Homerun Lineup

What is this app?

The Homerun Baseball Ottawa lineup app helps coaches plan and manage baseball game lineups and practices. It runs entirely in your browser — no account, no server, no internet required after the first load. All data is saved locally in your browser.

Getting started in 3 steps:

1. Go to Roster and add your players.
2. Go to Schedule and add your games (and set your team name).
3. Click Open Lineup → on any game in the Schedule, or select a game from the Active game dropdown and switch to Game Lineup.

Use the Practice tab to browse 368 drills and build timed practice plans.

📲 Add to your Home Screen

Install this app so it opens full-screen, without the browser bar — just like a native app.

On iPhone/iPad (Safari):

1. Tap the Share icon in Safari's toolbar.
2. Scroll down and tap Add to Home Screen.
3. Tap Add — the app icon now appears on your Home Screen and opens full-screen, without the browser bar.

On Mac (Safari):

2. Choose Add to Dock.
3. The app now opens from your Dock in its own window, like a native app.

Roster

The Roster tab is where you manage your players for the season.

• Add players with their name, jersey number, and flags.
• Call-up flag: marks players called up from a lower division. The app will warn (but not block) if a call-up is assigned to pitcher or catcher.
• Pitcher / Catcher flags: indicate whether a player is willing to play those positions. Placing an unwilling player at P or C triggers a red hard-flag.
• Reorder (↑↓): sets the default batting-order seed for new games.
• Filter: type in the filter box to narrow by name or jersey number.
• Player stats: click any player's name to see a popover with their season totals — field innings, bench innings, and position breakdown across all saved lineups.

Schedule

The Schedule tab tracks all your games for the season.

• Add games with date, time, opponent, location, home/visitor status, and notes.
• Team name & rules level appear at the top — set these once for the season.
• Result: record the outcome after the game is played. Results are color-coded (W = green, L = red, T = grey). Click the result cell directly to edit inline.
• Notes: click a notes cell to edit it inline — press Enter or click away to save, Escape to cancel.
• Click Open Lineup → on any game to jump directly to its lineup editor.

Game Lineup

The Game Lineup tab is the core of the app. Select an active game first using the dropdown.

Attendance

Mark players as present or absent (OUT). Absent players are removed from the batting order and field grid for this game but stay on the roster. An attendance summary shows how many players are present and whether you have a full field of 9.

Batting Order

Every present player bats in a fixed continuous order. Use the arrows or the slot dropdown to reorder. The batting order persists across all innings.

Auto-generate Lineup

Click Auto-generate Lineup (the large button) to fill the grid automatically. The generator satisfies Little League’s Equal Play rule, respects your team-preference settings, and enforces the pitcher/catcher eligibility gates. Click again for a different arrangement — the generator is randomized.

After auto-generating, an ↩ Undo Generate button appears. Click it to restore the grid to exactly what it was before the generation. The undo snapshot is discarded if you make any manual grid edit or save the lineup.

Position-per-Inning Grid

Rows are present players (in batting order); columns are innings 1–6. Assign each player a position code (P, C, 1B, 2B, 3B, SS, RF, CF, LF) or B for bench each inning. The Field column on the right shows each player's defensive innings count — green means the Equal Play minimum of 2 is met. Cells are color-coded by position type: blue = battery (P/C), amber = infield, green = outfield, grey = bench.

Clear Grid

The Clear Grid button in the toolbar resets all position assignments to blank without changing attendance or batting order. Use this when you want to start fresh with a new arrangement.

Game Settings (Team Preferences)

• Infield innings (min): minimum innings each player should spend in the infield. Default = 1. Not a Little League rule.
• Same position limit (max): maximum innings a player can play the same position. Default = 2. Not a Little League rule.
• Pitcher / Catcher consecutive innings: ask the generator to keep the same pitcher or catcher for multiple consecutive innings.
• Starting Pitcher: optionally lock a specific player at P in inning 1.

Flags & Conflicts

The app highlights problems automatically as you edit the grid:

• Red (hard rule): Little League rule violations — Equal Play, duplicate/empty positions, pitcher/catcher eligibility gates, or unauthorized P/C placement. Resolve before saving.
• Amber (team preference): Your team's configurable conventions — Infield innings minimum or same-position limit.
• Blue (advisory): Non-blocking notices — pitcher returning to the mound, or a call-up at P/C.

Position Counts — season fairness tracker

Tracks how many innings each player has spent at each position — for this game, the previous game, and the full season to date. Useful for ensuring equitable playing time.

Save & Print

Click Save Lineup to commit the current grid to browser storage. Use Print / PDF to get a printable version for game day. The print view includes the game header, batting-order list, and inning grid — all formatted for black-and-white printing.

Practice Planner

The Practice tab gives you access to 368 drills sourced from the Youth Baseball Canada knowledge base.

• Search: type in the search box to find drills by name, skill, or tags.
• Filter by skill: click a skill chip (Hitting, Throwing, Infield, etc.) to narrow the list.
• Filter by intensity: Low / Medium / High — useful for warm-up vs. main work vs. conditioning.
• Filter by age: select an age range to see only age-appropriate drills.
• Drill cards: click any drill card to see the full detail — purpose, setup, coaching cues, execution steps, common faults, and equipment needed.
• Add to plan: click the + button on a drill card to add it to your practice plan. Click again to remove it.
• Reorder drills: use the ↑↓ arrows on plan items to rearrange the order.
• Time budget: the bar shows how much of your session time is used up.
• Skill-Focused Plans: pre-built plans organized by skill — click any plan card to load it instantly.
• Save / Load: save your plan to browser storage and load it later.
• Print / PDF: generates a printable practice plan with timeline, drill details, and coach's notes.

Back up & Restore data

The ⬇ Back up and ⬆ Restore buttons in the top bar let you save and restore all your data — the full roster, schedule, and every saved lineup.

• Back up: downloads a .json file with everything. Use this to back up your data, transfer to another device, or share with an assistant coach.
• Restore: loads data from a previously exported file. This replaces all current data, so the app will ask you to confirm first. Use this to pick up exactly where you left off on a different device or browser.

Because the app stores data in this browser (not a cloud account), backing up regularly is the safest way to avoid losing data.

Little League rules vs. team preferences

The app clearly distinguishes between official Little League rulebook requirements and your team’s configurable preferences. Rules (like Equal Play and pitcher/catcher eligibility) are enforced as hard red flags and cannot be turned off. Team preferences (like the infield minimum) are soft amber flags and are fully configurable in Game Settings. The How flags work section inside the Game Lineup tab has the full details.
