Hard-throwing rookie Jacob Misiorowski is a National League All-Star replacement, giving the Milwaukee Brewers right-hander a chance to break Paul Skenes’ record for the fewest big league appearances before playing in the Midsummer Classic.

Misiorowski was named Friday night to replace Chicago Cubs lefty Matthew Boyd, who will be unavailable for the All-Star Game on Tuesday night in Atlanta because he is scheduled to start Saturday at the New York Yankees.

The 23-year-old Misiorowski has made just five starts for the Brewers, going 4-1 with a 2.81 ERA while averaging 99.3 mph on his fastball, with 89 pitches that have reached 100 mph.

If he pitches at Truist Park, Misiorowski will make it consecutive years for a player to set the mark for fewest big league games before an All-Star showing.

Skenes, the Pittsburgh Pirates right-hander getting ready for his second All-Star appearance, had made 11 starts in the majors when he was chosen as the NL starter for last year’s All-Star Game at Texas. He pitched a scoreless inning.

Misiorowski is the 30th first-time All-Star and 16th replacement this year. There are now 80 total All-Stars.

Carlos Rodón, Carlos Estévez and Casey Mize were named replacement pitchers on the AL roster.

The New York Yankees’ Rodón, an All-Star for the third time in five seasons, will replace teammate Max Fried. for Tuesday’s game in Atlanta. Fried will be unavailable because he is scheduled to start Saturday against the Chicago Cubs.

The Kansas City Royals’ Estévez replaces Texas’ Jacob deGrom, who is scheduled to start at Houston on Saturday.

Mize takes the spot held by Boston’s Garrett Crochet, who is scheduled to start Saturday against Tampa Bay. Mize gives the Tigers six All-Stars, most of any team and tied for the franchise record.

Royals third baseman Maikel Garcia will replace Tampa Bay’s Brandon Lowe, who has left oblique tightness. The additions of Estévez and Garcia give the Royals four All-Stars.

The Mariners announced center fielder Julio Rodríguez will not participate, and he was replaced by teammate Randy Arozarena. Rodríguez had been voted onto the AL roster via the players’ ballot. The Mariners, who have five All-Stars, said Rodriguez will use the break to “recuperate, rest and prepare for the second half.”
