The aftershocks from Greg Holland’s momentary lapses in Friday’s ninth inning were still apparent the next afternoon. Manager Ned Yost blamed himself for overusing his closer. Holland insisted he would continue to answer the call, even as he dealt with fatigue. His weariness manifested against the Twins in a lack of command. Pitching coach Dave Eiland remarked to Yost that Holland lacked his usual arm speed. He appeared to be losing his balance on the mound and drifting early in his delivery, Eiland explained, which leads to pitches up in the zone, like the one Minnesota Oswaldo Arcia smoked for an RBI double. “A lot of times, when you drift, it’s because of fatigue,” Eiland said the next afternoon at Target Field. “Which goes along with the workload. But this time of year, everybody’s a bit fatigued. You have to fight through it.” Yost hoped to use neither Holland nor set-up man Wade Davis for Saturday’s game, but he is reluctant to specifically set aside days to rest Holland and use Davis as his closer. He does not want to burn out Davis, either. And he cannot take games off as the club attempts to win their first division title since 1985. It is worth remembering that the Royals won on Friday. Holland has given up three runs in eight appearances this August. He has appeared vulnerable at times during the end of the last homestand, allowing San Francisco to load the bases in one appearances, and letting two batters on when facing Oakland in another. These are the standards Holland has set for himself. He is a two-time All-Star. He may be the American League’s best closer. And his ability is critical as the Royals push for the playoffs. Holland (1.86 ERA, 37 saves) has appeared in 50 games thus far in 2014. The workload has become routine for him. He pitched in his 50th of 2013 on Aug. 16 last year, working back-to-back in a doubleheader. In 2012, he appeared in his 50th game on Aug. 19.
