HOUSTON — A Major League Baseball official says umpire Bill Hohn will be addressed "in a very stern way" after a confrontation with Houston pitcher Roy Oswalt led to the ejection of the Astros' ace.

Bob Watson, the vice president in charge of discipline, rules and on-field operations for MLB, tells Houston television station KRIV that Oswalt will not be penalized further after Monday's incident.

Watson says Hohn will get a phone call from Mike Port, baseball's vice president in charge of umpires.

After missing the strike zone with a pitch against Washington's Josh Willingham, Oswalt looked toward the first base line and yelled something. Hohn took off his mask and yelled at Oswalt, who responded, "I ain't talking to you!" Hohn then ejected Oswalt.
