The Brewers have informed Rule 5 choice Wei-Chung Wang that he will make the club's Opening Day roster, reports Tom Haudricourt of the Milwaukee Journal-Sentinel (via Twitter). The southpaw has impressed since being taken from the Pirates after his former club declined to protect him by adding him to its 40-man roster.

Of course, it remains to be seen whether Wang can stick on the active roster for the duration of the season. The 21-year-old Taiwanese hurler has never thrown above the Rookie ball level, though he was fairly dominant there while working almost entirely as a starter. Wang posted a 3.23 ERA in 41 1/3 innings, with 8.0 K/9 against 0.8 BB/9 and a 0.866 WHIP. Thus far in the spring, Wang has a 2.45 ERA in 11 innings, with six strikeouts and no free passes — quite an impressive showing for a pitcher of his experience level.
