One AL Playoff Player From Each Team to Watch on the Hobby Market

October can change a player’s card market fast

Major League Baseball’s postseason has a long history of turning strong players into hobby names. A big October can create lasting card demand, especially when a player already has a recognizable rookie card, a memorable playoff moment, or a recent surge that collectors can connect to a deeper run.

For American League playoff teams, that means there are several players whose markets could move quickly if they deliver when the games matter most. Some already have postseason résumés. Others are still building theirs. All of them have a path to a stronger card market if the spotlight finds them again.

Houston Astros: Jeremy Pena

Jeremy Pena is one of the clearest examples of a player whose hobby profile was shaped by October. He broke out as a rookie in 2022 with a huge postseason run, batting .345 with four home runs and eight RBI in the playoffs. That performance helped him earn both American League Championship Series MVP and World Series MVP honors after the Astros beat the Phillies to win the title.

Pena has remained a useful major leaguer since then, and he turned in a solid 2026 season despite playing a career-low 112 games. He matched his career high with 22 home runs, hit .277, and drove in 56 runs. Even so, his card market still appears to have room to move if another playoff run brings back memories of his championship stretch.

What makes Pena especially interesting to collectors is that some of his rookie cards remain relatively affordable. He was a rookie in 2022 products, and the source notes that a PSA 10 of his 2022 Topps Chrome Sapphire rookie sold for just $19 on auction according to eBay sold listings. That kind of entry point leaves plenty of room for a postseason bump if he produces again in October.

Chicago White Sox: Munetaka Murakami

Munetaka Murakami enters the postseason conversation as a power bat with a chance to make a quick impression. His rookie season was uneven in terms of batting average, but the power was real. In 127 games, he hit 35 home runs and drove in 77 runs.

Murakami’s hobby appeal comes from the possibility that a few big swings can change the narrative. The source points to a brief stretch this summer before his injury when he was one of the hottest players on the market. If he gets rolling in the postseason and starts driving the ball out of the park, that kind of production can matter quickly for collectors.

His base rookie refractor remains inexpensive by comparison to many other young power hitters. According to Card Ladder, his latest sale of a rookie Topps Chrome refractor went for just under $10. That low price makes him a player whose market could respond sharply if the home runs arrive at the right time.

Cleveland Guardians: Travis Bazzana

Travis Bazzana is another player whose market could benefit from a strong October because of the story attached to him. The former No. 1 overall pick is heading into his first postseason after his first major league season, and that alone gives him a built-in collector storyline.

The Australian native hit .245 with 15 home runs and 57 RBI during the year, but his most recent stretch has been more encouraging. According to MLB.com, his previous 30-day stat line showed a .288 average with six home runs and 21 RBI. That kind of late-season production can help a rookie’s market, especially when the postseason adds a new stage.

Bazzana’s cards are still relatively accessible compared with some other top rookies. Card Ladder shows that the latest sale of his PSA 10 2024 Bowman Draft Chrome 1st was $140. For collectors looking at a player with both draft pedigree and a chance to build an October moment, that price point keeps him on the radar.

Boston Red Sox: Roman Anthony

Roman Anthony has already been a favorite among collectors since he was drafted in 2022. His hobby profile grew further when he hit .292 with eight home runs and 32 RBI in just 71 games during his rookie year in 2025. But his market took a noticeable hit in 2026 after a rough start to the season.

Anthony’s recent return to form is part of what makes him interesting now. After an extended injury absence from May 7 to August 30, he has shown signs of a rebound. Over his last 30 games, he has hit .273 with four home runs and 10 RBI. If that trend continues into his first postseason, collectors may start looking back at the reasons he drew so much attention in the first place.

Not all of Anthony’s cards are cheap, especially some Bowman Chrome 1st parallels and rookie cards, but there is still a lower-cost way into the market. The source notes that his base Topps Chrome rookie refractor can be found for around $10. That makes him a player whose October performance could matter quickly for both current holders and new buyers.

New York Yankees: Cam Schlittler

Cam Schlittler is not on this list because he is inexpensive. He is here because he has already shown he can create a market spike with big-game performance, and another strong postseason could push him higher again.

As a rookie, Schlittler posted a 1.26 ERA and delivered a 12-strikeout game against the Red Sox in the American League Wild Card Series. That kind of performance is exactly the sort of moment that can shape a young pitcher’s card market. He then backed it up with a strong 2026 regular season, which only adds to the appeal.

His market is already active. According to Card Ladder, his Topps Chrome rookie aqua refractor numbered to 199 last sold for more than $500. At the same time, his base refractor remains much more affordable, with the last sale listed at $6.75. If he adds another standout October outing, the gap between those cards could become even more relevant to collectors watching his market.

Tampa Bay Rays: Junior Caminero

Junior Caminero had a true breakout season and enters the postseason with one of the strongest stat lines of any player on this list. He hit .276 with 42 home runs and 101 RBI, a line that could put him in the mix for first-place MVP votes.

Because his market is already hot, the timing matters. In a normal setting, collectors might wait for prices to settle before buying in. But the postseason has a way of changing that calculation, especially for players who can add to an already impressive year with a memorable October run.

This will technically be Caminero’s second postseason, though he appeared in only two games as a rookie in 2023. Now he is back in the playoffs for the first time in three years, and that gives him a chance to add a new chapter to his hobby profile. If he starts hitting home runs in meaningful games, the attention could follow quickly.

For a lower-cost entry point, the source points to his Bowman's Best rookie refractor. Card Ladder shows that his base refractor from that product last sold for under $7. Bowman's Best is not considered a high-end product, but it can still offer a strong-looking card with room for a player’s market to grow if his postseason production keeps building.

Why playoff production matters so much for collectors

October is different from the regular season because every big hit, strikeout, or clutch defensive play gets amplified. A player with a strong postseason can create a fresh wave of interest even if his cards have already cooled during the summer. That is especially true for young players, rookies, and stars whose best hobby moments are tied to a memorable run.

That dynamic is what makes players like Pena, Bazzana, Anthony, Schlittler, Caminero, and Murakami worth watching. Some already have established markets. Others are still relatively affordable. In either case, a deep playoff run can quickly change how collectors view a card, particularly when the player has a defining moment that people remember long after the final out.

For collectors tracking the American League postseason, the key question is not just who wins, but who becomes the face of the run. In hobby terms, that answer can show up in sold listings, refractor prices, and renewed interest in rookie cards almost immediately.
