Karsay threw 30 fastballs at the Yankees minor league complex.
He did not pitch last season because of a shoulder injury that
required surgery in May.
"We're increasing the intensity each time," he said. "We'll

Karsay will increase his mound sessions to 35 pitches next week.

The right-hander went 6-4 with 12 saves and a 3.26 ERA in 78
games for the Yankees in 2002.

Yankees' facility in Florida. ... 2B Homer Bush, who retired last
spring when he was in spring training with San Diego, agreed to a
minor league contract with the Yankees. Bush, 31, hit .287 with 11
homers, 115 RBIs and 64 steals in 400 games over six major league
seasons with the Yankees, Toronto and Florida.
