8:10pm: Brown gets a $1.45MM bonus, according to Jim Callis of Baseball America (on Twitter).
3:46pm: The Giants agreed to sign first-round pick Gary Brown for about $1.3MM, according to Yahoo's Kendall Rogers (on Twitter). The Giants, who selected the 21-year-old outfielder 24th overall in this year's draft, appear to be paying him close to slot money. Last year, the Angels paid Randal Grichuk slot money ($1.242MM) after drafting him 24th overall. The A's selected Brown in the 12th round of the 2007 draft, but he went on to star at Cal State Fullerton instead of signing.
Now that the Giants have agreed to sign Brown, 15 first-round picks have yet to come to terms with the clubs that drafted them.
