Infield Bases

Portable Base Set for Adult Softball Rec Games

The Jaypro Rubber Throw Down Style Complete Infield Set (Set of 5) is the pick most rec coordinators reach for when they need a portable base set for adult softball rec games that goes down fast and packs up just as quickly. The five pieces are three bases, a home plate and a pitching rubber in flexible, washable rubber. Because these bases sit on top of the ground instead of anchoring into it, they work on grass, dirt, turf or gym floors, indoor or outdoor. That makes them a practical option for co-ed softball leagues, multi-field tournaments, or facilities that reset the same patch of turf for several sports in a single day, and the most budget-friendly way to get a full infield ready for play without any drilling or ground anchors. If you only need to replace the plate on a permanent field, our home plates collection has Jaypro anchor-mount, spike-mount and Bury-All styles.

Rubber Throw-Down Bases

We carry two Jaypro throw-down options. The BB-50 complete infield above includes its own home plate and pitching rubber. The BB-350 is a set of three white bases, each 13-1/2 in. square and 1/2 in. thick, in heavy-duty molded rubber with a waffle bottom; no anchors are required because the bases lay on the playing surface. To complete a BB-350 diamond, Jaypro makes the HP-300 rubber throw down home plate for use with this set. Throw-down bases are built for portability: for a field that stays set up all season, choose an anchored style below.

Heavy Duty Softball Bases: Comparing the Anchored Styles

For a field that stays set up, JoySportStore stocks four anchored Jaypro base styles, each sold as a Set of 3 in white. All four come in the 15 in. L x 15 in. W x 3 in. H footprint, and the Pro-Style Hollywood is also made in 18 in. x 18 in. x 3 in.:

• Economy (BB-100): foam-filled bases with heavy-duty quilted covers, held by 2 nylon straps and 2 steel anchors per base; made in the USA.
• Flex Style (BB-200): shock-absorbing bases that compress on impact, for recreational or competition play; 3 anchors and three 1-1/2 in. solid rubber plugs included.
• Breakaway Style (BB-700): three quick-release bases that disengage upon impact; Jaypro lists the set as fully compliant with Little League Rule 1.06.
• Pro-Style Hollywood 15 in. (BB-500): pebble-embossed, UV-resistant heavy-duty molded rubber with beveled edges on a rust-proof welded stanchion pan; 6 in. stanchions fit 1-1/2 in. base anchors, and 3 anchors and 3 plugs are included.
• Pro-Style Hollywood 18 in. (BB-800): the same Hollywood style in 18 in. x 18 in. x 3 in., with 3 anchors and three 1-1/2 in. solid rubber plugs.

If your search brought you here looking for heavy duty softball bases that can take a full rec or adult league season of sliding and cleats, any of the anchored styles will hold up better than a throw-down set left in place long-term; the throw-down rubber bases are designed for portability first, not for staying anchored under repeated hard slides.

Double First Base: Safety Base for Softball and Baseball

A double first base is a 30 in. x 15 in. base split into two halves: on the Jaypro BB-400, a white half sits in fair territory for the fielder and an orange half sits in foul territory for the runner, which separates the two players at the bag and reduces collision risk. Jaypro rates the BB-400 as meeting or exceeding safety guidelines for youth and recreational softball leagues. Four versions are in stock, all 30 in. L x 15 in. W x 3 in. H:

• Economy (BB-150): foam-filled with a nylon quilted cover, secured with straps and 3 spikes.
• Flex Style (BB-400): compresses on impact; 2 anchors and two 1-1/2 in. solid rubber plugs included.
• Pro-Style Hollywood in green/white (BB-650GR) or orange/white (BB-650OR): the BB-500 molded rubber and stanchion pan construction, with 2 BB-ANCHOR anchors and 2 BB-PLUG plugs.

To outfit a whole infield at once, the BB-600GR and BB-600OR base sets pair a Pro-Style Hollywood double first base with two 15 in. x 15 in. x 3 in. single bases, 4 ground anchors and 4 rubber plugs. Both Hollywood double first base versions are listed by Jaypro as suitable for both baseball and softball.

Sizes, Materials & What Fits Your Field

Most single bases here measure 15 in. x 15 in. x 3 in., which Jaypro describes as official size for its BB-100 Economy and BB-500 Hollywood sets. Major League Baseball uses a larger bag: MLB Official Baseball Rules 2.03 calls for first, second and third base bags 18 inches square and 3 to 5 inches thick, and the 18 in. x 18 in. x 3 in. Pro-Style Hollywood BB-800 is built to that size. Throw-down bases are thinner (the BB-350 is 1/2 in.) because they lay on the surface. When picking a size, match your current bases if you are replacing part of a set, and check the rulebook your league plays under, since youth, high school and softball associations set their own base size. For full diamond layouts by level, see our guide to baseball field dimensions by age.

Base Anchors, Plugs & Replacement Parts

Anchored bases sit on stanchions that drop into a ground anchor. The BB-ANCHOR is a single 1-1/2 in. base anchor for adding or replacing an anchor point. When the bases come off, the BB-PLUG 1-1/2 in. square rubber plug fills the anchor; Jaypro lists it for BB-ANCHOR and BB-ANCHOR150 anchors and for the BB-200, BB-400, BB-500 and BB-700 sets. For fields with mixed sleeve sizes, the Big League Series plug (BB-BLBP) fits both 1-1/2 in. and 1-3/4 in. sleeves (order 3 for a complete set). The BB-DIGOUT dig-out tool clears dirt and debris from base sleeves so bases go in and out cleanly, and the BB-RAP is a replacement stanchion for the Flex Style BB-200 bases and BB-400 double first base.

Multi-Use Fields and Kickball

Shoppers landing on this page searching for kickball bases or bases for softball field use are often outfitting the same multi-purpose field for more than one sport. The Jaypro rubber throw-down sets are the most flexible option here: because they require no ground anchors, they can be placed for a kickball game, a softball scrimmage or a gym-class setup and then picked up and stored between uses. They are not kickball-specific products, but the no-anchor design makes them workable for programs running multiple games on the same field or court.

Base Carts for Storage and Transport

Facilities managing heavy pro bases can use the Jaypro StackMaster Professional Base Cart to move and store bases and receptacles between fields. It has a heavy-duty square steel frame, pneumatic tires and a black powder-coated finish, positions bases for easy cleaning and touch-up, and is recommended by Jaypro for collegiate, high school and town programs. It cannot be used with Flex Style bases (BB-200) or the Flex double first base (BB-400). The BCARTSET package combines the cart with a BB-500 Pro-Style Hollywood base set.
