Straily, 27, has been traded by the Houston Astros to the San Diego Padres in exchange for veteran catcher Erik Kratz.
Selected by Oakland in the 24th round of the 2009 MLB Draft, Straily spent his first two-and-a-half years in the majors with the A's. He went 13-11 with a 4.11 ERA with the A's before being part of a blockbuster deal with the Chicago Cubs in the middle of the 2014 season.
Straily was traded with Addison Russell and Billy McKinney to the Cubs for Jeff Samardzija and Jason Hammel. He was then a part of another large trade in the offseason, as he was shipped to Houston with Luis Valbuena for Dexter Fowler.

In four big-league seasons, Straily owns a 13-13 record with a 4.60 ERA.
Kratz, 35, has been a journeyman in baseball. Making his major league debut at 30 years old, Kratz has been a backup behind the dish for four teams in six years.
Playing in only 16 total games between the Kansas City Royals and Philadelphia Phillies last season, Kratz hit .192/.214/.269 in 26 at-bats.
Evan Drellich of the Houston Chronicle first reported Straily being traded to the Padres, while Dennis Lin of the San Diego Union-Tribune confirmed Kratz going to Houston.
