Flores is out of the lineup for Sunday's game against the Angels.
The Pirates will go with Henry Davis behind the plate Sunday while Flores rests for the second time in the series. Though he's maintained a solid .794 OPS over 105 plate appearances with the Pirates on the season, Flores has fallen into a bit of cold spell lately, going 4-for-30 with a 28.1 percent strikeout rate over his last nine games.
