FORT MYERS, Fla. -- The Pirates lost their final Grapefruit League game, falling to the Minnesota Twins, 4-3, Monday at Hammond Stadium in Fort Myers, Fla..
Pirates pitcher Anthony Claggett surrendered two runs in the ninth, including an infield single by Danny Lehmann to end it.
The club finished with an 11-20 record this spring and will play exhibition games today and Wednesday in Philadelphia against the Phillies before beginning the regular season Friday with the three-game series against the Chicago Cubs at Wrigley Field.
Monday, Jeff Karstens got the start, going 42/3 innings, giving up one unearned run on five hits as he struck out one and walked another.
His spring ERA was 1.54 in 112/3 innings.
The Pirates traded infielder Josh Fields on Monday to the Colorado Rockies for a player to be named later or cash.
Fields, signed as a minor league free agent in the offseason, was reassigned Friday to minor league camp.
He hit .172 (5 for 29) with 11 strikeouts in 21 spring-training games for the Pirates.
Nate Adcock, a pitching prospect Kansas City claimed from the Pirates in the Rule 5 draft in December, made the Royals' opening-day roster.
Adcock, 23, a right-hander, went 11-7 with a 3.38 ERA for high Class A Bradenton in 2010, with 113 strikeouts and 38 walks in 26 starts.
He pitched in relief for Kansas City this spring and will be in the bullpen.
Among the players the Pirates protected in the Rule 5 draft was journeyman reliever Wil Ledezma, who was released three weeks later.
