The A's bestowed their highest Minor League honors on right-hander Trevor Cahill and first baseman Chris Carter on Thursday, naming them their Organizational Pitcher and Player of the Year, respectively

Cahill, 20, is a repeat winner, having also received the award in 2007.

The A's second-round selection in the 2006 First-Year Player Draft, Cahill pitched for Class A Stockton and Double-A Midland this season, posting a combined record of 11-5 with a 2.61 ERA in 21 games (19 starts) while striking out 136 batters in 124 1/3 innings and holding opponents to a .179 batting average.

Baseball America named Cahill the top prospect in the Class A California League, where he went 5-4 with a 2.78 ERA in 14 appearances on his way to being named a Cal League midseason All-Star before his promotion to Midland.

A 6-foot-3, 195-pound native of Oceanside, Calif., Cahill dominated Double-A competition, going 6-1 with a 2.19 ERA in seven outings for the RockHounds.

Cahill, who likely will get a look at big league Spring Training in February, threw one scoreless inning in the All-Star Futures Game at Yankee Stadium on July 13, and he posted a 2.25 ERA in two starts for Team USA at the Beijing Olympic Games, allowing six hits and two earned runs over eight innings.

Carter, 21, enjoyed a breakout season at Stockton, leading the Cal League with 39 home runs and 104 RBIs. He batted .259 with 101 runs scored, a .361 on-base percentage and .569 slugging percentage, playing first and third base and designated hitter.

A 6-foot-4, 210-pound slugger acquired in the offseason deal that sent Dan Haren to Arizona, Carter also hit five homers and drove in 18 runs in 12 playoff games, helping Stockton to the Cal League crown. In the Sept. 14 title game, Carter went 3-for-5 with a grand slam, a solo home run and five RBIs in the Ports' 9-3 win over Lancaster.

After leading the league in homers, RBIs, runs scored, slugging percentage and total bases, Carter was named the 2008 California League Rookie of the Year. His 39 regular-season home runs tied for second most in all of Minor League baseball this year.
