After his only season as the Cardinals hitting coach in 2010, Mark McGwire is undecided about his coaching future with the team. Manager Tony La Russa said on a press conference on Tuesday night that McGwire might decide if he’ll return in 2011 by Thursday.

Joe Strauss from the St. Louis Post-Dispatch learned from the press conference with La Russa that McGwire is “really torn” regarding his future with St. Louis. The manager cited family concerns as McGwire’s deciding factor. He recently rejoined his wife Stephanie and family in California.

McGwire agreed to be the team’s hitting coach in October 2009, and according to Strauss, he has been asked back. While the team’s batting average remained the same between 2009 and 2010 at .263, their rank among the 16 National League teams increased from 4th best to 2nd best.
