PHILADELPHIA (CBS) – The Phillies have invited four additional players to Spring Training in Clearwater, the team announced Wednesday.

Outfielder Tony Gwynn Jr., catcher Lou Marson, right handed pitcher Sean O’Sullivan, and outfielder Dave Sappelt all got invites to major league Spring Training as non-roster invitees.

Gwynn played in 107 games with triple-A Albuquerque last season, batting .300 with a .393 on-base percentage, 12 doubles, five triples and 27 RBI in 333 at-bats.

In 2013, Marson appeared in just 12 combined games between the Cleveland Indians, triple-A Columbus and double-A Akron due to injury. The 27-year-old has compiled a .219 career batting average in parts of six seasons in the majors with the Philadelphia Phillies (2008-09) and Cleveland Indians (2009-13).

O’Sullivan, 26, spent the majority of last season with triple-A Tucson, going 8-5 with a 3.83 ERA in 20 starts. He also appeared in seven games with the San Diego Padres, including three starts, where he went 0-2 with a 3.96 ERA in 25.0 innings.

The 26-year-old Sappelt split the 2013 season between the Chicago Cubs and triple-A Iowa. He batted .240 in 31 games with Chicago and .252 in 90 games with Iowa while playing all three outfield positions for each team.
