A couple of interesting names are among the latest batch of players signed to minor-league contracts by the Phillies and invited to major-league spring training camp. Catcher Lou Marson, who was drafted by the Phillies in 2004 and traded to Cleveland in a package for Cliff Lee in 2009, has rejoined the organization on a minor-league deal. The team has also signed outfielder Tony Gwynn Jr. and invited him to big-league camp. Gwynn is the son of the Hall of Famer by the same name. He has spent parts of seven seasons in the majors and could be an attractive option for the Phillies because he hits left-handed. The Phils’ bench is deep in right-handed bats and short on left-handed hitters. The Phils also invited right-handed pitcher Sean O’Sullivan and outfielder Dave Sappelt to camp. All four players have major-league experience. Marson, 27, averaged 230 at-bats as a backup with the Indians from 2010 to 2012, but missed most of 2013 with neck and shoulder injuries. He was not tendered a contract by the Indians earlier this month and became a free agent. With Wil Neives having been signed to be Carlos Ruiz’s backup, Marson could provide some organizational catching depth to complement prospects Tommy Joseph and Cameron Rupp at the upper levels of the minor league system.
