First baseman Jose Abreu is having more fun playing baseball than ever before. He wants it to continue. For a long time. And with the White Sox. As he continues to perform at the same high, consistent level he has in each of his four seasons, and while he sets the bar high for individual work ethic by often being the first player at the park each day, Abreu is blossoming as a leader and enjoying himself even as a long, loss-filled season heads into the last two weeks. He’s all business but has lightened the mood by carrying a trash can through the dugout after home runs and laughing it up with teammates in other ways in the dugout, clubhouse and team bus. This from a player whose scowl after losses during his first three years was as consistently present as his RBI and multihit games. The difference now is growing stability and peace in Abreu’s life outside of baseball as well as a belief in where the Sox, in their rebuilding phase, are headed. “Definitely,’’ Abreu said Saturday. “That’s a huge factor. It also has to do with the organization. We’re on a better path. We already know what we’re doing. I’m just blessed to be here, living my dream and being around good people. “Even though our [60-88] record is like it is right now, the wave of new players here makes it fun. We’re just trying to enjoy it and have fun.’’ Abreu, 30, emphatically repeated before the game against the Tigers that he wants to finish his career on the South Side.
