Stratton, the Giants' No. 28 prospect, started and was brilliant, firing three hitless innings and striking out a pair. The 2012 first-round Draft pick issued one walk in the outing, and seven of the 11 outs he recorded came via groundballs.
Johnson (No. 15) followed Stratton and struck out a pair in two innings of work, though he was responsible for the aforementioned two hits and earned run. Gregorio (No. 22) held the Brewers' offense in check with a scoreless sixth inning, and the team's 2014 first-rounder Beede (No. 2) capped the Giants' big day on the mound with a perfect seventh.
• After he struggled last week in his spring debut, Braves No. 12 prospectLucas Sims bounced back with a sharp outing against the Marlins, striking out four of the seven hitters he faced in two scoreless innings against the Marlins.
• Orioles Nos. 11 and 22 prospects Tanner Scott and Oliver Drake combined to strike out five -- all swinging strikeouts -- of the six batters they faced in the eighth and ninth innings, with Scott, who can hit triple digits, striking out the side.
