Prepare for an awesome 2023 season

SLO MSBL is preparing for the 2023 adult baseball season and would love for you to join!

The season is scheduled to start on Sunday, April 2. Games are held on Sundays with 10am, 1pm & 4pm start times. With a new team likely joining this season, most Sundays will have games at two different fields. Expect to play 16-20 games during the season.

SLO MSBL has a single 30+ modified age division. Teams are allowed unlimited players over 30 and five under 30. Anyone over 18 years of age is eligible to join the league.

Player fees for the season will be $285. Those fees are payable to the manager of your team who will turn them in to the league. 

Team deposits are due February 15 with the remainder of player fees and initial rosters due March 15. Players can be added after this date until the final roster deadline. But teams must have a minimum number of players on the roster by the initial deadline.

As long as deposits are turned in, the initial league schedule should be available in early March.

The next league meeting is scheduled for Saturday, March 18.

2022 SLO MSBL Champion Angels

Angels win the Championship in 2022

The 2022 season was good for the Angels. Though they had a few close matchups, they escaped the regular season without a loss. Their 14-0-1 record earned them a first round bye in the playoffs.

They defeated the Legends in a sweep in round two to set up a rematch of the 2021 18+ Championship against the Blacksox.

After losing their first game of the season in the first game of the championship series, Pat Haugen pitched a complete game to secure the win in a 2-1 nail biter. He came back out to start game two, but the Blacksox ran out of gas. The Angels cruised to a victory in the deciding game to secure another League Championship

The SLO MSBL is the only amateur adult baseball league serving San Luis Obispo county. It is an affiliated league of the National Men’s Senior Baseball League and is open to all adults 18 years and older.

This is real baseball. The league plays on Sundays in San Luis Obispo, or occasionally in Atascadero, Arroyo Grande or Santa Maria. The games are 9 innings or 2:45 long. The fields are full sized fields with 90 ft base paths, 60’6″ pitching distance and fences ranging from 295′ to 380+.

The season typically runs from early April to early September with playoffs following the regular season. Last year, SLO MSBL had 7 teams with players ranging in age from 18 to 72. Don’t think age will get in the way of your ability to play. The only thing stopping you is…you.

Before each season, the league and managers meet to discuss changes, if needed, for the upcoming season. Divisions and local rules are subject to change before the start of each season to make the league more competitive and fun for players.

Last year, the league ran with a single modified 30+ division. Teams could have unlimited players 30 and over and 5 player under 30. The only restriction for the younger players was that they could only pitch a combined 3 innings per team each game. 

It’s possible, the league may break into two age divisions again. In the recent past, they had an 18+ and 35+ division. The divisional makeup is still to be determined for 2023. Player fees will be determined soon.
