Each week, CSNChicago.com goes down on the farm for a minor-league report from both the Cubs and White Sox system, presented by Service King.
The Cubs signed Joe Nathan to a major-league deal earlier this week, but if they're looking for some bullpen help, they don't need to look any further than Triple-A Iowa.
Spencer Patton was called up to the big leagues when Neil Ramirez went on the bereavement list and surrendered a hit to the only batter he faced. But in the minors, Patton hasn't allowed a run in 13 innings, picking up five saves.
Patton and Carl Edwards, Jr. have combined to strike out 42 batters in 27.1 innings.
Edwards (2.51 ERA, 1.256 WHIP in 14.1 innings for Triple-A Iowa) was also promoted to the big leagues for the Cubs' doubleheader last week, but did not appear in either game.
He had a 3.86 ERA and 1.286 WHIP in five games with the big club last season and figures to be one of the first names called up to Chicago if the Cubs need bullpen help down the line.
To boot, the Iowa Cubs also have a trio of other relievers turning heads with Felix Pena (1.86 ERA, 0.724 WHIP, 11.6 K/9 in 19.1 innings), Brandon Gomes (2.76 ERA in 16.1 IP) and Jean Machi (3.10 ERA in 20.1 IP).
Tim Anderson's hot streak continued over the past week.
The White Sox shortstop was named the International batter of the week on Monday.
In the last 10 games, Anderson is batting .426 with three homers, six RBIs, a triple and four stolen bases. His season average has also jumped from .231 to .300 during that span.
If he continues at this pace, he could reach the majors this season.
The White Sox acquired 26-year-old pitcher Anthony Ranaudo last week in exchange for reliever Matt Ball.
In Ranaudo's first start for the Charlotte Knights, he pitched four innings, allowing three hits, one run and striking out four. He earned a no decision.
