Prepare for an awesome 2023 season

SLO MSBL is excited for the upcoming season. Weather permitting, Opening Day will be Sunday, April 2. There will be 4 games, with 3 taking place at Sinshimer Stadium in SLO and the 4th at Porter Field in AG. 

The first matchup will be a rematch of last year’s championship series as the Angels play host to the Blacksox at 10am Sunday. Also at 10am, in AG, the Hogs and the Legends will face each other to start off their seasons.

At 1pm the middle game will kickoff between the Hops and Eagles. Following that will be the late afternoon game between the Outlaws and the Primos, the new arrival in our league.

It promises to be a great day of baseball. We welcome friends, family and the general public to come out and enjoy a day at the ballpark with us. Admission is free and you are welcome to bring your own refreshments.

See you April 2, 2023!!!

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 Hogs 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. 

2023 will follow the same rules format as last year.

It’s possible, the league may break into two age divisions again at some time in the future. 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.
