Rettenmaier Gains, Even as He Loses : Tennis: Camarillo boy, 11, makes presence felt but bows out of Easter Bowl in quarterfinals.

Four months ago, Travis Rettenmaier had no thoughts of the Easter Bowl, the United States’ largest national invitational tennis tournament for juniors. And Easter Bowl officials had no thoughts of him.

But Rettenmaier, 11, came from virtually nowhere to became the youngest boy to play in the 1995 Easter Bowl, which has attracted 384 competitors to a new venue--the Rivera Resort and Racquet Club.

Rettenmaier, of Camarillo, Wednesday lost to Cody Jackson of Westminster, 6-4, 6-4, in the quarterfinals of the 14-and-under division. After winning the first three days, his run at an improbable championship was halted. But Rettenmaier continued to turn heads.

“Everybody was all over him today--people, the media . . .,” said Karen Rettenmaier, Travis’ mother. “He has been made the focal point of this tournament, which is incredible.”

Rettenmaier, who jumped from the 12-under division to 14s in January and has since been one of the best in Southern California, defeated Jonathan O’Steen of Bradenton, Fla., and Phillip Metz of Mentor, Ore., by scores of 6-2, 6-2, in the first two rounds. In the Tuesday’s third round, Rettenmaier beat Michael Calkins of Portland, Ore., 7-5, 2-6, 6-4.

“He played his best tennis up until today,” Karen Rettenmaier said. “I think Travis earned his spot here.”

In other matches, Erin Boisclair of Agoura Hills, who won the girls’ 16s singles division last year, advanced to the quarterfinals of the 18s with a 6-3, 4-6, 6-3 victory over second-seeded Jennifer Hall of Oklahoma City.

Eighth-seeded Bob Bryan of Camarillo defeated Joseph Gilbert of Fullerton, 7-6 (10-8), 6-4, in boys’ 18s. His twin, No. 7 Bob Bryan, lost to Ty Braswell of Umatilla, Fla., 6-2, 6-2.
