Mariners acquired RHP Sam Gaviglio from the Cardinals in exchange for INF/OF Ty Kelly.
Gaviglio, a former fifth-round pick, held a 4.28 ERA with 126 strikeouts over 136 2/3 innings at Double-A this season. The 24-year-old could start next season at Triple-A.
Cardinals acquired INF/OF Ty Kelly from the Mariners in exchange for RHP Sam Gaviglio.
Kelly has been added to the Cards' 40-man roster and could have a shot to crack the Opening Day roster in a bench role. The 26-year-old is a career .282/.387/.386 hitter in the minors, switch-hits and can play all over the field.
Padres designated OF Yeison Asencio for assignment.
Asencio hit .291/.330/.433 with 15 homers over 138 games between Double- and Triple-A this season. He just turned 25, so it's possible he'll draw interest on waivers.
Padres designated RHP Blaine Boyer for assignment.
Boyer pitched pretty decently for San Diego in 2014, holding a 3.57 ERA over 32 relief appearances. He was arbitration-eligible, though, and the Padres decided they had a better use for the 40-man roster spot.
Padres purchased the contract of OF Alex Dickerson from Double-A San Antonio.
Dickerson missed most of the season following heel surgery, but he played well when healthy, batting .321/.367/.496 with three homers over 34 Double-A contests. He's now protected from the Rule 5 Draft.
