Brewers pitcher Jimmy Nelson was firing on all cylinders in his season debut Sunday, giving up five hits and three walks over 5 2/3 scoreless innings and striking out six in his team's 7-1 victory over the Marlins.

Nelson (1-0) was filling in for the injured Yovani Gallardo, who may be able to make his next scheduled start. If Gallardo is cleared, Nelson will likely be sent back down to Triple-A, where he is 5-1 with a 1.71 ERA, 0.93 WHIP and 58:17 K:BB ratio in 58 innings over nine starts.
