As we approach Week 18 of the MLB season, finding those diamond-in-the-rough players on the waiver wire can be crucial for fantasy baseball success. This week, hitters like Miguel Vargas of the Chicago White Sox stand out for his multi-position eligibility and run-scoring potential. Meanwhile, Mike Tauchman and Nathan Lukes are proving valuable contributors to their teams, with consistent performances in runs scored and batting average. The home run category sees Tyler O'Neill and Giancarlo Stanton as top pickups, both exhibiting power potential following their recent form. In terms of RBIs, Josh Jung has been a revelation since his call-up, while Mickey Moniak's resurgence with the Rockies adds another dimension. For stolen bases, Chandler Simpson and Colton Cowser are rising stars worth adding. Finally, Jordan Beck and Coby Mayo are making headlines for their batting averages, making them worth consideration in deeper leagues.

Jeremy Peña, the standout shortstop for the Houston Astros, is set to kick off a minor-league rehab assignment with Triple-A Sugar Land on Tuesday as he recovers from a fractured rib sustained from a hit-by-pitch on June 27. Manager Joe Espada confirmed Peña has been progressing well, recently taking part in live batting practice. His return is eagerly anticipated, especially given the Astros' struggles during his absence, where they posted an 11-13 record without him.

Peña, a first-time All-Star, was leading the Astros with a 140 OPS-plus and second in Wins Above Replacement amongst MLB position players when he was injured. With a stellar .354 batting average in leadoff spots during the season, his presence is crucial for an injury-depleted Astros lineup that has seen five key players on the injured list, including Yordan Alvarez.

The final weekend before the All-Star break is packed with action, featuring a full slate of 15 MLB games. Start your DFS lineup with pitching recommendations like Joe Ryan from the Minnesota Twins, who boasts a 2.76 ERA despite facing Paul Skenes and the Pittsburgh Pirates, who languish at the bottom in runs scored. Gavin Williams of the Cleveland Guardians is another solid pick against the struggling Chicago White Sox. For a bold choice, consider Chase Burns from the Cincinnati Reds, who has the potential to dominate against a Rockies lineup that has struggled to score runs this season.

Top hitters to consider include Juan Soto, who has shown exceptional form with a recent 1.156 OPS. Despite not being an All-Star, his performance against right-handed pitchers is noteworthy, especially against a floundering Michael Wacha. Also, keep an eye on José Ramírez, who has been central to the Guardians' offense with a .301 average and the potential for big plays, while players like Addison Barger and Willy Adames present great value at lower prices.

Stacking options for the day include the Texas Rangers against Lance McCullers Jr., and the Oakland Athletics facing Max Scherzer, who seems to be past his prime but remains a formidable opponent. With strong options across the board, fantasy players have ample opportunities to craft winning lineups before the break.

The Houston Astros' shortstop Jeremy Peña is sidelined with a left rib fracture, but he remains optimistic about a swift recovery. After being hit by a pitch, Peña was placed on the 10-day injured list retroactive to June 28. Initial X-rays showed no fracture, but further imaging revealed the issue. Peña is currently in recovery, focusing on treatment while traveling with the team and engaging in light exercises.

Despite the injury, Peña expressed confidence in the Astros' depth, noting his teammates' ability to step up during his absence. He currently leads the team in several offensive categories, including OPS and runs scored. As he recuperates, the Astros will likely rely on players like Isaac Paredes and Mauricio Dubón to fill the gaps left by Peña's absence. Peña's expected return is still uncertain, but the team is optimistic he could be ready before the All-Star break.

The Houston Astros are adjusting their lineup following the injury of shortstop Jeremy Peña, who has been placed on the injured list due to a left rib fracture. In response, the team has called up infielder Shay Whitcomb from Triple-A Sugar Land. This marks Whitcomb's third stint with the Astros in recent weeks, although he has struggled at the plate in his previous seven games this season, failing to record a hit in nine at-bats.

Peña's injury, retroactive to June 28, means he could potentially return by July 8. With Peña sidelined, Mauricio Dubón has taken on the shortstop role, having started in the last two games against the Cubs. Dubón's versatility and prior performance could make him a valuable asset in Peña's absence.
