The month of October brings baseball fans the excitement of postseason play in the Majors and the dawn of a new Arizona Fall League campaign.

The Surprise Saguaros and Mesa Solar Sox will kick off the 32nd season of AFL competition on Monday at 9:30 p.m. ET, pulling the curtain up on six weeks of prospect-filled action. Right-hander Leandro Lopez (Rangers) will get the start for Surprise against right-hander Jake Walkinshaw (A's) for Mesa.

Players from all 30 organizations will be on hand in the desert, including a number of well-known prospects. Each of the past two seasons have featured 10 of baseball's Top 100 prospects, but that number has risen to 14 for 2024. The league officially released its rosters -- which can be fluid -- on Sept. 25, highlighted by some notable names from each organization.

Of course, the AFL has always boasted its share of upper-echelon talent. Hall of Famers Mike Piazza, Todd Helton and Derek Jeter are just a few of the more than 3,000 Major Leagues who have graced the AFL. Current MLB stars Mike Trout, Bryce Harper and Mookie Betts are among the notable Fall League alumni.

Some of the sport's most talented prospects will be on hand, including Royals 2024 first-rounder Jac Caglianone (No. 17), who made his pro debut for High-A Quad Cities during the summer. Padres teenage sensation Ethan Salas (No. 19), Mariners shortstop Colt Emerson (No. 27) and Giants slugger Bryce Eldridge (No. 35) are among the 14 Top 100 prospects taking part.

Each of the Fall League's six clubs feature talent from five organizations. Those affiliations are:

Glendale Desert Dogs: Cardinals, Dodgers, Phillies, Reds, White Sox
Mesa Solar Sox: Angels, Athletics, Cubs, Rays, Red Sox
Peoria Javelinas: Braves, Brewers, Mariners, Marlins, Padres
Salt River Rafters: Diamondbacks, Nationals, Rockies, Twins, Yankees
Scottsdale Scorpions: Blue Jays, Giants, Mets, Pirates, Tigers
Surprise Saguaros: Astros, Guardians, Orioles, Rangers, Royals

Automated ball-strike (ABS) system

The Fall League has also served as an important circuit for many of Major League Baseball's forward-thinking improvements to the game to get some reps. The automated ball-strike (ABS) system has been in play in the desert since 2022, but was previously just available during games played at Salt River Fields at Talking Stick. This season, that will expand to Camelback Ranch (Glendale), Surprise Stadium and the Peoria Sports Complex (as well as Salt River Fields), meaning that two-thirds of all game action will have the experimental technology available and in use.

Each club will get two challenges -- which can only be initiated by the batter, pitcher or catcher -- but will retain said challenge if successful. (All Triple-A games from June 25 onward this season featured the use of the ABS system, with the revamped two challenges replacing the previous standard of three.)

Oct. 7: Opening Night, 9:30 p.m. ET
