Jack Flaherty Autographs
Jack Flaherty is a highly-touted professional baseball player who currently plays as a pitcher for the St. Louis Cardinals of the Major League Baseball (MLB). Born in California on October 15, 1995, Flaherty played baseball from a young age and attended Harvard-Westlake High School where he excelled. He was drafted by the Cardinals in the first round of the 2014 MLB draft and started his professional baseball career with the Gulf Coast League Cardinals.
Flaherty's career quickly rose as he advanced to the Major Leagues in 2017. In his rookie season, he performed impressively, posting a 3.34 earned run average (ERA) in 21 starts for the Cardinals. He continued to improve in the 2018 season, leading the Cardinals in strikeouts and becoming a key part of their starting rotation. He was awarded the National League player of the week award twice and was named the organization's Minor League Pitcher of the Year.
In 2019, Flaherty had his best season yet, earning his first All-Star nod while posting a 2.75 ERA and leading the Major Leagues in second-half wins. He also became the youngest pitcher in Cardinals' history to start a playoff game. With his impressive performance and continued growth, it is no surprise that Flaherty is considered one of the top young pitchers in the league today.
