 Biographical Information
Jakub Sládek was a Czech minor leaguer.
A member of the Czech junior national team, Sladek hit .200/.267/.273 for the Tegola Titans in Extraliga play in 2007. He signed that year with the Philadelphia Phillies. He began 2008 with the Regensburg Legionäre in Bundesliga, backing up Alexander Lauterbach at first base, going just 1 for 7 with a walk and not appearing again. Playing for the Czechs in the 2008 World Junior Championship, Jakub was just 4 for 23 with 2 walks and 11 strikeouts, but showed good power as his hits were a single, two doubles and a home run for a .391 slugging percentage.
Sládek made his pro debut with the 2009 GCL Phillies, going 1 for 2 on June 23 against the GCL Blue Jays. For the season, he went 3 for 16 with 3 walks and 8 strikeouts. That would be his only experience in the minors. In the 2009 Baseball World Cup, he made his debut for the Czech national team, going 0 for 3 with two strikeouts. In 2010, he hit .275/.383/.461 for Kotlářka Praha. He tied for third in the Extraliga with four home runs (one shy of Martin Střítecký and Martin Schneider).
In the 2010 European Championship, Jakub hit .267/.313/.400 as the main Czech DH; he also backed up veteran Pavel Budský at 1B. He had three of his four hits in a rout of Belgium, getting 3 doubles, 2 runs, a walk and 3 RBI that day. He had the same role in the 2010 Intercontinental Cup, batting .333/.350/.333; his four RBI tied Budský for the team lead and he was third in average behind Budský and Matěj Hejma, two fellow former minor leaguers.
Sládek saw limited action (presumably due to injury) with the 2011 Praha club, hitting .326/.446/.543 with 13 runs in 15 games. In '12, he was 6 for 12 with two doubles, a homer and five walks in his brief Extraliga action. He was back with the Czech squad for the 2012 European Championship, hitting .267 again (this time with a .353 OBP and .400 SLG). He came up big in the 5th/6th place contest. With the Czechs down 2-1 in the bottom of the 8th, he pinch-hit for Michal Ondráček and doubled off ex-Mariners farmhand Christian Staehely to score Petr Čech with the tying run; the Czechs won, 3-2. In the 2013 World Baseball Classic Qualifiers, Jakub batted 6th and was DH in both games for the Czech Republic. He struck out against Germany's Mike Bolsenbroek his first time up, then walked and came around to score. In the other game, he was retired twice (once by whiff) by Britain's Jake Esch before Budský pinch-hit for him.
