Since DL stint, when Duffy starts, Royals usually win

Kansas City Royals left-hander Danny Duffy's record since coming off the disabled list in late June is 4-2. But the Royals are 8-2 in those games -- and hoping to go to 9-2 after Duffy's start Thursday night in Boston.

Only two major league pitchers -- and no American Leaguers -- have enjoyed a higher winning percentage since the start of last month than Duffy.

While the Royals enter this series with the league's best record (73-46) and the Red Sox occupy the AL East basement (54-66), Boston has had Kansas City's number over the last two seasons, winning eight of 10 matchups. But that doesn't change the fact that the Red Sox, winners of the 2013 World Series, have endured one of the worst two-year stretches ever following a world championship season.

Royals designated hitter Kendrys Morales got some rest during the team's two interleague wins in Cincinnati, but he'll be back in the lineup this weekend. That's good news for the Royals, who welcome his .289 average, 13 homers and 83 RBIs. That RBI total ranks fifth in the league, but with two outs, no one in baseball has knocked in more runs than Morales.

Third baseman Mike Moustakas' numbers no longer stand out among some of his fellow Royals starters, but he gets his share of good at-bats when not producing hits.
