While en route from sfo-smf, air carrier X was on course nwbnd on the concord (VOR) 353 degree right approximately 30 DME. We were assigned 5000' and given a vector heading 020 degrees left of our present heading by travis approach on 132.1. This change put us on a heading of 335 degree. Travis issued this heading change due to numerous traffic in our vicinity. Travis approach had not however specifically pointed out any targets to us. We saw small transport Y at our 1 to 2 O'clock position approximately 200' to 300' above our altitude descending toward us. Small transport Y was in our blind spot until the last min. To avoid small transport Y the first officer (flying at the time) immediately turned left and descended approximately 500' to 700'. We then questioned the approach controller and he stated that there were too many targets to specifically point out or single out every one.

Title: ACR X HAD NMAC WITH SMT Y. SEE AND AVOID CONCEPT.
Narrative: WHILE ENRTE FROM SFO-SMF, ACR X WAS ON COURSE NWBND ON THE CONCORD (VOR) 353 DEG R APPROX 30 DME. WE WERE ASSIGNED 5000' AND GIVEN A VECTOR HDG 020 DEGS L OF OUR PRESENT HDG BY TRAVIS APCH ON 132.1. THIS CHANGE PUT US ON A HDG OF 335 DEG. TRAVIS ISSUED THIS HDG CHANGE DUE TO NUMEROUS TFC IN OUR VICINITY. TRAVIS APCH HAD NOT HOWEVER SPECIFICALLY POINTED OUT ANY TARGETS TO US. WE SAW SMT Y AT OUR 1 TO 2 O'CLOCK POS APPROX 200' TO 300' ABOVE OUR ALT DSNDING TOWARD US. SMT Y WAS IN OUR BLIND SPOT UNTIL THE LAST MIN. TO AVOID SMT Y THE F/O (FLYING AT THE TIME) IMMEDIATELY TURNED L AND DSNDED APPROX 500' TO 700'. WE THEN QUESTIONED THE APCH CTLR AND HE STATED THAT THERE WERE TOO MANY TARGETS TO SPECIFICALLY POINT OUT OR SINGLE OUT EVERY ONE.
