated after recovering from a fractured finger.

Bradford's surgery is being overseen by Dr. Keith Meister, a respected figure in the field of elbow injuries. Church, who impressed during spring training and made the opening day roster, now faces an uncertain path as he seeks to return to form. Moore's return from the IL provides a much-needed boost to the Rangers' catching depth, as they look to navigate through this challenging stretch of the season.

As the MLB season progresses, streaming options on the waiver wire become essential for fantasy baseball managers looking to bolster their rotation. Here are ten pitchers, all rostered in under 80% of CBS Sports leagues, to consider for Week 12 (June 9-15). These pitchers could provide significant value, especially in two-start scenarios.

Eury Pérez returns from Tommy John surgery, facing the Pirates and Nationals in his first week back, presenting solid matchup potential. Jack Leiter, contingent upon the Rangers' rotation adjustments, offers a strong ERA but faces uncertainty in his second start.

Griffin Canning has been effective lately, although his high walk rate raises concerns. Zebby Matthews is gaining trust within the Twins' rotation and faces manageable lineups. Meanwhile, Hayden Birdsong’s performances suggest he could thrive at Coors Field against a struggling Rockies offense.

Jeffrey Springs and Luis Ortiz also make the list, each with favorable matchups that could lead to quality starts. Mitch Keller's recent struggles somewhat mitigate his streaming appeal, but he remains a candidate. Finally, Clarke Schmidt benefits from two starts, one against a weak Royals lineup. Each of these pitchers presents varying levels of risk and upside for managers looking to maximize their pitching stats this week.
