When JP France was called up by the Houston Astros in early May, he was brought in to backfill injuries to key Astros pitchers Luis Garcia and Jose Urquidy. At the time, it wasn’t definite how long France would stay with the big-league club. After all, he wasn’t rated as one of the Astros’ top pitching prospects. But now, 3 ½ months later, France has arguably been the steadiest pitcher in the Astros’ starting rotation, and he’s doing his best to contend for the American League Rookie of the Year award.

France, who prepped at Archbishop Shaw High School and played three seasons for Tulane University before transferring to Mississippi State, is in his fifth professional season. He was the 14th- round selection of the Astros in the 2018 MLB Draft.

He wasn’t particularly effective in his first full minor-league season in 2019 with High-A Fayetteville, posting a 4-9 record and 4.31 ERA.

He missed the entire 2020 season when the minor leagues were shut down by COVID. The year’s layoff apparently worked in France’s favor, because he made great strides in 2021 when he finished with a 9-3 record and 3.79 ERA, split between Double-A Corpus Christi and Triple-A Sugarland.

France was back with Sugarland for the 2022 season, where his 34 appearances were split between starter and reliver roles. If he was to make it to the big leagues with the Astros, it wasn’t certain which role he would fill.

Garcia and Urquidy were expected to pick up where they left off in 2022, when they combined with Framber Valdez and Justin Verlander to propel the Astros through the playoffs, ultimately defeating the Philadelphia Phillies in the World Series. Their performances were a big reason the Astros let Verlander go into free agency after the season. Plus, the Astros expected Lance McCullers Jr. to return to the rotation in 2023 after missing most of 2022 due to injury. The prospect of France breaking into the Astros’ starting rotation looked grim. At 28 years old, time was running out for him to get a fair shot with Houston.

Yet, the Astros turned to France when Urquidy and Garcia went down during the first month of this season. Further complicating Houston’s situation was McCullers’ start of the season on the Injured List. France was picked over the Astros’ No. 1 prospect Hunter Brown to backfill the injured pitchers.

It turns out France’s major-league debut on May 7 was a good omen of what he would contribute to the ailing rotation. He threw five shutout inning against the Seattle Mariners, giving up only three hits and a walk.

He’s has been a key factor in Houston’s ability to remain close to AL West Division leader Texas Rangers. He now sports a 9-3 record, with an impressive 2.74 ERA. He is tied with Cleveland’s Tanner Bibee for most wins by a rookie this season. France has won his last seven decisions. Lately, he’s been more effective than Valdez, the team’s No. 1 starter.

Urquidy is back with the Astros and Verlander was re-acquired at the major-league trade deadline. France was temporarily assigned to bullpen duty, but he returned to the rotation on August 12, when he handily defeated the Los Angeles Angels. Now flush with starters, the Astros are considering a 6-man rotation that includes France.

He will have stiff competition for Rookie of the Year honors. Baltimore infielder Gunnar Henderson, Rangers third baseman Josh Jung, Cleveland’s Bibee, and France’s teammate Brown, who was elevated to the Astros shortly after France, have also earned worthy consideration.
