Here is what we learned after this Cubs victory.
Rafael Dolis will be the closer for now: The closer job was supposed to be up for grabs until Carlos Marmol is able to figure out his pitching issues, but it appears Dale Sveum is comfortable with having Dolis as the closer. His second save of the year was less entertaining, as he casually slammed the door shut on the Dodgers offense. Dolis appeared to gain confidence after each pitch he threw, and if he continues to thrive as a closer, this could spell the end of Marmol's career in Chicago.
Paul Maholm is streaking: Maholm had another dominating performance as he limited the Dodgers offense to one run on three hits while striking out four. After his first two unmemorable starts to the season, Maholm has been lights out as he now has won three straight and given up only three runs in his last three outings.
Joe Mather needs to get his at-bats: Coming off the bench, Mather delivered a solo home run to add to the Cubs lead to make it 4-1. If it's starting or pinch-hitting, Mather has made most of his opportunities and he does provide offensive pop off the bench. The only question is with a crowded outfield, where does Mather fit in? Mather has to be hoping for an injury, a struggling player or a trade to guarantee him more playing time. That being the case, the Cubs need to find a way to have his bat in the lineup more often.
