When the Clinton LumberKings start the second half of their season Thursday, they will do so with a new manager.

Their parent club, the Seattle Mariners, announced late Sunday that Pat Shine was removed as Clinton’s skipper, and former Chicago Cubs farmhand David Macias will manage the LumberKings the rest of the season.

Macias had been serving as Seattle’s player and staff systems coordinator. He played four seasons in the Cubs’ farm system, including part of two with the Peoria Chiefs. He batted .246 with 1 HR and 30 RBI in 98 Midwest League games (92 in 2009 and 6 in 2011).

Shine’s last game as manager was Clinton’s 16-3 loss to the Cedar Rapids Kernels on Sunday. Shine was scheduled to manage the Western Division team in this week’s Midwest League All-Star Game, but presumably (because Clinton is providing the entire Western Division coaching staff) Macias will helm the team instead.

The LumberKings finished the first half with a 31-36 record, eight games behind the first-place Kane County Cougars, and fifth out of eight Western Division teams.
