Bush, home-plate ump exchange words

MINNEAPOLIS -- Denard Span scored the Twins' first of 15 runs on Friday and expected to see some high-fives waiting for him in the dugout. Instead, everybody was focused on the middle of the infield.

"I've never seen an umpire charge the mound," Span said.

Respected ump Ed Rapuano did not exactly channel Robin Ventura, one of the most famous mound-chargers, but he did advance toward Brewers starter Dave Bush after a close ball four forced home the first Twins run in a seven-run first inning that sent Bush to the showers before he recorded his second out.

Brewers first baseman Prince Fielder stepped between the pitcher and umpire, while Brewers manager Ken Macha stood near the top step of the dugout. Macha eventually joined the argument, but cooler heads prevailed, and Bush stayed in the game. He didn't fare any better after venting some frustration.

"It all happened pretty fast," Bush said. "I was pretty heated about it and so was he. I probably shouldn't have reacted quite that way. It was a big pitch, I thought I might have made it. It's still not really the best way to handle it, I guess. Sometimes emotions get the best of me out on the field. I try to keep it under wraps, but occasionally I can't quite help it."

His temper might have already been flaring before Rapuano's close call. Bush surrendered consecutive singles leading off the game, then walked Joe Mauer and fell into a 3-and-1 hole against Twins cleanup hitter Justin Morneau, who swung at a high pitch and popped out.

Up next was Michael Cuddyer. Bush again fell behind, this time 3-and-0, but worked the count full before a pitch that caught the bottom of the strike zone -- at least according to the Twins' television broadcast technology -- was called ball four. Cue the tempers.

"I think he caught everybody's attention," Span said of Rapuano. "I touched home, went in and scored and nobody gave me high-fives. Everybody was watching what was going on in the field. I was like, 'Hello, I Just scored here' but nobody was paying attention to me."

After Cuddyer's walk, Bush surrendered run-scoring hits to each of the next five hitters to make it 6-0. Span batted again and hit a grounder to Fielder, whose throw home was late. Seven-zip.

Did the argument with the umpire affect Bush's outing?

"I was already going bad by that point," he said. "I'm not sure it was better or worse after that."

The Twins won the opener of the three-game Interleague series, 15-3.
