The Diamondbacks have agreed to terms with righthander Felipe Perez, the highest-ranking undrafted player on our predraft BA 500 rankings, on a $400,000 bonus.

Any eligible player who goes undrafted is eligible to sign with any team as a free agent until he attends class at a junior college or college. Per baseball's new draft rules, nondrafted free agents are treated similarly to players selected after the 10th round. Any bonus money in excess of $100,000 counts against the team's bonus pool for the first 10 rounds.

The Diamondbacks saved $113,500 against their $3,818,300 pool this summer, and could spend up to $404,415 on Perez without exceeding their total allotment by more than 5 percent, which would have cost them their 2013 first-round pick. Arizona will have to pay a 75-percent tax on their $186,500 overage, which comes to $139,875. Perez's bonus is more than what all but two of the team's draft picks received this year.

Perez attended Fairmont Prep in Anaheim and pitched this summer for the Cowlitz Black Bears in the West Coast League, a summer collegiate circuit. A UCLA recruit, he saw his stuff improve a little bit from the spring. He touched 93 mph with his fastball and showed three pitches that could be average to plus at some point.
