Pitcher Dontrelle Willis announced his retirement last July, but he's had a change of heart and is going to give it another try with the Chicago Cubs. Willis has agreed to a minor-league contract with the Cubs, according to CBS Sports' Jon Heyman. The deal only includes an invitation to a minor-league camp, but he could get a shot with the Cubs if he pitches well. The left-handed Willis, who turns 31 on January 12, retired last summer after posting an 8.53 in four appearances with the Orioles' Triple-A affiliate. He has not pitched in the Major Leagues since 2011, when he went 1-6 with a 5.00 ERA for the Cincinnati Reds. Willis was National League Rookie of the Year in 2003 when he went 14-6 with a 3.30 ERA for the Marlins, and he was second in the CY Young voting in 2005, when he was 22-10 with a 2.63 ERA.
