As we enter Week 12 of the fantasy baseball season, astute managers have a chance to capitalize on undervalued assets. This week, five hitters shine: Willi Castro, Josh Smith, Miguel Vargas, Ryan McMahon, and Sal Frelick. Each of these players has shown potential for significant impact, making them worthy additions to your roster.

Willi Castro of the Minnesota Twins has returned from injury with impressive stats, batting .370 over his last seven games. Josh Smith's versatility and recent performance for the Texas Rangers have made him a key contributor. Meanwhile, Miguel Vargas of the Chicago White Sox is establishing himself as a reliable hitter, while Ryan McMahon is leveraging Coors Field's advantages. Finally, Sal Frelick continues to impress with his solid batting average and base-stealing skills for the Milwaukee Brewers. These players present various opportunities for fantasy managers looking to enhance their lineups as the summer months approach.

Richard Lovelady, once a reliever for the Toronto Blue Jays, has opted out of his minor-league contract with the Minnesota Twins. Despite a strong performance in Triple-A St. Paul, boasting a 1.31 ERA and six saves in 20.2 innings, Lovelady was not promoted to the majors. With a track record that includes stints with five MLB teams since 2019, Lovelady is now a free agent, likely to attract interest from teams searching for veteran pitching depth.

The Twins, currently fighting for an AL Wild Card spot at 36-36, may have missed an opportunity to bolster their bullpen with Lovelady's potential. As he embarks on another journey in free agency, teams might look to benefit from his experience and recent success.

The Cincinnati Reds faced a significant weather disruption during their game against the Minnesota Twins on June 18, with storms prompting a delay. The match, eagerly anticipated as Elly De La Cruz bobblehead night, was slated for a 7 p.m. start but could not commence on time due to a Severe Thunderstorm Warning issued for Great American Ball Park and nearby areas. As the clock ticked past 7 p.m., stadium officials announced that updates regarding the game status would be provided around 7:30 p.m.

Fans who were excited about the promotional event were left waiting as the grounds crew swiftly covered the infield to protect it from impending rain. This delay highlights the unpredictable nature of baseball, where Mother Nature can sometimes intervene, forcing teams and fans alike to exercise patience.

Aaron Sabato, the former first-round pick of the Minnesota Twins, is on the verge of reaching the major leagues after being promoted to Class AAA with the St. Paul Saints. The 26-year-old first baseman has been working through injuries and a high strikeout rate since being drafted 27th overall in 2020. With a recent batting average of .305, nine home runs, and a reduced strikeout rate at Wichita, Sabato is showing promise and has gained attention as a legitimate prospect.

While his early career has been hampered by injuries and challenges at Class AA, this promotion signifies a turning point. Manager Toby Gardenhire and player development director Drew MacPhail have praised Sabato's renewed swing and readiness for the next level. As the Twins struggle, Sabato's performance could provide the team with a much-needed boost as they look to integrate young talent into the roster.

Framber Valdez is scheduled to start against the Oakland Athletics, a matchup he has historically excelled in, which should be a consideration for MLB DFS players crafting their lineups. With a career ERA of 2.64 against the A's and having allowed only one earned run in 13.1 innings last season, Valdez is a viable option for starting pitcher on platforms like FanDuel and DraftKings. While he won't be a budget pick, his strong past performance against Oakland makes him a formidable choice for daily fantasy lineups.

In addition to Valdez, Astros second baseman/outfielder Jose Altuve is also highly recommended, especially given his history against Athletics starter Luis Severino, with a batting average of .275 and a home run in 40 at-bats against him. Severino's struggles this June, marked by a 6.63 ERA, further enhance Altuve's appeal as a solid value pick for DFS players. Similarly, Carlos Correa of the Twins presents a favorable matchup against left-handed pitcher Nick Lodolo, having hit .269 with a significantly elevated OPS against lefties this season. As insights from expert Mike McClure suggest, these players could be key to a successful DFS strategy on June 18.
