THIS SEASON: Doris Chen looks to back up her All-American debut as a freshman with another strong campaign as a sophomore. The 2012 Pac-12 individual champion who did not finish outside the top 30 in any event last year, appears ready to help lead USC on another national title run.
2011-2112: Chen earned 2012 NGCA All-American and All-Pac-12 first team honors, posting six top 11 finishes as a freshman last year, including a win at the 2012 Pac-12 Championship. Chen, who finished second on the team in stroke average at 72.85 with three rounds in the 60s, was ranked in the top 15 by season's end. She became USC's fifth conference medalist when she won the 2012 Pac-12 crown at 1-over 217 (77-72-68) for her first victory as a Trojan. She began the final round tied for 13th, but birdied five of the final seven holes to complete the comeback and the one-stroke win ... Chen followed that with a tie for eighth at the 2012 NCAA Central Regional at 5-over 221 (72-77-72), which marked her final top 11 finish of the year. She led USC with a tie for 14th at the NCAA Championships and completed the season never finishing outside the top 28 in any event ... After tying for 20th at the Stanford Intercollegiate in her only fall action, she tied for 10th at the Northrop Grumman Regional Challenge at 8-over 221 (72-71-78), finished seventh at the Allstate Sugar Bowl Intercollegiate at 1-over 217 (72-71-74), tied for ninth at the Battle at Rancho Bernardo at 3-over 147 (73-74), tied for 11th at the PING/ASU Invitational, tied for 28th at the Pacific Coast Intercollegiate before winning the Pac-12 title ...

Girls title and recorded four additional top-10 finishes in national junior golf, including a tie for fourth at the AJGA Junior at Innisbrook.
