Zagone (pronounced Zuh-go-nee), a 6-foot-4, 200-pound left-hander from Crystal Lakes, Ill., originally signed with the T-Bones last season on July 30. He went 1-4 with a 4.47 ERA in seven starts with Kansas City.
He struck out 16 and walked seven. Zagone played at the University of Missouri before the Baltimore Orioles selected him in the sixth round of the 2008 MLB Amateur Draft.
He spent five seasons in the Baltimore organization, reaching triple-A Norfolk in 2012. In six seasons, Zagone is 42-40 with one save, 506 strikeouts, 250 walks, and a 4.09 ERA.
“Zagone is a good left-handed pitcher who’ll compete for one of our starting spots,” said T-Bones manager John Massarelli.
Frias, a 6-foot-2, 190-pound switch-hitter from Los Alcanzzas, Dominican Republic, spent 2013 with Salem, a single-A affiliate for the Boston Red Sox, and Gateway of the independent Frontier League. In 67 games, he batted .265 with 61 hits and 33 RBIs.
San Francisco drafted Frias in the 30th round of the 2008 MLB Amateur Draft out of Tennessee Wesleyan College.
Frias, who reached triple-A Fresno in 2009 with the Giants and has played in the Chicago Cubs’ organization, also, is a career .240 hitter with 339 hits, 58 doubles, 11 triples, 17 home runs, 132 RBIs and 76 stolen bases in six professional seasons.
“I know him from the Frontier League, where a lot of baseball people thought he was the best shortstop in the league,” Massarelli said. “He’s athletic, can play short, second or third, and he has a lot of arm strength. Offensively, he has a lot of good instincts on the bases.”
