Series preview: Cubs at White Sox

CHICAGO – Even though the Chicago White Sox continue to plod along with a stagnant on offense, they have found a way to close out victories in their last three games.

The last two of those games were at Wrigley Field, as the White Sox won Monday on Marcus Semien's RBI in the 12th inning. On Tuesday they got their go-ahead run came in the eighth inning on a home run from Gordon Beckham.

It hasn’t been pretty as the White Sox have batted just .191 (26-for-136) with three home runs as a team over their last four games. They have averaged three runs per game since Saturday, well under their 5.03 average since the start of the season.

Going back seven games, the White Sox are hitting just .207 (49-for-237) as a team with 15 doubles, four home runs and 21 runs scored. With runners in scoring position over that stretch, the White Sox are batting a paltry .145.

What has led the club has been the bullpen. White Sox relievers have a combined 1.53 ERA over the past 16 games, delivering 10 scoreless games in that stretch. It is the lowest bullpen ERA in the American League since April 20 and the second-lowest in the major leagues to Atlanta’s 1.49 mark.

While the arrival of Jake Petricka and Zach Putnam has triggered the shift, right-hander Ronald Belisario has also played a big role. Belisario has allowed just one unearned run with eight strikeouts and two holds over his last seven games (11 innings).

The results are a far cry from what was happening early in the season. Over the first 18 games, White Sox relievers had a 6.12 ERA. The change has been impressive.

Over the last 58 2/3 innings, the White Sox bullpen has given up 40 hits, 14 runs (10 earned) and 28 walks. Over the previous 57 1/3 innings those numbers were 60 hits, 41 runs (39 earned) and 41 walks.
