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.

The Chicago Cubs are dominating the NL standings with a balanced team that combines solid fundamentals with spectacular talent, primarily highlighted by the exceptional play of Pete Crow-Armstrong. The Cubs, currently boasting a 39-23 record, excel in critical areas such as defense, baserunning, and limiting strikeouts. Crow-Armstrong, a candidate for NL MVP, showcased his all-around skill set by influencing games both with his speed and power, including a recent impressive home run against the Nationals.

His ability to perform under pressure has made him a standout player, while his teammates, including Kyle Tucker and Dansby Swanson, contribute to a cohesive unit focused on team success. The Cubs' approach to the game emphasizes smart play and accountability, resulting in optimal performance on the field. As the season progresses, the Cubs appear to be a team of destiny, blending youthful exuberance with veteran experience.

The Chicago Cubs enter a crucial nine-game road trip tied for the best record in the National League with the New York Mets. Following a strong 5-1 homestand, the Cubs now face tough matchups against the Washington Nationals, Detroit Tigers, and Philadelphia Phillies. Key highlights include Daniel Palencia stepping up as an unofficial closer, achieving five consecutive saves, while Ryan Pressly has regained confidence with nine scoreless innings in his last outings. New acquisition Génesis Cabrera also adds depth in the bullpen, showcasing his potential in late-game situations. Rookie Pete Crow-Armstrong showed promise with two walks in a game, pointing toward his evolving discipline at the plate. Finally, Dansby Swanson's wig giveaway was a hit, earning fan engagement and showcasing the fun side of the franchise.

Memorial Day brings a packed MLB schedule with exciting home run prop bets. Having had a successful week, with a +4.15 unit gain, today features bets on Dansby Swanson, Jordan Beck, Miguel Vargas, and Kody Clemens. Swanson stands out against Rockies’ rookie Carson Palmquist, who has struggled against right-handed hitters. Beck capitalizes on Jameson Taillon’s reverse splits, while Vargas has been hot against righties. Lastly, Clemens is poised to take advantage of favorable hitting conditions against Zack Littell.

Swanson’s power against Palmquist's four-seamer and sinker is backed by impressive stats. Beck, despite not hitting a home run recently, showcases promising contact rates, particularly against pitches Taillon struggles with. Vargas' recent surge against right-handers suggests his potential for a home run, while Clemens is well-positioned in a favorable park to launch one. Always remember to manage your bankroll wisely when placing prop bets.

The upcoming week of May 26 - June 1, 2025, is set to spotlight several intriguing players in fantasy baseball. Key names include Marcelo Mayer, who is stepping up for the Boston Red Sox due to Alex Bregman’s injury. After a shaky debut, Mayer is showing promise with a double in his second game. Lawrence Butler of the Athletics is on the cusp of a breakout, having logged extra-base hits in six straight games, despite a tough matchup against Hunter Brown.

Brandon Lowe is heating up for the Tampa Bay Rays, riding an eight-game hitting streak which has boosted his average significantly. Kody Clemens of the Twins is also making noise with a six-game hitting streak, showcasing his power potential. Dansby Swanson is maintaining an impressive on-base streak, contributing significantly to the Cubs’ offense. Finally, Colton Cowser is back from injury for the Orioles, looking to provide a jolt to their lineup.
