Following the release of Luis Castillo during Spring Training the Mets gave the starting second base job to Brad Emaus whom they drafted from the Toronto Blue Jays during the rule 5 draft. But Emaus could not take advantage of the opportunity and lasted just 14 games with the Mets.
Emaus made his Major League debut on Opening Day and went 0 for 2 with a walk. During his next three starts he went for 4 for 11 but he then preceded to record just 2 hits over his next 23 at bats. Based on his slow start the Mets designated him for assignment on April 21. Since he was drafted in the Rule 5 draft he had to remain on the Mets 25-man roster for the entire season or else be offered back to the Blue Jays. The Blue Jays accepted him but then quickly traded him to the Colorado Rockies.
During his 14 games with the Mets Emaus batted .162 with one RBI.
Emaus did return to the Mets organization in 2012 but never made it out of the minors. He played 73 games for the Buffalo Bisons, the Mets triple A affiliate.
While with the Mets Emaus wore number 4.
