The Giants have placed catcher Eric Haase on release waivers, relays Justice delos Santos of The San Jose Mercury News. Haase has spent the last three months on the big league roster. The Giants selected his contract when Susac landed on the injured list for the first time in mid-April. Susac again landed on the IL in late June, leading the Giants to select Drew Cavanaugh onto the MLB roster. Once the Giants were unable to line up a trade partner, a release was their only option.
