Two injured by explosion at Jacobs Field

CLEVELAND - As the explosion echoed through Jacobs Field, players stopped in their tracks, a few ducked for cover and Philadelphia manager Larry Bowa cringed. <br> <br> ``I didn&#39;t know what is was,&#39;&#39; Bowa said. ``These days you think the worst.&#39;&#39; <br> <br> The explosive device was thrown from the upper deck during the Indians&#39; game against the Phillies on Tuesday night, burning two people - one an Indians employee. <br> <br> ``It looks like either it was homemade or something that is restricted to a pyrotechnics professional,&#39;&#39; Cleveland Fire Chief Kevin Gerrity said. <br> <br> The three men suspected of throwing it - Donald Kreiger, 22; Clifton Oliver, 22; and Andrew Mendez, 20, all of Elyria - remained in jail Wednesday night. They had not been charged but were being held on suspicion of felonious assault and aggravated arson. <br> <br> Fire Lt. Clayton Cunningham said investigators want to be sure what was set off before deciding what to do about charges. <br> <br> Witnesses said the device was about 8 inches long. It shattered the plastic name tag on usher Brian Burke&#39;s chest and burned Judith Knight&#39;s legs, police said. <br> <br> Knight, 43, of Strongsville, was leaving the game when the device exploded a few inches from her. She was treated at MetroHealth Medical Center and released. <br> <br> ``She was pretty shaken up,&#39;&#39; Indians spokesman Bob DiBiasio said. <br> <br> Burke&#39;s chest was burned. He was treated at Jacobs Field. <br> <br> The blast in a lower-level smoking area was heard throughout the ballpark in the top of the ninth inning of the Indians&#39; 5-1 victory. <br> <br> ``I looked around for smoke,&#39;&#39; Indians designated hitter Ellis Burks said. ``And all the fans got really quiet.&#39;&#39; <br> <br> Burks said he doesn&#39;t feel unsafe on the field, but worries about how fans could be susceptible in today&#39;s uncertain times. <br> <br> ``With the stuff that&#39;s going on, you come out to a ballgame and you are open prey for a terrorist or anybody,&#39;&#39; Burks said. ``All it takes is for somebody to do something stupid.&#39;&#39; <br> <br> A few of the players on the field ducked their heads, and both dugouts emptied when the explosion went off at 9:23 p.m. <br> <br> ``It was loud,&#39;&#39; Indians manager Charlie Manuel said. ``It sounded like two trucks running together.&#39;&#39;
