The wife of L.A. Dodgers pitcher J.P. Howell is calling for a changeup -- filing divorce docs after 7 years of marriage ... TMZ Sports has learned.
Howell -- who's in the middle of a 2-year $11 million contract -- married former sports reporter/author Heather Hennessy Howell back in 2009. They were college sweethearts at USC.
But the love story's over ... Heather filed docs in L.A. County Superior Court citing irreconcilable differences.
Seems things soured recently ... they posed for a coupley pic together just last month.
