What happened: Pittsburgh Pirates rookie Konnor Griffin stole home in the first inning against the Washington Nationals on July 4, part of a two-steal frame to open the game. The steal of home pushed him to 19-for-20 on stolen-base attempts in his rookie season. Washington went on to win the game 9-5.
Why it matters: Griffin's baserunning has become one of the most reliable parts of his rookie campaign, and a straight steal of home is among the rarest plays in the sport. It is an encouraging sign for the same Konnor Griffin who began a rehab assignment with Double-A Altoona in late June, showing his speed has carried over since rejoining the big-league club.
By the numbers: Griffin is 19-for-20 on stolen-base attempts this season, a 95 percent success rate, with two of those steals coming in the first inning of Saturday's game — including home. The Nationals won 9-5 and have won three straight.
What to watch: Watch whether Griffin keeps the green light on the bases as the Pirates continue their series in Washington this holiday weekend.
