Bergen fired a scoreless inning while striking out one in Sunday's 4-0 loss to the Rockies. Bergen showed enough in the minors last year (0.50 ERA and 4.8 K:BB ratio over 35.2 innings at Double-A New Hampshire) and during spring training this season to break camp with the Giants. The 25-year-old hasn't disappointed early on, allowing just one run on two hits with six strikeouts over 5.1 innings. San Francisco has a pair of talented lefties (Will Smith and Tony Watson) anchoring things at the end of the bullpen, but Bergen could see himself getting more late-inning opportunities if and when the aforementioned southpaws get moved at the trade deadline.
Manager Bruce Bochy said Tuesday that Bergen would be included on the Giants' Opening Day roster, John Shea of the San Francisco Chronicle reports. The Giants scooped up Bergen in the Rule 5 draft over the winter after a season in which he compiled a 0.50 ERA, 0.99 WHIP and 43:9 K:BB in 35.2 innings of relief at Double-A New Hampshire in the Blue Jays organization. The lefty continued to excel this spring, surrendering two runs and striking out 13 over 10.2 innings while holding opposing hitters to a .128 average. He'll likely be slated for usage in lower-leverage scenarios initially but could move up the Giants' relief depth chart quickly.
