Milwaukee Brewers manager Ron Roenicke's willingness to replace the struggling Casey McGehee with Jerry Hairston Jr. at third base heading into the National League Divisional Series has helped add some juice to the bottom third of the lineup.

Don't look for any personnel changes at second base heading into Game 5 with the Arizona Diamondbacks, however.

Roenicke said Thursday that despite Rickie Weeks' struggles to this point - he's 1 for 15 with one run batted in and a walk - he's not entertaining any thoughts of sitting the all-star down.

Weeks continues to play at less than 100% as he recovers from the severe left-ankle sprain he suffered in late July. But unless the ankle hampers him to the point where he's not able to perform at all, Weeks will remain the starter at second for as long as the Brewers' postseason run lasts.
