"Chicago Cubs second baseman Mark DeRosa has left spring training in Arizona to undergo further tests on his heart at a Chicago hospital," reports the AP. "DeRosa met briefly with reporters at the Cubs spring training camp on Monday and said he may consider an unspecified surgical procedure to get his heart back into rhythm." He does hope to be back on the field within a week. The Cubs are certainly losing bargaining power in a possible Brian Roberts trade with this news. We wish DeRosa the best.
