LOS ANGELES (AP) — The Kansas City Chiefs are trading Pro Bowl cornerback Marcus Peters to the Los Angeles Rams for what is expected to be a package of draft picks, according to published reports. ESPN.com first reported the trade, which will not become official until the start of the new league year on March 14.

SURPRISE, Ariz. (AP) — The Royals like what they see so far out of Burch Smith. Kansas City got the hard-throwing, 27-year-old right-hander in the Rule 5 draft from the Rays. He’ll have to stay on the roster all season or be offered back to Tampa Bay. Smith was drafted out of Oklahoma in 2011 and made it to the majors two years later, but has missed most of the past three seasons with injuries. He could start for Kansas City or serve as a power arm out of the bullpen.

JUPITER, Fla. (AP) — Cardinals manager Mike Matheny isn’t sure when first baseman Matt Carpenter will make his Grapefruit League debut. Carpenter is battling back tightness. For the time being, he is in the hands of the Cardinals’ medical staff, who will determine when Carpenter can return to the field. Carpenter also missed much of last spring with back and oblique soreness.
