Rockies claimed LHP Sean Thompson off waivers from the Royals.
This keeps Thompson on a 40-man roster, but Thompson would have been better off if he remained with the Padres, who had him originally, or the Royals, who claimed him earlier this month then tried to slip him through waivers. Thompson doesn’t get an excessive number of grounders and his best pitch is a curve, which typically doesn’t work as well in Colorado. He’ll be optioned to Double- or Triple-A for now. He’s a long shot to succeed with the Rockies.
