MLB Second-Half Breakout Hitters: Jac Caglianone Is the Buy-Low, Plus the Waiver Bats to Grab Now

The All-Star break is the sharpest manager's favorite buying window. First-half surface stats create panic and hype in equal measure, and the gap between what a hitter has done and what his underlying metrics say he should do is where second-half value lives. Heading into the second half of 2026, the buy-low board is headlined by a young slugger whose batted-ball data is screaming louder than his recent box scores, plus a handful of waiver-wire bats worth adding before the rest of your league catches on.

Jac Caglianone is the marquee buy-low

Jac Caglianone is the name to know. The Royals slugger is hitting in the .270s with an on-base mark around .350 and a slugging percentage near .500, with 14 home runs on the season. His underlying metrics are elite: a strong expected weighted on-base average, a healthy expected batting average, and an expected slugging that all rank in the top tier of the league, with the bulk of his batted-ball indicators sitting in the top 20 percent. The exit velocity is real, the contact quality is real, and the profile is that of a hitter on the verge of stardom.

The opportunity comes from the shape of his season. Much of Caglianone's production has been concentrated in a hot stretch, and a cooler patch can create a buy-low window for managers who trust the process metrics over the recent results. His early-season slump was an extreme example of bad batted-ball luck rather than a skill problem, and the metrics have since caught up to the talent. Managers in a position to buy should target him during any lull, because the underlying data points to a big second half and a hitter whose name recognition is about to climb.

The waiver-wire adds

Beyond Caglianone, several hitters are worth an add or a cheap trade offer. Carson Benge of the Mets has shown a recent surge, stringing together multi-hit games with improved plate discipline, walks, and extra-base pop. His combination of doubles, home runs, and stolen bases gives him a well-rounded fantasy profile, and he can often be acquired at a fair price given that his breakout is still building. In deeper leagues, he is a priority pickup; in shallower ones, he is a name to stash if the playing time holds.

Cam Smith is the classic batting-average-mirage buy. His surface line is dragged down by a low average, but he is on a 20-homer, 20-steal pace with respectable plate-discipline metrics that suggest the average is an aberration rather than the true talent. Managers frustrated by his average may be willing to sell, and the power-speed combination is exactly the kind of profile that can carry a fantasy roster in categories leagues once the batting average normalizes.

The deeper-league targets

For managers in deeper formats, a few additional names are worth monitoring. Samuel Basallo is among the prospect-adjacent bats drawing attention as a second-half target, the kind of high-upside add whose ceiling justifies a bench spot in leagues that reward stashing. Rotating waiver names like Javier Sanoja and Heriberto Hernandez have popped in recent weeks and can provide short-term category help, though their roles and playing time need monitoring before committing significant FAAB.

The unifying theme across these targets is process over results. Each of these hitters has an underlying profile that outpaces his surface line, whether through elite exit velocity, improving discipline, or a power-speed combination masked by a low average. That is exactly the kind of edge that separates managers who make the playoffs from those who chase last week's box scores.

The Verdexed model take

Verdexed's hitter model leans heavily on expected-outcome metrics rather than results, which is why Caglianone grades as one of the strongest buy-low candidates in baseball. His expected stats sit well above his actual production over the full season, and the model projects meaningful positive regression in the second half. The gap between his name value and his true value is the definition of a fantasy edge, and it is at its widest during any cold stretch.

For bettors, the individual-hitter angle shows up in home-run and total-bases props. Caglianone's exit velocity and expected slugging support the over on his power props in favorable matchups, particularly against pitchers who allow hard contact. The broader lesson is to bet the metrics, not the recent line, because the market and the average fantasy manager both overweight the last two weeks.

What to do in your league

Prioritize Caglianone as your top buy-low target. If a leaguemate is frustrated by a cool July, offer a fair but aggressive package, because the profile is that of a future star and the window to acquire him at a discount is narrow. On the waiver wire, Benge and Cam Smith are the highest-priority adds, with the deeper-league names worth a look if you have the roster space.

Above all, trust the underlying data. The second half rewards managers who buy hitters whose expected stats outpace their results, and every name on this list fits that description. The panic sellers and the box-score chasers are your trade partners, and the metrics are your edge.

The FAAB strategy

How much to spend depends on your league's format and your roster construction. In categories leagues, prioritize the power-speed profiles like Cam Smith, because the scarce categories of home runs and stolen bases carry outsized weight in the standings. In points leagues, the on-base and doubles production of a hitter like Carson Benge is more valuable, so weight your bids toward the well-rounded contributors. For the prospect-adjacent names, treat them as speculative stashes rather than must-adds, and only commit meaningful FAAB if a clear path to everyday playing time has opened. The overarching principle is to spend where your roster is weakest and to buy the underlying metrics before the rest of your league reacts to them.

The second half is short, and every add matters more than it does in April. A hitter acquired now on the strength of his expected stats has two-plus months to pay off, and the managers who move early on names like Caglianone and Benge will have them rostered before a hot streak makes them untouchable. Patience with the process metrics and aggression on the waiver wire are not contradictory: the edge comes from trusting the data enough to act before the results confirm it.
