San Francisco Giants starting pitcher Mark Gardner reacts after making a balk to first base allowing Arizona Diamondbacks Travis Lee to advance to second base in the fifth inning in Phoenix, April 16. Gardner was replaced in the fifth by former Diamondbacks pitcher Alan Embree after he gave up seven runs on nine hits, two of which were two run home runs by the Diamondbacks who lead the league with 24 team home runs.
