The Giants have overtaken the first baseman Trenton Brooks and left-handed Raymond Burgos unclaimed through waivers, tweets Shayna Rubin of the San Francisco Chronicle. Both were designated for assignment over the weekend and both have now been outrighted to Triple-A Sacramento.

Brooks, acquired in exchange last August, Sean Newcomb across the bay to Oakland, made his MLB debut this season as a 28-year-old rookie. He hit 3 for 25 (all singles), struck out six times and walked four.

That debut didn't exactly draw a lot of attention, but Brooks has been pounding Triple-A pitchers this season, throwing more walks than strikeouts. In 177 plate appearances, he has a batting average of .308/.426/.462 with a 17.5% walk rate and a 15.3% strikeout rate. He's hit four home runs and taken six bases. This is Brooks' fourth season at the Triple-A level, and he has a career batting average of .277/.377/.471 in 1,365 trips to the plate. That solid track record wasn't enough to convince another club to sign him, so he'll stay with the River Cats and give the Giants a backup option in case they need a left-handed hitter or some help at first base and/or in the outfield corners.

Burgos, 25, also recently made his major league debut with the Giants. It lasted just one inning, and Burgos allowed one run on three hits and one walk with a punchout in that brief debut appearance. The former Cleveland farmhand signed a minor league deal with San Francisco two offseasons ago and did so again earlier this year after pitching very briefly in Mexico. While he had lackluster results in Triple-A last year, Burgos has been outstanding this time in Sacramento. In 22 innings, Burgos has a 1.64 earned run average with a 27.4% strikeout rate and a ridiculously low 2.4% walk rate.

Like Brooks, Burgos will remain on the team in Sacramento as a reserve player. TaylorRogers And Eric Miller are currently the only healthy left-handers on the Giants' 40-man roster, so Burgos could quickly be back in the running for a major league position if something happens to one of the left-handers.
