"Every day, it's been something for a while now," he said. "I hope this is the last of it."
Before Sunday's game against the Cubs, the Reds sent a player to the disabled list for the fourth time this month and held another out of the lineup with a minor injury. Relief pitcher Jared Burton was placed on the disabled list with an undiagnosed ailment, while catcher Ryan Hanigan, the replacement for the injured Ramon Hernandez, sat out for the second consecutive game with a sore neck.
In one piece of good news for the Reds, Baker said left fielder Laynce Nix was available for Sunday's game after not playing the two previous days due to his own sore neck. However, Jonny Gomes got the start in left.
Burton's injury is the most concerning for the Reds, mostly because they are not sure what it is. The big right-hander was recalled from Triple-A Louisville on July 20 and in two appearances since, has given up five runs in 2 1/3 innings.
"We figured something was wrong, because he wasn't throwing the same," Baker said.
Burton normally keeps himself in good shape but said his velocity is down and his body feels weak. He will get blood work done Monday morning.
"I just need some answers to know what I can do to alleviate the situation," Burton said.
Josh Roenicke was recalled from Louisville to take Burton's place on the roster and was available for Sunday's game. Roenicke, a 26-year-old righty, compiled a 2.92 ERA in 10 relief appearances for the Reds earlier this season before he was sent back to Triple-A on July 16.
Craig Tatum, who was called up to take Hernandez's roster spot, got the start in place of Hanigan for the second straight day. Hanigan's neck began to spasm when he took batting practice Saturday after he had slept on it awkwardly the night before. He expects to return to the lineup soon.
"It's definitely improving," Hanigan said. "The pain's still there, but the range of motion is better."
