Michael Wacha
The Cardinals won each of Wacha's first nine starts of 2015 while he credited as the winner in seven of them. With an ERA of 1.87, he became the first Cardinal to start with a 7–0 record since Matt Morris started 8–0 in 2005. He was selected to his first All-Star Game, played at Great American Ball Park in Cincinnati. The Cardinals skipped 10 days between two August starts over concerns about his shoulder. To that point, he was 15–4 with a 2.69 ERA and 1.12 WHIP. In Game 4 of the NLDS against the Cubs on October 12, 2015, Wacha surrendered three home runs in 4 1⁄3 innings in an 8–6 loss. Wacha started 30 games in 2015, in which he was 17–7 with a 3.38 ERA.
Wacha struggled in 2016. He missed over a month due to right shoulder inflammation and finished the season with a 7-7 record in 27 games (24 starts) with a career-high 5.09 ERA and 1.48 WHIP.
In 2017, Wacha stayed healthy the entire season and tied a career high in starts with 30. He finished the season with a 12-9 record and 4.13 ERA, recording a 3.41 ERA at home and a 4.97 ERA on the road.
On June 3, 2018, against the Pirates, Wacha took a no-hitter through eight innings until giving up a lead-off single by Colin Moran in the ninth inning. Nevertheless, the Cardinals won 5–0. On June 21, Wacha was placed on the 10-day disabled list due to a left oblique strain, and did not pitch the remainder of the year. For the 2018 season, Wacha made 15 starts, going 8-2 with a 3.20 ERA.
Wacha began the 2019 season healthy and a member of St. Louis' starting rotation. However, after compiling a 5.59 ERA through nine starts, he was moved to the bullpen at the end of May.
