Exposito, who is on the 40-man roster, batted .381 with a .481 on-base percentage in 14 spring games. But the 26-year-old had struggled defensively, making two errors, including a catcher’s interference that allowed the winning run to score when he scooped up a live ball with his catcher’s mask.
Exposito, who batted .056 in nine games with the Orioles last year, will compete for the starting job at Norfolk.
Lefty Daniel Schlereth posted a 12.00 ERA in six games. He allowed 10 hits, three walks and eight earned runs in six innings.
Right-hander Adam Russell was 1-0 with a 7.71 ERA in eight appearances. He allowed 10 hits, four walks and six runs in seven innings.
Schlereth and Russell likely will compete for bullpen spots at Norfolk. They have 45 players left in camp.
