Mack has gone yard four times in 14 games since the All-Star break, and through his first 215 big-league plate appearances he's produced a .245/.299/.449 slash line with 11 homers and 33 RBI.

Rotowire
Mack went 1-for-4 with a two-run home run in Tuesday's loss to the Astros.
The rookie catcher made things interesting by taking AJ Blubaugh deep in the seventh inning with the Marlins down 5-1, but they couldn't creep any closer.

Marlins' Joe Mack: Scores three times in four-hit game
Rotowire
Mack went 4-for-4 with three runs Tuesday in the Marlins' 10-6 win over the Diamondbacks.
With a .203 batting average, the rookie catcher was barely sitting above the Mendoza Line for the season at the end of May, but his bat has begun to heat up in June. Through seven games on the month, Mack has gone 9-for-23 with a home run and a double, lifting his season average up by 50 points in the process. Mack is still expected to provide most of his value to the Marlins through his defense behind the plate, but he offers a bit of pop and should play frequently enough to make for a viable lineup option in fantasy leagues that start two catchers.

Rotowire
Mack went 1-for-3 with a two-run home run and an additional RBI during the Marlins' 7-3 win over the Nationals on Tuesday.

Rotowire
Mack went 2-for-4 with an RBI in Tuesday's loss to the Orioles.
A third-inning single by the rookie catcher brought home Kyle Stowers, giving Mack his first hit and RBI in MLB, and he added another knock in the eighth. The 23-year-old top prospect will get a long look in the starting role from the Marlins, with Liam Hicks -- who got the start at first base Tuesday before taking over behind the plate for the top of the ninth after Mack was lifted for a pinch runner -- seeing more of his playing time at 1B and DH as a result.

Marlins' Joe Mack: Day-to-day with stiff neck
Rotowire
Marlins manager Clayton McCullough said Monday that Mack is dealing with a stiff neck but should return to the Grapefruit League lineup in a couple days, Christina De Nicola of MLB.com reports.
McCullough noted that if it were the regular season, Mack would most likely play through the injury. Mack has appeared in seven games this spring for Miami, going 3-for-18 with one home run at the dish. He's third on the Marlins' catching depth chart and will begin the season at Triple-A Jacksonville, barring an injury to Agustin Ramirez or Liam Hicks.

Marlins' Joe Mack: Having huge finish to year
Rotowire
Mack went 1-for-4 with a walk, a two-run home run and a second run scored for Triple-A Jacksonville on Wednesday.
The 22-year-old backstop walked it off for the Jumbo Shrimp in the bottom of the 10th inning, giving Mack his 20th homer of the year between Double-A and Triple-A. He's gone yard in four straight games, and over his last 12 contests for Jacksonville he's slashing .325/.383/.950 with 10 of his 13 hits (two doubles, a triple and seven homers) going for extra bases. The presence of Agustin Ramirez ahead of him on the organizational depth chart complicates his timeline, but Mack appears ready to make his big-league debut in 2026, and he could be competing for a 26-man roster spot in spring training.
