MLB top signings and trades through mid-April: early winners and surprises

Baseball’s early weeks rarely tell the full story, but they do create plenty of headlines. Fans and pundits are already parsing every at-bat and inning for clues about how high-profile offseason moves are shaping the season — and whether those investments look smart after just a few weeks.

Below is a fresh, team-focused look at how several big free-agent signings and trades have fared in the first slice of the schedule. Think of it as a snapshot: small sample sizes, meaningful signals, and a few oddities worth watching as the season unfolds.

Big-ticket free agents: who’s heating up and who’s cooling off in April

Kyle Tucker — Dodgers’ $240 million signing showing early rust

Kyle Tucker arrived in Los Angeles with sky-high expectations after a major free-agent deal, but his first month at Dodger Stadium has been underwhelming at the plate. Across his opening plate appearances he’s produced limited power and a high strikeout rate, translating into an OPS that’s well below what fans hoped for. While the team’s overall record hasn’t flagged — the Dodgers are still winning — Tucker’s swing timing and run production haven’t matched the contract’s premium billing.

• Early statline: modest batting line and just one home run in his initial duty.
• What to watch: plate discipline adjustments and whether the power returns once his timing syncs with new surroundings.

Edwin Díaz — Dodgers’ closer with a small-but-notable velocity dip

Edwin Díaz’s late-inning work has raised eyebrows, largely because his heater has ticked down slightly from prior seasons. The decline is measured in tenths of a mile per hour — enough for analysts and coaches to notice — and came into focus after a blown save during a recent outing. Díaz has acknowledged past patterns of needing time to ramp back after knee surgery, and the manager described the club’s feelings about the situation as a contained, ongoing worry. Given the Dodgers’ recent history with pitcher injuries, caution is understandable.

• Key detail: half-mile-per-hour drop in average four-seam velocity compared to recent baselines.
• Implication: monitor spin rates and late-season velocity trends before drawing firm conclusions.

Power-profile hitters: mixed results and promising underlying metrics

Pete Alonso — Baltimore’s big signing with encouraging Statcast signs

Pete Alonso’s raw numbers through his first stretch of games looked quiet, but deeper metrics tell a more optimistic story. His surface batting average and slugging were down, yet Statcast measures — exit velocity, hard-hit percentage and quality of contact — have shown a lot of positive red flags, suggesting better outcomes could be coming. Alonso’s clubhouse energy and the oddball moment with a fan wearing a polar bear head during a home run have only added to the narrative: the results may lag the process, but the process looks healthy.

Starting pitchers who have delivered early

Dylan Cease — Blue Jays’ rotation piece already making an impact

Dylan Cease has been one of the few bright spots in Toronto’s uneven start. Through his first few turns he posted a low ERA, high strikeout totals and an above-average ability to induce weak contact, even if command has shown volatility at times. Walks remain a part of his profile — an imperfect piece of the puzzle — but Cease’s ability to miss barrels has kept him effective despite the club’s broader struggles.

Framber Valdez — Tigers’ two-seamer needs work, changeup is elite

Valdez has alternated between dominant outings and a rough start, a pattern that makes him hard to peg early on. His changeup has been a weapon, producing swing-and-miss and weak contact alike. The two-seam fastball, however, has generated fewer positive outcomes, leaving room for improvement. The early chemistry with his catcher has been notable, and the club will hope that steady pairing helps Valdez settle into a more consistent rhythm.

Trades and new rotations: early winners and questions

Edward Cabrera — Cubs’ trade pickup gives rotation depth but still walks a tightrope

After the trade from Miami, Edward Cabrera has posted strikingly low earned-run numbers and solid strikeout totals over his first extended look in a new uniform. That said, the walk rate remains an issue he’s battled before; the early success is encouraging but must be balanced against control concerns. Meanwhile, the Marlins appear to have a bright rookie in Owen Caissie, whose combination of power and promising Statcast indicators has given Miami fans reason to smile.

Freddy Peralta — Mets’ rotation addition working toward top form

Freddy Peralta’s initial outings with his new club have been serviceable but not yet All-Star level. He’s posted a mid-3 ERA across his first few starts and shown flashes of swing-and-miss stuff, yet consistency is the missing piece. The prospects sent in the deal have been off to slower starts in the minors, a reminder that trades can take time to fully evaluate.

Middle-market signings and local reactions

Alex Bregman — Cubs’ high-price free agent not yet elevating the lineup

Alex Bregman’s early slash line has been pedestrian and the team sits just under .500 amid a rash of pitching injuries. Bregman’s bat should stabilize the offense over time, but the rotation’s health will ultimately determine how much impact he can have on the win column.

Bo Bichette — Mets’ new infielder facing early boos amid slow start

Bo Bichette’s first weeks in New York produced a disappointing slash line, and the reactions from Citi Field have been immediate and vocal. Fans are impatient, and a continued slump could amplify the pressure, even though analysts caution that 70–80 plate appearances is a tiny sample for determining long-term value.

Munetaka Murakami — White Sox slugger flashes power but needs steadier outcomes

Murakami arrived with a boom, slugging three homers in his first three games, but overall results have been uneven. The encouraging parts: he’s not chasing bad pitches and is frequently making hard contact. Statcast suggests he’s getting unlucky on some high-velocity fastballs — his expected numbers on those pitches are better than what the scoreboard shows — and his personality has energized the clubhouse.

Young contributors and early surprises

• Owen Caissie (Marlins): a promising rookie line with power indicators and solid early Statcast readings.
• Prospect notes: the players exchanged in several trades have mixed starts in the minors, underscoring how early scouting grades can take time to manifest.
