Edinson Volquez has lost his spot in the Cincinnati Reds' rotation.
The right-hander was moved into the bullpen Saturday, giving him a chance to fix problems in his delivery. He retired only two batters in his last start, an 11-2 loss in San Francisco on Monday.
The Reds’ rotation is in flux heading into a pivotal week of their playoff push. Leading St. Louis by four games in the National League Central, Cincy finishes a weekend series against the Cubs, plays three at home against Milwaukee, then heads to St. Louis for their last three games of the regular season against the Cardinals.
Volquez had reconstructive elbow surgery last August and made it back ahead of schedule, returning to the mound last month. His arm is fine and his fastball is back to top speed, but his control has been inconsistent.
PITCHER UNDER INVESTIGATION
Major League Baseball is investigating New York Yankees pitcher Ivan Nova and former minor league teammate Wilkin De La Rosa for allegedly injecting each other with B-12 shots.
B-12 is not on baseball’s list of banned substances, but the New York Post, which first reported the story, said MLB is focused on the issue of whether the players injected each other and wants to make certain the shots were in fact B-12.
Police in Santo Domingo, Dominican Republic, have charged former major league pitcher Ambiorix Burgos with kidnapping and attempted murder after his ex-wife said she was forced to eat rat poison.
Burgos, who pitched for Kansas City (2005-06) and the New York Mets (2007), will stay in jail for three months while prosecutors prepare the case.
