The Tab

One night in August, a Triple-A infielder hit the hardest and longest home run of his season, and almost nobody noticed — because the next night he went 6-for-6 and everybody did. Feverbaseball's engine watched both nights, and the season before them, and it keeps a different set of books. This is what the books say.

By Andy Whetstone · Boston Red Sox

On Friday, August 7, at Polar Park, the Worcester Red Sox are down 2-0 in the second inning when 22-year-old Mikey Romero gets a ball he can do something with and does everything to it. It leaves his bat at 108.3 miles an hour and lands 433 feet away — the hardest and the longest of his home runs this season, his tenth of the year. Later he adds a single at 104.8. Worcester wins 5-4. The recap runs under the headline "WooSox Win on Friday Night at Polar Park."

The next night he goes 6-for-6, and everybody notices that instead.


Saturday, August 8, same park, and Worcester beats Lehigh Valley 19-0. Romero's line: single, home run, single, single, double, single. Six hits in six at-bats. The club announces he's the first player in Worcester Red Sox history to record six hits in a game, and the first Red Sox Triple-A player to do it since Michael Coleman had seven for Pawtucket on June 4, 1999. MLB.com counts him as the fifth minor league player to record six hits in a game this season and just the third to do it in exactly six at-bats. Within a day the line is traveling on its own.

Feverbaseball's engine scored all six balls, in order: 107.6, 100.8, 75.7, 71.8, 90.9, 90.8 miles an hour. The single that opened the night was crushed. The home run left at 100.8 — a fine swing and an ordinary ball that carried. Then a 75.7, a 71.8, and two more at 90-and-change. Six hits, and the engine believed two of them.

Feverbaseball's engine does not think Mikey Romero is a star. It has him hitting the ball 108.2 miles an hour at his best, the 88th percentile of the 416 Triple-A bats it tracks, against a median of 105.1. It also has the typical value of his contact — every ball, speed and angle together — at the 52nd percentile. Dead average. He sits 17th of the 20 names on the site's own Triple-A board. In July he drew one walk in 58 plate appearances. The top of his range is loud. The middle of it is ordinary.


For nearly every ball a Triple-A hitter puts in play, the engine records the speed and the angle, and prices that combination at what the major leagues pay for it — a grid of what a ball hit this hard, this high, is worth, on average, in hits and bases. Add up a season of those prices and you get what his contact was worth. Set that beside what his results paid, and you get a gap.

Romero's gap, month by month this season: −.118 in March, −.083 in April, −.051 in May, +.128 in June, −.103 in July, +.181 in August — that last one on 21 balls in play, a month not half over. Four months underpaid, two months overpaid. The box score has not priced his contact correctly in any month this season, in either direction.

April was his best contact month of the year — his 65 balls in play were worth .400 apiece on the grid — and the league paid him .318 per ball. He hit .241. July was crueler: contact worth .320 per ball across 48 balls in play, paid .218, in the month he walked once.

Across those same 416 Triple-A bats, the median hitter's results outrun his contact by .029 per ball — Triple-A parks and defenses pay better than the major-league grid expects. Romero's season gap, on 267 scored balls, is −.017. That puts him at the 13.5th percentile of the level. About one bat in seven has had results lag contact harder, and against that median the four underpaid months run deeper than they look, the two overpaid ones run shallower.

The league ran a tab on his contact for most of the season. The collection came in five games, August 4 through August 9 — ten hits, two home runs, the 433-footer among them, and a triple at 94.8 — and it came partly in soft coin. Through August 10 his month reads .379/.471/.690 over 34 plate appearances.


Romero first appeared on feverbaseball's Triple-A board in the August 7 edition — published the day before the six-hit game, built on games through August 6. The board did not see him coming. It is a season-long sort by top-end exit velocity, and his season figure barely moved that week; he entered because names above him graduated to the majors or were found by the consensus the board exists to beat. His rolling top-end contact was at its season low entering August — 108.2 over his trailing 75 balls as of June 22, down to 103.7 by August 3 — and his rolling average exit velocity fell with it, 90.7 to 88.0. The site's own caption explains that the rolling line can fall in the same weeks a hitter's typical contact rises. Here even the middle fell. The best week of his season was not driven by a surge in how hard he hit the ball. It was the tab coming due, plus some soft hits falling.

The row sat on top of a season-long record: 88th-percentile top-end contact from a hitter carrying an OPS under .700. While the results said what they said, the instrument kept saying the contact was worth more.

