PEORIA, Ariz. -- In some Arizona Fall League seasons, there's a player who has that it factor. Ronald Acuña Jr. Vladimir Guerrero Jr. Kevin McGonigle.
This year, it's Cardinals outfielder Tai Peete. Not only was he the developmental circuit's most electric player, he also was its Offensive Player of the Year. He slashed .351/.441/.662, set an AFL record by tripling in four consecutive games, topped the circuit with 20 steals and ranked in the top five in nine offensive categories. He also finished second in the Home Run Derby on Fall Stars Game weekend.

"Tai does it all," said Peoria Javelinas teammate Ike Irish (Orioles), who hits with Peete during the offseason. "He can steal, he can run, he can throw, he can bang. He's the real deal and he puts the work in. He grinds in the cages. He's perfecting his swing every day. So I'm not really shocked by this."
Peete's virtuoso performance in the Fall League caps an eventful year. A supplemental first-round pick by the Mariners in 2023, he switched organizations this February in a trade for Brendan Donovan. After never having to deal with any sort of serious injury, he sustained a concussion when he was tagged in the head in late May and then came down with an illness that sapped him of 25 pounds, sidelining him for six weeks.
When he returned, Peete -- the Cardinals' No. 17 prospect -- played the best ball of his career. He batted .339/.386/.614 with 10 homers and 11 steals in 39 games between High-A and Double-A, then tore up the Fall League.
Built like a wide receiver at 6-foot-2 and 193 pounds, Peete also features the well above-average speed befitting the position. He has exceptional bat speed, plus raw power and a strong arm that delivered fastballs up to 96 mph when he pitched at Trinity Christian HS in Sharpsburg, Ga. Age is also on his side, as he just turned 21 in August.
There never has been any question about Peete's tools and upside, but there have been some concerns about his bat. He hit .217 last year in High-A and carried a career 31 percent strikeout rate before he was sidelined in the middle of this season.
Peete cut his K rate to 23 percent in the final two months of Minor League play and 18 percent in the AFL. If he can make that kind of contact, he'll be a star.
Peete's swing-and-miss issues stem in large part from an extremely aggressive approach. Interestingly, he has fished for more pitches out of the zone than usual during his hot streak. His chase rate was 35 percent from July through September and 33 percent in Arizona, compared to 28 percent in his first three-plus seasons as a pro.

While Peete has lowered his hands and shortened his left-handed stroke a bit compared to 2025, he says he can't pinpoint any specific alterations that sparked his late surge.
"Maybe just some approach things or maybe small adjustments, but other than that, nothing too much," Peete said. "I don't think anything changed. I just went out there and played and I was grateful to be on the field.
"Maybe it was just dropping my hands a little bit more, maybe smoothing out my movements, less movement for me in the box. It could be I'm getting more comfortable with my swing, getting more comfortable with my stance."
Perhaps the biggest change is that Peete is beginning to understand that he doesn't have to go all out to impact the baseball. Though he made a conscious decision not to swing the bat as hard as he can this season, he slugged a career-best .549, compared to .406 from 2023-25.
"I swing probably about 80 percent all the time," Peete said. "I never usually gear it up to 100. So the balls I'm hitting this year are 80-percent swings. I'd rather put it in contact at this point, so I definitely toned it down."
