San Francisco Giants slugger Bryce Eldridge has emerged as one of the league's most intriguing young power hitters during his second major league season. After appearing in just 10 games in 2025, the 21-year-old has launched seven home runs while slashing .274/.365/.476 with an .841 OPS across 47 games. The former first-round pick possesses elite underlying metrics that support his breakout. His 54.6 Hard-Hit% ranks in the 98th percentile, while his .374 xwOBA sits well above league average. Eldridge has also paired his power with a strong 12.4 BB%, showing a polished offensive approach. Fantasy managers searching for home run upside should target Eldridge as a high-impact waiver wire addition before his roster percentage climbs.

Milwaukee Brewers right-hander Brandon Sproat has endured an inconsistent first full major league season after making four appearances with the Mets during his 2025 rookie campaign. The 25-year-old owns a 5.13 ERA, 1.37 WHIP, and .244 opponents' batting average across 17 appearances, including 15 starts. Sproat showed encouraging progress in June, however, posting a 3.46 ERA during the month. His 25.3 K% remains comfortably above league average and highlights the swing-and-miss ability that holds his ceiling high. Limiting hard contact remains the biggest hurdle, but his recent performances point toward continued improvement. Fantasy managers searching for pitching upside should consider Sproat a worthwhile buy-low waiver wire target before his value climbs.

Rockies outfielder Cole Carigg continues to emerge as one of the top waiver wire targets after an outstanding start to his rookie season. The 24-year-old has already launched four home runs while posting a .940 OPS through his first 24 major league games. Carigg has been even better recently, hitting .349 with a .581 slugging percentage over his last 15 contests. The No. 6 prospect in the Rockies organization has also made an impact beyond the batter's box. His 99th percentile arm strength and 92nd percentile sprint speed highlight his all-around skill set. With his confidence growing and production remaining steady, Carigg profiles as a high-upside fantasy addition in all league formats.

Guardians left-hander Joey Cantillo has put together a strong 2026 campaign, posting a 3.86 ERA, 1.36 WHIP, and 89 strikeouts across 91 innings in 18 starts. The 26-year-old looked like one of the American League's biggest breakout pitchers early in the season before encountering some turbulence in June. Cantillo recorded a 4.50 ERA during the month, with his 11.5 BB% contributing to the inconsistency. Even so, he has consistently shown the ability to make adjustments and rebound from difficult stretches. His strikeout upside and overall body of work continue to support his fantasy value. Managers searching for rotation help should view Cantillo as a high-upside waiver wire addition in all league formats.
