Joe Mack Fantasy Stats

Miami Marlins catcher Joe Mack has been called up from Triple-A Jacksonville on Sunday. In a somewhat shocking decision, Agustin Ramirez has been demoted, while Mack receives the call to The Show. Mack is regarded as one of the team's top prospects and should get a legit shot to show off his skills. Mack hit .244 with three home runs, nine RBI, and one stolen base across 24 games in Triple-A this season. Liam Hicks has been swinging the bat well in Miami, but Mack should eat away at his playing time. The Marlins aren't going to call up Mack to have him ride the bench. Mack is viewed as a highly-regarded catching prospect and could have elite value at the position. Any fantasy managers in need of help at the catching position should consider adding him.

Miami Marlins catching prospect Joe Mack was sent to Triple-A Jacksonville on Sunday afternoon. The young catcher was unlikely to break camp with the MLB roster and will now officially begin his 2026 season at the top level of the minor leagues. The 23-year-old spent most of spring training as the No. 3 catcher on the depth chart behind breakout Agustin Ramirez and Liam Hicks. In 2025, Mack spent most of his season with Triple-A and posted a solid .250/.302/.459 slash line with 18 doubles, 18 home runs, and a 115:35 K:BB. He also swiped eight bags. Earlier in the season, he posted an elite .318/.464/.614 line over a brief taste of Double-A action. Even though Mack was unable to crack the Opening Day roster, he remains on track for a first-half promotion and is worth monitoring in deeper two-catcher leagues.

Miami Marlins catching prospect Joe Mack (neck) returned to the starting lineup during Tuesday's spring training contest against the Washington Nationals. The young back was sidelined for a few days due to neck stiffness, but quickly returned to action. In his return, Mack struggled at the plate, going 0-for-3 with a strikeout. The former 31st overall selection is in serious consideration to break camp with the MLB roster. Last summer, Mack spent the majority of his campaign at Triple-A (99 games), where he hit .250/.320/.459 line with a .779 OPS. During this stint, Mack hit 18 home runs and carried a modest 115:35 K:BB. If Mack can enjoy a strong conclusion to camp, he could contend for a depth role on the MLB roster. If he were to fall short, he would be in contention for an early promotion.

Miami Marlins catching prospect Joe Mack is a name to keep a close eye on during spring training. Mack is currently considered the No. 4-ranked prospect in the Miami system and No. 70 overall on MLB.com. The 23-year-old began the 2025 campaign with Double-A but needed only another 13 games there to prove he was ready to join Triple-A Jacksonville. During his first taste of action with the top club in the minor leagues, Mack held a .250/.320/.459 line with 18 doubles and 18 home runs. Through 99 games, Mack swiped eight bags but carried a 115:35 K:BB. He was used primarily behind the dish, as he logged 83 of his 112 total games behind the plate. Given that Agustin Ramirez struggled as a catcher during his first stint in the major leagues and was nearly deployed just as often as a DH, Mack could be a strong candidate to be the team's primary catcher early in 2026.

Miami Marlins catching prospect Joe Mack went just 1-for-4 on Tuesday for Triple-A Jacksonville, but his lone hit was a big one, a two-run walk-off home run in the bottom of the 10th inning. The Marlins' third-ranked prospect has now homered in four straight games and five of his last seven, bringing his season total to 20. The 22-year-old now owns a .256/.336/.474 slash line with a .360 wOBA and 119 wRC+ in 106 games this year (93 at Triple-A, 13 at Double-A). The 22-year-old is trending toward a major league debut next year, and with some good power, he could be intriguing for fantasy, however, the Marlins also have plenty of young depth right now at the position, with both Agustin Ramirez and Liam Hicks handling duties behind the plate. So, Mack would have to somehow find regular at-bats when he gets there to make himself fantasy relevant.

Miami Marlins catcher prospect Joe Mack went 2-for-3 with a home run and two RBI against Triple-A Rochester on Tuesday. Mack connected for his 15th homer of the season, marking his second straight game with a long ball. The lefty hitter has been surging in the second half, owning an .884 OPS with 10 homers compared to a .693 OPS with five homers in the first half. He has a typical catching profile with plenty of power and patience at the plate, with some swing and miss concerns. The 22-year-old is hitting .243/.312/.411 in 309 plate appearances at Triple-A this season. There's a chance we see him in the majors before the end of the year, and he would likely only be worth considering in NL-only leagues.

Miami Marlins catching prospect Joe Mack continued to swing a hot bat during their contest against Triple-A Charlotte on Tuesday evening. In this contest, Mack went 4-for-4 at the dish with two long balls, three runs, and four RBI. This impressive performance also extended his current hitting streak to seven games. During this surge at the plate, the backstop has hit five home runs. However, before this impressive streak, Mack posted a modest .125/.196/.125 line through his previous 13 games at Triple-Jacksonville. Overall, throughout his first 51 games at the top level of the minor leagues, the No. 8-ranked prospect in the system has posted a .262/.324/.419 slash line with seven home runs. If Mack can continue this impressive power surge, he could reach the majors in the second half.

Miami Marlins catching prospect Joe Mack homered on Sunday in a 2-for-4 day at the plate for Triple-A Jacksonville. It was the third home run in his last four games, and the hits extended his current hit streak to six games, during which time he's gone 12-for-25 (.480) with a pair of doubles, three home runs, five RBI, six runs scored, and a stolen base. The 22-year-old also struck out six times compared to just one walk over that span. The left-hand hitting backstop slashed .318/.464/.614 in 13 games at Double-A this season before getting promoted to Triple-A, where he's tallied a .246/.311/.374 slash line over 50 games. The Marlins are deep at the position, with catchers Agustin Ramirez and Liam Hicks already promoted to the majors this year, but if Mack can continue to hit, he could be the next to be called upon if one of them or Nick Fortes were to hit the injured list.

Miami Marlins catching prospect Joe Mack went 2-for-4 with a home run during their contest against Triple-A Nashville on Thursday evening. Over his last three games with Triple-A Jacksonville, Mack has tallied at least one hit in each game and gone 5-for-13 with two extra-base hits. Before this surge at the plate, Mack went 6-for-44 during his first 12 games of the month at Triple-A. Mack opened the campaign with Double-A but was eventually promoted to Triple-A. Through his first 47 games at the top level of the minor leagues, Mack has struggled at times, holding a .223/.291/.320 slash line with a 51:5 K:BB. However, it appears the 22-year-old is starting to find his footing. If the No. 8-ranked prospect in the system can continue to find his swing, he could earn a call to Miami in the second half of the season.

Miami Marlins catching prospect Joe Mack has held his own during his first look at the Triple-A level. Mack was promoted to Triple-A Jacksonville earlier in April. Through his first 10 games at the top level of the minor leagues, Mack has posted a .270/.372/.486 slash line with two doubles and two home runs. He has held an 11:5 K:BB, tallied three RBI, and scored five runs. Earlier in the campaign, Mack held a .318/.464/.614 slash line at Double-A. Last season, the No. 9-ranked prospect in the Miami system posted a .241/.322/.456 line across 112 games at Double-A. Fantasy managers should continue to monitor his progression as he could eventually earn a promotion to the majors later in the season. However, with Agustin Ramirez now in Miami, Mack will likely only see a part-time role when he earns the call.
