After briefly retiring from baseball in 2003, 22-year-old righthander Charles Haeger was added to the White Sox 40-man roster. Not bad for someone who went 1-6, 5.18 in 57 innings at Rookie-level Bristol in 2004.
Haeger's season with the La Guaira Sharks in the Venezuelan League got off to a hot start, earning him player of the week honors in the third week of the season. That week, Haeger pitched 16 innings, giving up two runs on 14 hits. He walked four and struck out seven, going 2-0, 1.13 over that span.

Besides renewed mental strength, Haeger has been working on a slurvy breaking ball to add to his arsenal. "I'm just starting to play with it," he said. According to Espinosa, the inspiration came from manager Cora, who faced Tim Wakefield and pointed out that the Red Sox knuckleballer varied his pitches by throwing the occasional breaking ball and a fastball.
