Jose Alvarez threw an eight-inning two-hitter to help the Jacksonville Suns finish off a five-game sweep of the Biscuits with a 4-0 win Tuesday.
Mark Thomas doubled with two outs in the third inning and Omar Luna singled to lead off the fifth for Montgomery.
Alvarez (5-6) walked none, hit Hak-Ju Lee with a pitch in the sixth and struck out five. Heavy rains ended the game in the middle of the eighth.
The 23-year-old left-hander recorded his second straight complete game. He gave up a run on five hits in eight innings in a 1-0 loss at Mobile last week. In his previous six professional seasons, Alvarez had just two complete games, both seven-inning shutouts in 2009 for short-season Lowell.
The Biscuits were swept in a five-game series for the fifth time in team history and second time this year.
