Christian v. Gardner

After his 2-3,  2B, 2 RBI, and SB line on Wednesday, Justin Christian proved he deserve to be starting ahead of Brett Gardner in LF. Both players bring speed and defense to the team, but the real difference is Christian can at least hit a lick. In 21 ABs Christian percentages are .286/.375/.381 while Gardners are .161/.238/.179 in 56 ABs. Gardner only has 3 more hits than Christian in 35 extra ABs. Furthermore Gardner only has 2 more SBs with five, and would only be one more if Christian did not trip attempting to steal third in a pinch run situation in the ninth against the A's (he had a great jump). 

So if both players can run and field, but only one of them can hit for a decent average plus has the ability to hit a home run in a little league park isn't the choice obvious of who should play?
