Pitcher Luke Weaver was selected by the Toronto Blue Jays in the 19th round of the 2011 amateur draft but did not sign, opting to attend Florida State University instead. He was then taken by the St. Louis Cardinals and scout Ty Boyles in the first round of the 2014 amateur draft with the 27th overall pick. He signed for $1.843 million and made his pro debut that summer with the GCL Cardinals.
He first made it to the majors late in the 2016 season and went 1-4, 5.79 in 9 games. He had a good half-season in the majors in 2017, with a 7-2 record and a 3.88 ERA in 13 games (10 starts) and 60 1/3 innings. This gave the Cardinals hope that he would be one of their top starting pitchers in 2018, but he regressed, as his ERA rose to 4.95 in 30 games, and his record was 7-11. He gave up 150 hits in 136 1/3 innings, but did strike out 121 batters. After the season, he was traded to the Arizona Diamondbacks alongside fellow youngsters Carson Kelly and Andy Young and a Compensation Round B pick in the 2019 amateur draft in return for 1B Paul Goldschmidt.
