Jacobs, 29, opened this season with the Mets, but he was designated for assignment in April and subsequently accepted a demotion to Triple-A Buffalo after clearing waivers. Jacobs has spent parts of six seasons in the Majors between stints with the Mets, Marlins and Royals.
Jacobs' best season in the big leagues came in 2008, when he belted 32 home runs and collected 93 RBIs for Florida. Over the past two seasons, though, he has hit .227 with a .297 on-base percentage. This year, Jacobs hit .208 with one homer in seven games for the Mets.
At Triple-A Las Vegas, Jacobs provides organizational depth at first base. On Thursday, the Blue Jays dealt their top first-base prospect Brett Wallace, who had been with Las Vegas, to the Astros in a one-for-one swap for outfield prospect Anthony Gose.
