Major League Baseball on Tuesday selected a pair of players who took the sport by storm, Houston’s Yordan Alvarez and Cincinnati’s Aristides Aquino, as the American and National League Rookies of the Month, respectively, for August.

Alvarez, 22, is showing no signs of slowing down after socking big league pitching immediately upon his debut in June. The designated hitter slashed .309/.425/.670 in the third month of his career, clubbing nine homers and driving in 26 runs. All of those marks except Alvarez’s average topped AL rookies (min. 100 plate appearances), helping him solidify his standing as the Junior Circuit’s front-runner for Rookie of the Year. Alvarez has taken home AL Rookie of the Month honors in June, July and August, making him the first rookie to claim the monthly award three times in a season since Yankees star Aaron Judge in 2017. Indeed, Alvarez has stood out beyond freshman players; his 181 weighted runs created plus is MLB’s third-best mark since he debuted June 9.

The 25-year-old Aquino set numerous records en route to becoming the fastest Major Leaguer to reach 10 home runs (and subsequently 15 on Monday). The outfielder received just one at-bat in his first cup of coffee with Cincinnati last year, but he made the absolute most of his second opportunity, homering approximately once every seven at-bats over his first full month as a big leaguer. Aquino slashed .320/.391/.767 in August, knocking in a sport-topping 33 runs to go with those 14 homers that tied Hall of Famer Frank Robinson (August 1962) and Greg Vaughn (September 1999) for Cincinnati’s franchise record by any player -- rookie or veteran -- in a calendar month. Aquino’s 14 round-trippers also set an NL record for rookies in any calendar month. He homered in three consecutive innings against the Cubs on Aug. 10, his 10th career game.
