Notes: Guillen's status unclear

X-rays, CAT scan negative for Tigers shortstop

DETROIT -- The Tigers had enough players lose their heads in Sunday's fracas against the Royals. They're hoping not to lose their shortstop for it.

Though Carlos Guillen seemed healthy amidst the on-field scrum after taking a pitch off his helmet in the sixth inning, he wasn't feeling as well after coming back into the clubhouse following his ejection. Head athletic trainer Kevin Rand said Guillen felt "a little dizziness" along with some nausea, signs of a possible concussion.

He was taken to Henry Ford Hospital for examination, where X-rays and a CAT scan were negative. He was expected to accompany the Tigers Sunday evening on their team flight to Chicago for the start of a three-game series against the White Sox on Monday. His playing status, however, wasn't known.

If he's out, it'll be another injury in what has proven to be a frustrating season for Guillen healthwise. Only in the last three weeks has Guillen been able to play on an everyday basis. Soreness in his right knee kept him in and out of the lineup for much of the first few months following ACL surgery last September. While compensating for the knee, he strained his left hamstring running the bases in June, putting him on the 15-day DL.

He came back off the DL June 26 and has been a fixture in the lineup ever since. Though he has yet to homer since being activated, his .339 average in July is his highest of any month this season.

Other injuries in Sunday's melee were minor, according to Rand. Manager Alan Trammell had a minor injury on his hand. Still, some players could end up missing time when Major League Baseball issues its disciplinary ruling on the issue. That will likely come in the next few days once the umpiring crew files its report and others watch the replay.

Heed the warning: Though the altercations were surprising enough for two clubs that hadn't fought since 2001, what might've been less expected was the second-inning warning to both benches from home plate umpire Marty Foster.

No Tigers thought Royals starter Ruelvys Hernandez was throwing at hitters in the first inning, when he hit two of the first three batters he faced. However, the frequency and the timing came into account once Detroit starter Mike Maroth hit David DeJesus in his right knee in the second inning.

Maroth had just erased a baserunner on a pickoff move. With a 3-2 count, he was a pitch away from ending the inning.

"It was a bad situation, I guess, with [Hernandez] hitting two guys in the first inning and all of a sudden two outs, nobody on," Maroth said. "I know it didn't look very good. I was surprised though, that he did issue it. The only reason he would give a warning is if he saw intent. I guess with two outs and nobody on, he thought about it."

Manager Alan Trammell came out to argue to no avail.

Catcher Vance Wilson was slightly surprised, but understood. "The umpire even told me the first couple from Hernandez, he thought sailed," Wilson said. "And obviously, Maroth's sailed. It wasn't intentional. [MLB puts] a lot of pressure on those umpires. It's kind of hard at that point to fault an umpire, because they're so hard on them about those things to control the situation. I was a little surprised only because it wasn't intentional. But when you look back, most umpires will do that."

Peacemakers: While Guillen, Hernandez and Kyle Farnsworth dominated the highlights from the game, and the sight of the dogpile will be a fixture on television for the next few days, the many Tigers and Royals who tried to act as peacemakers went relatively unnoticed.

Catcher John Buck initially held back Guillen from Hernandez until a familiar face stepped in. Former Tigers pitcher and current Royals hurler Jose Lima ended up escorting Guillen to first base and trying to calm him down. Dmitri Young and Juan Samuel were among those trying to hold back an angered Jeremy Bonderman, who was later pulled out of a fracas by hitting coach Kirk Gibson.

"I was trying to stop him from getting in trouble," Samuel said of Bonderman. "Guys just react to things like this."

About the only Tigers player strong enough to get in Kyle Farnsworth's way was bullpen coach Lance Parrish, who did so until Farnsworth escaped his grasp and ran after Jeremy Affeldt. Among those who helped break up that melee was Magglio Ordonez.

It's the veterans who knew better. "When [stuff] like that starts, unless you're cruising for a bruising, you don't talk [trash]," Young said. "You just try to make peace. You find someone that you know and sit there and giggle about it. Let everyone else do what they've got to do."

Someone asked Maroth why he didn't retaliate by hitting someone in the seventh inning. To Maroth, though, the best revenge would've been to win the game.

"It doesn't have to play out that way," Maroth said of retaliation. "I thought that by going out there and getting three quick outs and getting back in the dugout, I was hoping that would spark us and get the bats going. We weren't able to get it going with all the double plays we had."

Welcome to Triple-A: Hard-throwing Tigers prospect Joel Zumaya was roughed up in his debut at Triple-A Toledo Sunday, giving up six runs in 3 1/3 innings of an 11-3 loss to Buffalo at Fifth Third Field.

All but one of those runs came in a nine-run fourth inning. The 20-year-old fireballer walked four batters and hit two others while allowing four hits. He started in place of Wilfredo Ledezma, who's suffering from discomfort in his left elbow.
