In three innings against the Milwaukee Brewers, he allowed one run on one hit with five walks.
Penny said, no worries.
"I was just working on my splitter," he said. "When I couldn't get a strike, I threw another, then another. I just kept throwing it."
Nonetheless, Penny finished the Spring with a 0.95 ERA. Manager Joe Torre said Penny asked to pitch a fourth inning, but management needed to see several relievers throw and the results were mixed.
Rudy Seanez, whose middle-relief job seems to be on the line, was charged with two runs in two-thirds of an inning, although he was undermined when center fielder Jason Repko lost a line drive in the sun. If Seanez is on the Opening Day roster, he receives a $150,000 bonus. His spring ERA currently sits at 7.71.
Seanez could be replaced by rookie Ramon Troncoso, who retired the first two batters he faced, but walked the next one on four pitches. That set up left-hander Mike Myers, who struck out the only batter he faced. If Myers is not guaranteed a roster spot by Thursday, he can escape from his contract and become a free agent.
Scott Proctor, having ironed out a mechanical flaw, retired the only four batters he faced. Proctor and Myers pitched for Torre in New York.
"Proctor was very good," said Torre. "He had better command of the strike zone."
