In Week 12 of the fantasy baseball season, multi-position eligibility is a significant asset. Willi Castro of the Minnesota Twins, despite being slightly above the rostered threshold, has seen a surge in performance, making him a hot target. His eligibility at multiple positions increases his utility on fantasy rosters, especially with favorable matchups against the Reds.

Jose Caballero, playing for the Tampa Bay Rays, is another strong candidate, especially for managers seeking stolen bases. Despite a low batting average, his speed on the bases has made him a valuable asset lately.

In deeper leagues, keep an eye on Marcelo Mayer of the Boston Red Sox, who has shown promise since his promotion, and Hyeseong Kim of the Los Angeles Dodgers, who can contribute across various categories. Lastly, for the deepest leagues, Otto Lopez and DJ LeMahieu are worth considering as they display potential for significant contributions alongside favorable matchups.

Yandy Díaz was the hero for the Tampa Bay Rays as he hit a crucial two-run homer in the fifth inning that tied the game against the Miami Marlins. His double in the eighth set up the winning run, showcasing his ability to come through in clutch moments. The Rays triumphed 3-2, exemplifying their strong performance this season.

Drew Rasmussen’s streak of 23 scoreless innings ended as he allowed two runs, but he managed to pitch six innings with six hits. Tampa Bay now leads the majors with 90 steals, while Caballero’s thievery of third base in the eighth inning capped off his 21st of the season. The Rays continue to show their prowess on the base paths.

As fantasy baseball managers navigate the waiver wire in Week 10, several undervalued players have emerged as potential game-changers. Rhys Hoskins of the Milwaukee Brewers, with 47% rostered, has been a consistent performer, hitting .264 with nine homers and 35 RBIs while providing utility at first base. Jose Caballero from the Tampa Bay Rays, positioned as a leadoff hitter, is on track for over 50 steals this season and should be on every roster. Also on the rise is Brewers outfielder Sal Frelick, boasting a .393 batting average over the last week, with impressive speed and power metrics that make him a solid addition. Lourdes Gurriel Jr., quietly effective for the Arizona Diamondbacks, continues to deliver steady production, while Ryan O'Hearn of the Baltimore Orioles has become a reliable contributor amidst the team's injury struggles.

As we enter Week 10 of the 2025 MLB season, fantasy owners are looking for that edge to boost their rosters. This week, several under-the-radar players are making waves, particularly those under 40% rostered in Yahoo leagues. José Caballero is delivering impressive speed with 19 steals while Max Muncy heats up with five home runs over the last 15 games. Addison Barger’s hard-hit metrics are eye-catching, making him a sneaky add to your lineup. Cole Young's recent promotion showcases his potential for fantasy relevance after a stellar month in the minors. Ryan Weathers and Ryan Yarbrough are adroit pitchers to consider, offering solid strikeout potential. Meanwhile, Daniel Palencia has emerged as a reliable closer in Chicago.

Framber Valdez displayed remarkable resilience on the mound, bouncing back after giving up a home run to José Caballero on just the second pitch of the game. After a brief moment of frustration, Valdez transformed his performance, allowing only two hits and striking out nine over a complete game, contributing significantly to the Houston Astros' 2-1 victory over the Tampa Bay Rays.

Valdez’s efficiency was evident as he threw just 83 pitches, tying the record for fewest pitches in a nine-inning complete game for the Astros. His ability to induce groundballs and mix pitches effectively, particularly utilizing his sinker and curveball, kept the Rays' aggressive lineup at bay. Following the homer, he retired 24 of the next 25 batters he faced, showcasing his capability as a dominant starting pitcher.
