LHP Danny Duffy will make his fourth major league start of the season after his return from Tommy John surgery that was performed on June 13, 2012, when he pitches the opener of a four-game series against the Seattle Mariners on Monday at Kauffman Stadium. He pitched 6 2/3 shutout innings last Wednesday in an 8-1 victory over the Twins at Target Field, allowing five hits and no walks while striking out seven. He has pitched 12 2/3 consecutive shutout innings including six scoreless innings in a 2-1 victory at Detroit on Aug. 16. This will be his first career appearance against the Mariners.
LF Alex Gordon was 1-for-5 with an RBI in Sunday's 5-0 win in the series finale against the Blue Jays and is on an eight-game hitting streak, batting .333 (12-for-36). He is batting .327 (16-for-49) with 11 runs scored since being returned to the leadoff spot in the batting order Aug. 22. His fifth career two-assist game against the Blue Jays in Saturday's 4-2 loss gave him an American League leading 14 outfield assists for the season.
C Brett Hayes has been added as a September call-up. It will be his second stint with the Royals. He was 3-for-11 with two doubles in a one-week stay with the Royals in early August when C Salvador Perez was on the seven-day concussion list. In 78 games at Triple-A Omaha, Hayes hit .233 with 15 doubles, 17 home runs and 44 RBIs.
RHP James Shields held the Blue Jays to three hits and a walk while striking out nine over seven innings in Sunday's 5-0 win. He has won four decisions in a row to improve to 10-8 and has recorded at least 10 victories in each of the past seven seasons. He is 12-6 in his career against the Blue Jays and in his past 25 innings at Rogers Centre has allowed one earned run for a 0.36 ERA. "I started throwing my changeup early, and this team knows me pretty well, obviously," Shields said. "They knew it was coming, and I made a little adjustment at the end of the game and started throwing fastballs later in counts, and tried to get through seven."
SS Alcides Escobar doubled in the ninth inning of Sunday's 5-0 win in the series finale against the Blue Jays to extend his hitting streak to six games. He is batting .286 (6-for-21) with two RBIs in that span. He has hit safely in nine of his past nine games. He entered Sunday sixth in the American League with 24 infield hits.
LHP Francisley Bueno has been added to the roster as a September call-up. He appeared in 36 games with Triple-A Omaha and was 3-3 with a 2.66 ERA and one save. He has one major league outing this season, earning the win in relief against Boston on Aug. 9.
1B Eric Hosmer had his second straight two-hit game in Saturday's 4-2 loss to the Blue Jays and finished August batting .323 (40-for-124) with 19 RBIs. His .388 on-base percentage for August is the highest he has had for any month in his career. He was 2-for-5 with three RBIs in Sunday's 5-0 win at Toronto and is on a five-game hitting streak, batting 8-for-20 (.400). He has reached base in 13 consecutive games, getting hits in 11 of them.
