Orioles notes (oddsmakers, Jurrjens, Gamboa, Robinson)

In other Orioles news, right-hander Jair Jurrjens was officially optioned to Triple-A Norfolk today. He was designated off the 25-man roster on Sunday to make room for Brian Roberts, but remained on the 40-man roster.

It's a complicated procedural thing, but basically Jurrjens needed to clear option waivers -- which everyone does -- to officially be optioned to Norfolk. He had 72 hours from Sunday to join the Tides and he said he would take the time with his family and then return to Norfolk.

Jurrjens has a 4.91 ERA in two appearances with the Orioles including a scoreless 2 1/3 inning stint Saturday versus the Yankees.

Double-A Bowie Baysox knuckleballer Eddie Gamboa has been named Eastern League Pitcher of the Week for the week ending Sunday, when he threw a seven-inning no-hitter. In his past two starts, Gamboa (4-5, 3.48 ERA) has allowed one hit over 14 1/3 innings and has pitched seven or more shutout innings in three of his past four starts. He is the first Baysox pitcher to win the award since Jake Pettit in Aug. 2012.

One other note: outfielder Trayvon Robinson, acquired in the offseason deal with Seattle for Robert Andino, has been demoted from Triple-A Norfolk to Double-A Bowie. The 25-year-old was hitting .220 with five homers and nine steals in 52 games with the Tides.
