The case of compromised Houston Astros player intel is a federal investigation, not a baseball probe, says MLB Commissioner Rob Manfred.

That doesn’t mean he can’t hand down penalties as more information comes to light about whether St. Louis Cardinals employees hacked into a personnel database belonging to the Astros.

For decades, baseball’s leadership has handed out discipline to players and management figures for all sorts of reasons. But corporate espionage via computer is a fairly new threat to the game’s integrity, far different from offenses such as stealing pitching signs or using pine tar. There’s no real precedent that might indicate how baseball will handle this matter, and for now, Manfred seems content to let the criminal investigation lead the way.

Major League Baseball said it will evaluate additional steps once federal law enforcement officials complete their investigation. A person familiar with the investigation has told the AP that federal authorities are looking at whether the Cardinals were to blame for what Major League Baseball called a “breach” of the Astros database.

NATIONALS: Bryce Harper’s strained left hamstring kept him out of Friday’s game against Pittsburgh, which came as no surprise after his nasty spill in the outfield less than 24 hours earlier.

Manager Matt Williams opted against placing the two-time All-Star outfielder on the disabled list but didn’t rule out the possibility of ultimately making that move to ensure the long-term health of the team’s best hitter.

RANGERS: Texas sent right-hander Anthony Ranaudo back to Triple-A Round Rock, a day after he delivered 62/3 scoreless innings in a spot start against the Dodgers on Thursday.

INDIANS: Cleveland agreed to a minor league contract with left-hander Brady Aiken, its first-round pick in this year’s draft. Cleveland took a gamble on the 18-year-old, who is recovering from Tommy John surgery and won’t pitch until 2016.

DODGERS: The suspension of infielder Erisbel Arruebarrena was cut to 30 days and he is to report Friday to the team’s complex in Glendale, Arizona.

Arruebarrena was suspended by the Dodgers for the rest of the season on May 21 for what the team said was “repeated failures to comply with his contract.” His lawyer, Jay Reisinger, said Friday an appeal had been filed but the matter has been settled.

TWINS: The team released injured outfielder Jordan Schafer, its opening day center fielder.
