Manager Davey Johnson moved Danny Espinosa down in the order, from his customary second spot to sixth. Espinosa has been slumping for the past month, party because of bad luck but also because of a high strikeout rate – he has whiffed once every 3.5 plate appearances.

Since the all-star break, while playing every game, Espinosa has gone 19 for 113 with nine walks and one homer, which works out to a .168/.236/.257 slash line. Espinosa is 3 for his last 22 with two walks and seven strikeouts.

In another change, Ian Desmond, who has a .279 on-base percentage this season, will hit leadoff against Reds right-handed start Johnny Cueto, with Rick Ankiel hitting second.
