There are several ABS challenge stat updates now available:

• Challenge stats on player pages

Challenge stats for individual players are now displayed on the Baseball Savant player pages, under the "ABS" tab within the Statcast section.

Here's an example of Mike Trout's batter challenge stats and Cal Raleigh's catcher challenge stats:

Note: Catchers have separate sections for their challenges as a batter and as a fielder.

• Team-level challenge summaries

Navigating to the "Team Summary" section of the Statcast ABS leaderboard shows a team's overall challenge statistics -- with combined results for batters and fielders.

• Challenge run value added stats

On the ABS leaderboard, in addition to total challenges made, won and lost, there is an alternate view showing the run value added from challenges.

To see the full run value view, use the dropdown menu above the leaderboard table to change "# Challenges" to "Run Values."

For example: See the batter ABS run value leaders here or the catcher ABS run value leaders here.

• "Reasonable challenges"

New stats for a player's "reasonable challenges" are available on the Statcast ABS leaderboard. (See batters here, for example.)

A "reasonable challenge" opportunity happens when at least one of the following three things is true:

1. The original ball/strike call was incorrect ...
2. The pitch is within 3 inches of the strike zone edge and an overturn would gain at least +.3 runs ... OR
3. The pitch carries an expected challenge rate of at least 20%

• ABS challenge documentation

An ABS Metrics Documentation page is now available containing definitions of various challenge-related Statcast metrics.
