Orioles CF Adam Jones back in starting lineup
Jones was starting in center field Wednesday night after going to a local hospital for tests a night earlier.
''I feel 100 percent,'' Jones said before taking the field for pregame activity. ''Last night I just didn't feel like myself.''
Jones said doctors found nothing specific.
''I think it was more eliminating a lot of things than anything else,'' said manager Buck Showalter. ''I think a lot of it was dehydration. Sometimes we lose sight of what a challenge physically a baseball season is.''
Showalter said Jones' condition is something he has stayed on top of throughout the day.
''I'll ask him again after batting practice and again before the game. We're ready to go either way.''
Jones has played in 125 of Baltimore's 127 games this season, batting .296 with 22 home runs and a team-leading 77 RBIs.
