This week’s analysis of American League free agents reveals a mix of potential breakout candidates and underwhelming options. Joe Boyle, a promising starting pitcher for the Rays, has showcased elite strikeout potential with a stellar Triple-A ERA and could be a valuable asset if he secures a spot in the rotation. Meanwhile, Joey Cantillo from the Guardians is stepping into a rotation void and could provide quick dividends with favorable matchups. However, veteran Dietrich Enns may be on thin ice following a poor outing, raising concerns about his long-term viability.

Among hitters, Jake Burger is re-establishing himself in the Rangers' lineup, while Brooks Baldwin of the White Sox could gain increased playing time due to injuries. Notable mentions also include rookie prospects like Wyatt Langford, who holds high expectations among fantasy enthusiasts. Bidding strategies reflect these players' potential impacts, with estimated auction values ranging from $1 to $15 across various league formats.

The MLB waiver wire is heating up as several players emerge as valuable fantasy options. Tyler O'Neill of the Baltimore Orioles, with a power upside, has returned from the IL but is currently hitting low numbers. Chandler Simpson of the Tampa Bay Rays has shown impressive speed, making him a solid addition for stolen bases. Evan Carter from the Texas Rangers is back and performing well, while Nolan Schanuel from the Los Angeles Angels is carving a niche for himself with good contact rates and emerging power.

Other noteworthy mentions include Tyler Freeman of the Colorado Rockies, who boasts a high batting average, and Zack Gelof of the Oakland Athletics, who brings power and speed potential. With the season progressing, these players are ones to watch as they could significantly impact fantasy rosters.

This week's Waiver Wire Watch highlights several MLB players who are under 40% rostered in Yahoo! leagues and could significantly boost your fantasy team's performance. Tyler O’Neill of the Baltimore Orioles returns from the IL with promising power potential, while Chandler Simpson of the Tampa Bay Rays showcases elite speed. Evan Carter from the Texas Rangers continues to impress as a post-hype prospect, and Jake Meyers of the Houston Astros is making strides in batting average. Nolan Schanuel is emerging as a solid option at first base for the Angels.

Other noteworthy names include Colt Keith of the Detroit Tigers, who is showing promise as a dual-position player, and Tyler Freeman of the Colorado Rockies, who is becoming a valuable asset with speed. Mauricio Dubon is likely to see increased playing time with Jeremy Peña on the IL. Finally, pitchers like Brandon Woodruff and Shelby Miller could offer significant benefits, with both showing solid performance metrics.

As fantasy managers approach Week 15 of the 2025 MLB season, some players' performances are raising eyebrows and leading to tough decisions. Catcher Austin Wells of the New York Yankees is a candidate for dropping due to his low .215 batting average, hampered by a circulatory issue in his hand. Despite decent counting stats, his poor average makes him a risky hold in shallower leagues. Similarly, Taj Bradley of the Tampa Bay Rays is struggling with a 4.79 ERA and has seen a drop in strikeouts, making him less trustworthy.

Meanwhile, Tommy Edman of the Los Angeles Dodgers is worth holding onto despite an ankle injury, as his underlying stats suggest he could bounce back. Chris Bassitt of the Toronto Blue Jays has been inconsistent but still provides fantasy value due to his durability and strikeout potential. Paul Goldschmidt is on the hot seat, as his recent performance has dipped despite a strong start. Zac Gallen and Tyler Soderstrom also appear on the radar for roster adjustments, with Gallen's delayed potential and Soderstrom's cooling off notable.

In Week 15 of the 2025 MLB season, fantasy baseball enthusiasts have several exciting prospects to consider stashing. Carson Williams, a shortstop for the Tampa Bay Rays, is showing signs of significant improvement, boasting a .326 average with five home runs in his last 12 games. With the Rays in playoff contention and their shortstop situation uncertain, he could make his MLB debut soon if his power surge continues.

Jonathon Long, a versatile first baseman-third baseman for the Chicago Cubs, has also impressed at Triple-A Iowa, posting a .317 average with 13 home runs this season. However, his path to the MLB is complicated by the Cubs' crowded roster, indicating that he may only serve in a reserve role initially. Lastly, Cam Schlittler, a right-handed pitcher for the New York Yankees, has been on a roll with a stellar ERA at Triple-A and is now set to be promoted, making him a valuable addition to fantasy rosters.
