Free-agent pitcher Kenny Rogers abruptly fired his agent Scott Boras and is now representing himself in present contract negotiations, MLB.com reports. Rogers, who told MLB.com Thursday that he still hoped to re-sign with the Detroit Tigers, informed Major League teams Friday afternoon that he formally severed his business relationship with Boras, the league's Internet arm reported. The dismissal by Rogers, who had been talking to the Tigers but also exploring other options, was confirmed for ESPN.com by team sources. The 43-year-old lefthander was 3-4 with a 4.43 ERA in an injury-shortened season for the Tigers after helping them reach the 2006 World Series.
