Buscher, who had earned a starting job in the last two weeks, suffered a deep bruise when he fouled a ball off his shin. The shin became infected and swelled up to a sizable bump. Twins manager Ron Gardenhire said Buscher will return to Minnesota.
"It's worse and it is really not looking good at all," Gardenhire said. "It's worse than [Tuesday], and we decided right now, let's get him in and let's get him checked out. We have talked about putting him in the hospital and putting him on IV and antibiotics, because this is definitely an infection and a bad one."
Buscher had batted .227 in eight games this season for the Twins before he went on the disabled list. The team is uncertain how much time Buscher will miss. Buscher will receive a MRI on Wednesday night. It is undetermined how serious the infection is.
"It is an infection, that's the way they way described it to me," Gardenhire said. "They didn't say staph infection yet. It's sore to the point where it is hurting all the time now."
Buscher, who had started seven games at third base in his first Major League stint, was only starting to be evaluated by the Twins.
"He was doing fine and we were working on some defensive stuff and he was coming along just fine, and that is the way the game goes," Gardenhire said. "It is tough to foul a ball off your leg and it turns into something. ... He is bummed out and like he said, it couldn't be worse timing. He is feeling the same thing. He would like to be out there and show what he could do."
Utilityman Tommy Watkins was recalled from Triple-A Rochester and should be in Kansas City for Thursday's day game. Watkins, batting .272 with 22 doubles, eight homers and 49 RBIs, will fill one of the two remaining spots on the Twins' 40-man roster.
Matt Tolbert and Jose Morales were considered options, but Watkins has impressed all season. Watkins, who carries a .303 average against left-handers this season, can play multiple positions, including second base, shortstop and third. The team will rotate several different players at third base.
"We are going to bring him up there and let him go at it, he played very well for us in the spring," Gardenhire said. "He has a good smile in his face and comes to play every day. You can play anywhere you put him, outfield, infield, so it will be fine to have him up there."
White nearing end of career? Rondell White could be playing his final year. In pain for most of the season, White is still unable to play the outfield.
"I ran a little bit yesterday and both hamstrings are kind of sore," he said. "I just go by day by day. I am trying to stay positive and hopefully get out there soon. It's been a frustrating year [with] my calf muscle, hamstring. I didn't realize the calf muscle takes two months to heal, but I guess it does."
He was supposed to start testing his legs on the grass at Kauffman Stadium, but the 100-degree heat and humidity has curtailed those efforts.
"It's not a good situation for us to run him out there and have him start sweating and start cramping up for a while," Gardenhire said. "It would be a worse thing for him. He ran around the bases OK [Tuesday] night and got through that."
White, a perpetually optimistic player, has played in just 10 games this season. In 14 seasons, White has a .284 career average and 750 RBIs.
"I don't know what I will be doing next year," White said. "I look in the mirror and if it's over, it's been a great ride. You always want to keep on playing, but sometimes your body says, 'Oh, hold up.' I played the game hard."
Nathan, Gardenhire discuss Bonds: Joe Nathan and Gardenhire each paid tribute to Barry Bonds' record-breaking 756th homer before Wednesday's game. Nathan, a former teammate of Bonds in San Francisco, called Bonds the best player he ever saw.
"I think that he is a special player," Nathan said. "He has all of the tools and when I was over there, he was a lot more healthy then. Just having a chance to watch him and play with him on a daily basis, it was something special."
"I think Barry Bonds is probably one of the best hitters you will ever see," Gardenhire added. "It's the quickest swing that I have ever seen and probably the most feared hitter in baseball for a pretty good while. I think that is proven by the numbers by how many times he has been walked and how many times someone has said, 'He is not going to beat us.'"
Nathan watched the post-homer ceremony on highlight shows and appreciated one of the most historic moments in baseball history.
"Obviously, the guy has been through a lot," Nathan said. "People have criticized him. He has been under a lot of scrutiny. People have assumed stuff about him, and for him to have that moment last night and for his family to be there ... and [it was a] class act for Hank Aaron to have a message for him.
"I think all in all, it was a good night for how Barry handled himself. Thanking his family, thanking the Nationals and thanking his teammates. It couldn't have gone any better for him," Nathan added.
