​Players rise and fall in fantasy baseball with equal ferocity. That’s the nature of the game: it’s volatile, dynamic, and demands constant attention from managers who must stay sharp around the clock. As we stretch into the two-thirds mark of the regular season, it’s the moment to rev up that diesel and fuel a playoff push. If you’re scouting for sleeper adds who can help you clinch a spot, the waiver wire is littered with intriguing prospects ready to contribute now.
The Mets have a rookie outfielder who has been quietly producing solid numbers. He’s carrying a .278 batting average and an .808 OPS to complement 7 home runs in 180 at-bats and 9 stolen bases. His RBI total sits at 24, and over a short career so far, he’s shown steady improvement. A look at his recent trends reveals a May .238 mark, followed by a hotter .300 in June and a .308 clip so far in July, signaling a player who may be entering a sustained hot streak.
Strike while the iron is hot, as they say. Pallante has shown flashes of potential, with a 3.16 ERA across 31.1 innings in June and a flawless 0 earned runs over 5.2 innings in his lone July start. Had May not been rough, his ERA would likely be comfortably under 3.50. He is a ground-ball pitcher who may not rack up strikeouts, but his efficiency helps keep runs off the board and his win potential remains solid, sitting at 10-5 for the season.
Tolbert’s career is in its early stages, yet the early returns are impressive. In 2025 with the Royals, he hit .280 in 50 at-bats and swiped 21 bases. In 2026, he’s remained hot, batting .365 with a .904 OPS across 52 at-bats and stealing 10 bases. The dual threat of a second baseman and outfielder gives him versatility, and his ongoing role looks secure for the foreseeable future.
The Twins’ first baseman is enjoying a strong stretch in July, batting .400 for the month and lifting his season average to .255. He’s showcasing power as well, with a .823 OPS anchored by 16 homers. This hitter features notable power and speed metrics, including a high Batting Run Value and elite Bat Speed, making him a compelling add for teams looking to bolster production across the board.
In the Rockies organization, the No. 6 prospect is making his major league impact. Carrigg is batting .307 through 88 at-bats with 4 home runs and a .923 OPS. The switch-hitter, at 24 years old, has moved into the 5th spot in the Rockies’ batting order and carries ample upside. Rookies with this kind of upside are a low-cost lottery ticket worth considering, as early returns can translate into meaningful returns for fantasy managers who pounce at the right time.
As you weigh these options, remember that waivers are a pipeline for upside. The volatility of rookies and breakout candidates means there’s inherent risk, but the potential payoff is substantial for those who identify the right players at the right moment. It’s a game of timing, leverage, and informed optimism, and these waiver-wire targets present a meaningful opportunity to energize a playoff push.
This recap highlights players who have shown recent momentum and have a reasonable path to continued opportunities. If you’re looking to maximize your late-season upside, these names are worth monitoring closely as game plans shift and rosters adjust for the stretch run.
