The Rays signed No. 31 overall pick Justin O'Conner today for $1.025 million. A catcher from Cowan High (Muncie, Ind.), O'Conner becomes the fourth of the 32 first-round picks this year to sign.

O'Conner is the first of the four signed first-rounders to receive a larger bonus than the corresponding pick in the 2009 draft. Last year's No. 31 choice, Cubs outfielder Brett Jackson, signed for $972,000.
