About Shawn Sedlacek

Born 1977. Shawn Sedlacek is an American baseball player.

Shawn Patrick Sedlacek (born June 29, 1977) is an American former professional baseball pitcher. He played part of one season in Major League Baseball (MLB), primarily as a starting pitcher, for the Kansas City Royals in 2002. Sedlacek threw a four-seam fastball, a two-seam fastball, a changeup, a slider, and a curveball.

Born in Cedar Rapids, Iowa, Sedlacek attended Iowa State University, leading the team with 65 strikeouts and 77 innings pitched as a senior before getting selected by the Royals in the 1998 MLB draft. Initially expected to be a relief pitcher, he became a starting pitcher during his first season due to injuries to other starters, and he would finish among the leaders in the minor leagues he pitched in over the next few years. The Royals called him up in June 2002 following injuries to Jeremy Affeldt and Paul Byrd, and he debuted for them on June 18. Sedlacek posted a 3.05 earned run average (ERA) in his first six starts but had a 10.10 ERA in his next eight and was moved to the bullpen in September. After pitching for Kansas City's minor league affiliates in 2003, he left the Royals organization and played for two years in the minors for several other teams and also in the independent Northern League. Remaining in the Kansas City area following his retirement, he is part of Complete Game Baseball, an organization that provides baseball training and fields its own teams.

Early life Shawn Patrick Sedlacek was born on June 29, 1977, to Pat and Arlis Sedlacek in Cedar Rapids, Iowa. He was one of two children, the other being sister Sara. Shawn played Babe Ruth League baseball while growing up, getting instructed on pitching from local resident Gary Ray. Sedlacek continued to play baseball at Kennedy High School, graduating in 1994.

Sedlacek attended Indian Hills Community College for two years, then transferred to Iowa State University, which offered him a baseball scholarship. As a senior, he overcame an 0–4 start to post a 6–6 record for the Cyclones. His fastball velocity rose from to the low-to-mid 90 miles per hour (145 km/h) range during the year, and he led Iowa State pitchers with 65 strikeouts and 77 innings pitched.

Professional career

Minor league career, part 1 After graduating from Iowa State in 1998, Sedlacek was drafted by the Kansas City Royals in the 14th round of the 1998 Major League Baseball (MLB) draft. He began his minor league career pitching for the Spokane Indians of the Single-A (short season) Northwest League. Manager Jeff Garber expected Sedlacek to pitch out of the bullpen, but injuries to two of Spokane's starting pitchers led to Sedlacek becoming the team's best starter. In 16 games (13 starts), he had a 9–2 record (tying for the league lead in wins with Chris Mears), a 3.45 earned run average (ERA) (fifth), 62 strikeouts, and 18 walks in 86 innings pitched (third behind Mears's and Jeff Hundley's ).

In 1999, Sedlacek pitched for the Wilmington Blue Rocks of the Single-A advanced Carolina League. He missed two months with a broken thumb suffered in May. In 17 starts, he had a 4–6 record, a 5.28 ERA, 69 strikeouts, and 26 walks in 92 innings pitched. He was promoted to the Wichita Wranglers of the Double-A Texas League in 2000. In 35 games, he had a 3.66 ERA, 81 strikeouts, and 43 walks in innings pitched (10th in the league). Despite only making 16 starts, he led the league with 15 wins.

Despite his successful 2000 season, Sedlacek began 2001 with the Wranglers. "I'm approaching this as a whole new season," he said. In 14 starts with Wichita, he had a 6–7 record, a 3.63 ERA, 66 strikeouts, and 14 walks in innings. During the season, he was promoted to the Omaha Golden Spikes of the Triple-A Pacific Coast League (PCL). In 14 games (13 starts) for Omaha, he had a 5–4 record, a 5.00 ERA, 44 strikeouts, and 22 walks in 81 innings. He made only three starts for Wichita before getting promoted to Omaha (now known as the Royals) on April 20. In 11 games (all starts) for Omaha, he had a 6–5 record, a 3.70 ERA, and 66 strikeouts in innings pitched. He made his major league debut on June 18, getting a no-decision in a 5-4 loss to the Montreal Expos. "This kid was throwing real well...he did a great job," said Royals manager Tony Peña. Five days later, in his second start, he gave up one run in six innings but took a no-decision in a 5–4 loss to the New York Mets. On July 4, Sedlacek had one of the best starts of his career; he allowed one run in a career-high seven innings, receiving a no-decision in a 3–2 loss to the Oakland Athletics. His first career win came on July 15, in the first game of a doubleheader, when he gave up three runs in six innings as the Royals defeated the Texas Rangers 8–6. Five days later, he tied his career high with seven innings pitched and allowed just two runs, but he received a no decision in a 5–3 loss to the Cleveland Indians. Through six starts, he had a 1–0 record and a 3.05 ERA. Sedlacek attributed his struggles to fatigue, as he was in the process of setting a new career high in innings pitched (183). He got off to an 0–6 start, not winning a game until May 17, when he allowed three runs (one earned) over innings in a 7–3 victory over the Iowa Cubs. In 27 games (13 starts) for Omaha, he had a 4–11 record, a 6.45 ERA, and 52 strikeouts in innings pitched. He also made five starts for Wichita, posting a 1–2 record and a 5.60 ERA. In 17 games (all starts), he had a 6–5 record, a 3.38 ERA, and 92 strikeouts in innings pitched. After the season, he retired. While with the Royals, he formed a friendship with Mike Boddicker, a former MLB pitcher who also was not a hard thrower in his career. Boddicker advised him to throw pitches high and inside of the strike zone, as well as low and away. He also advised Sedlacek to try to fool the hitters by making them expect a different pitch than the one he would actually throw. Initially beginning a career in financial services in retirement, Sedlacek wanted to remain active in baseball. In 2006, he started Sed Sports, Inc. Originally, the organization offered pitching lessons to amateurs and professionals in the Kansas City metro area. Sed Sports began fielding its own teams in 2012. The next year, Sedlacek partnered with Todd Sears and Matt Williams. They changed the name of the organization to Complete Game Baseball, which has since grown to field 25 teams.
