A's conclude Draft with 20 picks on Day 3

High school, college players split on Wednesday's board

The Oakland A's wrapped up the 2010 First-Year Player Draft on Wednesday, making 20 selections that included 10 college players and 10 prep stars.

The A's selected Bobby Geren in the 36th round -- the son of manager Bob Geren. Geren, who is committed to play at Princeton, is a left-handed-hitting corner infielder from nearby San Ramon Valley High School. Geren batted .213 with a home run and nine RBIs in 24 games for San Ramon Valley this season.

"He's worked hard," the Oakland skipper said. "He's worked as hard as he can in school and baseball. It's something he feels real good about. Obviously, we're proud about what he's done."

Three other managers' sons were selected by their father's organizations on Tuesday, including San Francisco's Brett Bochy, son of Bruce. The White Sox selected Ozney Guillen, son of Ozzie, while the Tigers drafted Patrick Leyland, son of Jim.

Another familiar name came in the 35th round, as Oakland drafted another right-handed pitcher named Andrew Bailey -- this one from Concord University.

In 14 starts (five appearances) this season, Bailey went 5-1 with a 4.82 ERA. He struck out 41 batters in 46 2/3 innings while allowing 57 hits and 19 walks.

Oakland also selected a couple of players with local ties, as 6-foot-4 lefty Louie Lechich, picked in the 42nd round, is from the famed 209 -- Stockton, Calif. Lechich is committed to play baseball at nearby University of California-Berkeley.

In the 44th round, the A's selected Lonnie Kauppila, a shortstop from Burbank (Calif.) High School. Kauppila is a solid defender who hits for a high average, and he is committed to play baseball at Stanford.

To start off Day 3, the A's selected Fresno State signee Aaron Judge, a 6-foot-7, 230-pound third baseman from Linden (Calif.) High School. Judge hit .500 with seven home runs and 32 RBIs this season, according to MaxPreps.com.

Oakland followed up Judge's selection with four more college picks. Included in that group was 6-foot-6 right-hander Sean Murphy, who played for Division III Keystone College in La Plume, Pa. Murphy went 6-3 with a 3.22 ERA in 2010, allowing 63 hits and 20 walks in 64 1/3 innings, while striking out 56.

Todd McInnis became a member of the A's organization in the 32nd round. McInnis went 6-5 with a 3.30 ERA for the University of Southern Mississippi, allowing 85 hits and 34 walks over 95 1/3 innings, while striking out 87.

The A's selected seven consecutive high school players in Rounds 40-46. Right-hander Andrew Smith (40th round) has committed to play at North Carolina, while 46th-round selection Tyler Skulina -- a 6-foot-5, 252-pound righty -- is signed to play at Virginia.

Oakland picked Zachary Johnson, a third baseman from Ohlone College, in the 48th round. Johnson attended nearby California High School in San Ramon.
