Caissie went 0-for-3 with a strikeout in Sunday's loss to the Giants.
The 23-year-old outfielder has gone 19 straight games without a home run, a slump that has seen him manage just a .164/.217/.236 slash line with five RBI and a brutal 48.3 percent strikeout rate. With Esteury Ruiz off the IL, Caissie could begin to see his playing time slip until he figures out big-league pitching.
