2020-2021 Season

COVID-19 Information


With the most recent order from the governor allowing youth and adult sports to resume practice starting on January 4th, and games to begin no sooner than January 14th, the dome committee has been working hard with RCTC to get our RMSS Senior Dome Softball COVID-19 Related Game Rules & Procedures Plan approved, and we received that approval on January 7th. The RMSS Dome Softball season is now officially set to begin with the first practice to be held on Monday, January 11th, at 8 AM. The player draft for Wednesday games will then be conducted on Wednesday, January 13th, at 11 AM, and the first competitive game will be on Wednesday, January 20th. Please read the full Game Rules & Procedures text below.

The dome committee will remain abreast of the most current governor orders and guidelines and will provide any updates or changes to our COVID-19 protocol throughout the season. Any changes/updates will be posted on the senior dome softball website, sent out in an RMSS email and communicated at the start of each day's practice or game.

RMSS Senior Dome Softball 

Covid-19 Related Game Rules & Procedures 

Adopted by Senior Dome Softball Committee on January 6, 2021 

IMPORTANT: RMSS Senior Dome Softball’s primary concern in dealing with the COVID-19 pandemic is the health and  welfare of players and their families. We will implement these safety measures so that we can get back on the field as soon  as possible. Players who choose not to follow the safety rules will be counseled one time and then asked to leave the  session. We appreciate your cooperation in following these new procedures. 

All players will be required to complete and present proof of completion of the MN State COVID-19 Self-Assessment. This  must be done each day before coming to the dome. The Self-Assessment can be found online at Upon completion of the assessment, player will see a  green approval screen with current date that must be presented at the entrance desk of the RCTC Sports Center, East  entrance (the building directly South of the dome), as documented proof for the required daily Self-Assessment. Green  approval screen may be screenshot, displayed in an email, or printed on a sheet of paper. This online Self-Assessment  process is a statewide Minnstate College and University requirement for any person coming on campus. There is a tablet  available at the Sports Center desk for those that have forgotten to complete the assessment or for those that don’t have  access to complete the assessment at home. 

Spectators are not allowed in the Dome under the current Governor’s order. 

Social Contact before, during and after the game: 

  • Do not come to play if running a fever and/or feeling sick. 
  • All Dome players will be required to wear masks from the time they enter the dome until the time they exit the dome. 
  • Players will be expected to maintain social distancing (6 feet of distance) before and after the game, as well as during the  game as much as possible. 
  • There will be a “no-contact, no-handshake policy” to be observed at every level of the organization until further notice.  This includes all physical contact. We will be verbally communicating “good game”, without shaking hands, high-fiving or  fist-bumping. 
  • Pregame batting practice will be left to player discretion. However, for those choosing to participate, social distancing  must be maintained at all times. 
  • Any gatherings after the game, players should continue to maintain social distancing requirement.
  • Each player should bring their own personal sanitizer with them and sanitize their hands and bat before participation. 


  • Maintain social distancing in and out of the dugout. Players from the team at bat will be required to stay separated, with  only those players who are next in line to bat in the dugout. No more than 3 players should be in the dugout at any time.  Other players remain along the outer walls and maintain social distancing. 
  • Managers, or players they designate, will use a disinfectant in the dugout area (bench, bat racks, etc.) prior to each game.
  • When leaving the dugout at the end of the game, each team will need to clean up the dugout and get rid of trash, etc.
  • The league will not furnish water for players. Each player is responsible for their own water container (with players name  on it). Keep close or in players bag to maintain cleanliness. 
  • As per dome rules, no sunflower seeds, chewing or spitting allowed in the dome.

The Game: 

  • It will be mandatory for catchers, umpires and sub-runners to maintain social distancing separation from the batter and  each other. 
  • Team roster for the game will be posted outside the dugout area. 
  • Whoever picks up a bat after it is used should pick it up by the BARREL END and return it to the dugout.
  • Every batter coming up to bat should be responsible for sanitizing their hands or the handle of the bat before each use.  More than one person may have touched it, whether it is a league bat or their own. 
  • Start each inning with 3 disinfected balls. Any out of play ball is to be disinfected. 
  • For Wednesday games, any team not playing the current game will be required to move to the out of play area past the  temporary outfield fence or stay in the dome entrance area with proper social distancing and masks on.
  • Any of this can be addressed/updated by the Senior Dome Softball committee to follow the most current guidelines  established by the governor and the MN Department of Health. 

Personal Hygiene: 

  • Most important: Avoid touching your eyes, nose and mouth with unwashed hands. 
  • Cover your mouth and nose – with a tissue, if possible – when coughing or sneezing, then properly discard the tissue in  the trash. 
  • Carry hand sanitizer in your bat bag at all times, and use it frequently. 
  • Avoid close contact with anyone else who is coughing or sneezing, or who is otherwise sick. People who exhibit COVID-19  symptoms will be asked to leave the dome. 
  • Wash your hands often using soap and hot water for at least 20 seconds each time. If soap and water are not available,  use an alcohol-based sanitizer that contains at least 60% alcohol. 

General Information

Players  and Play

Dome play is open to men 50 and over, women 40 and over.  Pay to Play.  See payment information below. 

Drafted competitive games will be on Wednesdays and pickup/practice games will be on Mondays and Fridays.


We will only allow a MAX of 15 defensive players  (P, C, 4 IF, 4 rovers - LFR, LCFR, RCFR, RFR, 5 OF - LF, LCF, CF, RCF, RF) on the field and everyone bats for Monday and Friday games.  No over shifts, no rovers can go deep as an outfielder and no rovers can move inside the deepest infielder to fill a gap.  This will allow the not so strong hitters a fair chance to get hits.  There will be a MAX of 12 defensive fielders on the Wednesday games, but everyone bats.

Monday and Friday games will have balanced teams picked by one of the coordinators.  

Wednesday details are: TBD.

Dome rules apply, with ceiling and walls in play, 300 foot fence, (please help set up and take down).  Field coordinators (see Contacts page) will accept Dome compliments, address issues, and have final ruling on all disputes.
