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.

Josh Smith's week as the reigning AL Player of the Week began unexpectedly on the bench due to left hamstring tightness. Manager Bruce Bochy assured that Smith wouldn't require an IL stint but noted he is day-to-day. Smith's impressive week prior included a staggering .423 batting average with a 1.269 OPS, although he felt discomfort during a recent game, leading to a pinch-hit substitution.

With Smith sidelined, Evan Carter stepped into the leadoff spot, marking just his second time hitting in that position for the Rangers. Carter has also been performing exceptionally, boasting an even higher slash line of .444/.545/.889 before the switch. This reshuffling could significantly impact the Rangers' lineup strategy moving forward as they look to maintain their momentum.

Josh Smith has solidified his place as a fan favorite for the Texas Rangers during his standout 2024 season, marked by accolades like the AL Player of the Week and a Silver Slugger Award. Drafted by the Yankees and later traded to Texas in a deal involving Joey Gallo, Smith's contributions have been pivotal, especially with increased playing time due to injuries on the team. His impressive performance includes 13 home runs and 62 RBIs, showcasing his potential to be an everyday starter.

Smith's versatility allows him to play multiple positions, which he has demonstrated consistently since his debut. Alongside his on-field success, he and his wife Claire maintain an engaging social media presence, offering fans an inside look at their lives. The couple's YouTube channel, which showcased their journey through the minor leagues, reflects their commitment to connecting with the fanbase.

As the Atlanta Braves gear up for a three-game series against the New York Mets, Ronald Acuña Jr. has been making headlines for his outstanding performance. Over the last week, Acuña has showcased his elite talent, hitting .619 with three home runs and six RBIs, helping the Braves recover from an early June slump. His accomplishments earned him the National League Player of the Week award, a recognition he shares with Josh Smith of the Texas Rangers.

Acuña's return from injury has been remarkable; through 21 games this season, he boasts a .390 batting average with an astounding 1.179 OPS, highlighting his ability to impact games despite the Braves' inconsistent record. However, he faces stiff competition in the All-Star voting from players like Kyle Tucker of the Chicago Cubs.

Josh Smith of the Texas Rangers has been awarded the AL Player of the Week, despite not leading his team in offensive stats. He had an impressive week with a .423 batting average and an OPS of 1.269, ranking second in the AL. His teammate Evan Carter also had a strong performance, but with fewer plate appearances, he was edged out for the honor. Smith's strong showing was highlighted by two home runs and 30 plate appearances, which tied for the most in the league. This marks Smith's first Player of the Week award and the Rangers' first since May 2024.
