• Right-handed reliever Dale Thayer was back with the Padres after taking paternity leave to be with his wife in California for the birth of his fourth daughter, Layla Kate, on Monday. San Diego optioned right-handed reliever Kevin Quackenbush to Triple-A El Paso.
• Major League Baseball announced Wednesday that a scoring change was made from the Padres-Nationals contest on April 26, changing a hit by Jayson Werth to an error on second baseman Jedd Gyorko (his fifth of the season). That results in the starting pitcher for San Diego in that game, Andrew Cashner, having his earned run average lowered to 2.35 (15 ER in 57 1/3 IP) after two earned runs were subtracted from his total for the season.
• Headley's go-ahead solo home run off Reds closer Aroldis Chapman in the ninth inning of Tuesday night's 2-1 Padres win came on a 99.4 mph fastball. That was the hardest-thrown pitch hit for a homer in the Majors this season, and the hardest-thrown pitch ever hit for a home run by a Padres player since data began being tracked in 2008.
The previous fastest pitch hit by a Padres player for a homer was a 98.1 mph offering -- also from Chapman -- hit by Chris Denorfia on July 29, 2013.
