Olbrychowski, a fifth-round Draft pick of the Yanks in 2007, spent the majority of last season at Class A Advanced Tampa before finishing the year at Double-A Trenton. Altogether, the 24-year-old registered a 3-2 record with a 3.90 ERA while working almost exclusively in relief.
Olbrychowski compiled a record of 16-17 with a 4.17 ERA in four Minor League seasons.
Last season, Maxwell split time between the Majors and Triple-A Syracuse. He batted .144 with three home runs for Washington, in addition to a .287 mark with six homers in 66 games at Syracuse. Now with the Yankees, Maxwell is hoping to build off his up-and-down season in 2010.
"It was definitely frustrating, not playing regularly at the big league level," Maxwell said Wednesday. "At Triple-A, I was playing every day, and then coming up, it was a different role as a fourth or fifth outfielder with the Nationals. It was an adjustment, to say the least, but I'll learn from it and I worked hard this offseason to get better."
Maxwell, who was designated for assignment Thursday by the Nats in an attempt to create roster space, owns a career batting average of .201 over 122 Major League games.
