On April 12, 2008 — Mike Hartley becomes perhaps the first former major leaguer to play in the Bundesliga. The 46-year-old player-coach throws two relief innings, walking two, striking out two and allowing one unearned run in a 10 – 8 win for the Heidenheim Heideköpfe over the Mainz Athletics. Simon Gühring, a former Brewers minor leaguer, gets 3 hits to lead Heidenheim’s offense.