EV95 measures how hard he hits it at his best, not how often. Romero puts 42.2 percent of his batted balls in play at 95 miles an hour or better, against a league median of 36.8 — good, not rare. And the top was there before the week and before the season: in 2025, on 121 tracked balls at this same level, on this same instrument, his EV95 was 107.7; this season it's 108.2. "I don't want to be cocky but 109 [mph], I feel like I've done it before," he told Talk Sox in April. Whatever August was, it wasn't a new ceiling.

MLB Pipeline has him ninth in Boston's system and the fifth-best third-base prospect in the game; Baseball America and Prospects Live both have him 18th; SoxProspects had him 22nd in January. Baseball America grades him a 45 on the 20-to-80 scouting scale, where 50 is an everyday major leaguer. FanGraphs' player page carries no grade at all as of August 13. Nobody's list says star. The card market has gone further and said nothing: the PSA 10 of his flagship autograph moved a tenth of a percent over the seven nights through August 11, by SportsCardsPro's market read — flat through the six-hit game. The collector market, whatever else it prices, hasn't noticed him. And the board row is the only notice the site itself has ever taken of him.


The rarest number on his page is games played.

Boston drafted Romero 24th overall in 2022, out of Orange Lutheran High School in Southern California, and paid him $2.3 million to skip LSU. He was hurt before he ever reached his first spring training — back stiffness that became a stress fracture, Talk Sox reported — and played 34 games in all of 2023. He didn't debut in 2024 until May. "I came back in the first week of May and was on a program where I was building back up in games," he told SoxProspects in January. Then 2025 finally let him play: a career-high 111 games and 54 extra-base hits — the most of any Red Sox minor leaguer, by MLB Pipeline's count — the last 45 of those games at Worcester. Across 2024 and 2025 he hit 98 extra-base hits in 189 games. "I felt strong all year. I hit PRs in 90th percentile exit velo," he said in the same interview.

This season is his second straight healthy one, all of it in Worcester: 89 games through August 12 — 43 at third base, 32 at second, 14 as the designated hitter, and not an inning at shortstop, which he played as recently as last season in Portland. "Honestly, I think third and second [base] are easier," he told Talk Sox. "Third base is such a reactionary position that if the balls hit to you, you're using one hand for the majority of the time." Alex Cora took a long look at him at second base in spring training, the Boston Globe reported in February, and he played second the night of the six hits. "Whatever the team needs me to do," he said in that same Talk Sox conversation.

Hitting is the family business, and he's not even its most decorated branch. His sisters Sierra and Sydney played college softball at Michigan and Oklahoma, and both played in the Athletes Unlimited Softball League's inaugural 2025 season; a third sister, Sophia, plays in college now. Their father coached them all.

And the friend a year ahead of him is gone. "I FaceTimed Marcelo, and we're just going crazy," Romero said in the Boston Globe's coverage of draft night 2022. Marcelo Mayer — the best friend from SoCal travel ball, Boston's fourth overall pick in 2021 — was Boston's second baseman until June, when a stress reaction in his left ulna put him on the injured list. On August 3, still on the injured list, he was traded to San Francisco for reliever Erik Miller. Five days before the six-hit game, the man whose road Romero had been following was traded off it. Trevor Story has been out since hernia surgery in May. Kristian Campbell, who signed an eight-year, $60 million extension in the spring of 2025, has spent all of 2026 in the same Worcester infield as Romero.


Romero isn't on the 40-man roster, and this December, for the first time, Boston has to decide: protect him or expose him to the Rule 5 draft, where any team could take him. Through August 12 the season line is .237/.301/.386 with eleven home runs. The record underneath it says the contact was worth more than the league paid in four months out of six; that about one Triple-A bat in seven got shorted harder; that the top of his range is 88th percentile, was there last year too, and put a ball 433 feet from home plate the night before the famous one; that the middle is 52nd; that this is the second straight season his back has let him play; and that in July he walked once. None of it is a forecast — 21 August balls in play are 21 August balls in play.

Somebody in that room in December will make the case for him. Written down, the case is not that a star arrived in August. It's that a healthy, ordinary-to-good hitter with a loud top end spent a season being paid less than his contact earned, and for five games in August the league paid him back. Not all of it — on the season, his results still trail his contact, at a level where the typical bat's results run ahead of its contact. The decision belongs to the room. The tab is still open.
