Starting pitcher George Kirby of the Seattle Mariners has been voted the American League Rookie of the Month for August, and outfielder Michael Harris II of the Atlanta Braves has been voted the National League Rookie of the Month for August.

Kirby earned his first career monthly award and is Seattle’s second rookie winner this season (third time), joining his All-Star teammate Julio Rodríguez (May and June). This marks the first time since Ichiro’s historic 2001 campaign that the Mariners had three Rookie of the Month honors in the same season. Harris received his second Rookie of the Month Award (also June) and represents Atlanta’s third consecutive rookie winner, following his teammate Spencer Strider. This marks 
the first time since Craig Kimbrel (June & August) and Freddie Freeman (July) in 2011 that the Braves had three consecutive Rookie of the Month winners.

• Made five starts for the Mariners, compiling a perfect 4-0 record to go along with a 2.15 ERA. Logged 34 strikeouts while permitting three walks and 30 hits over 29.1 innings pitched.
• Has begun his Major League career with 19 consecutive starts with at least 4.0 innings pitched while not allowing more than a single walk in any outing. That is the longest such streak to begin a career in MLB history.
• The New York native became the first hurler in history to post a strikeout-to-walk ratio north of 7.50 with a minimum of 100 innings pitched across his first 19 career appearances.
• Kirby’s 7.64 strikeout-to-walk ratio on the season ranks first among AL starters and second across all Major League starters, trailing only Aaron Nola’s 8.64 mark.
