Boyer, 33, returned to the Majors for the first time since 2011 this past season and pitched relatively well out of the San Diego ’pen. The well-traveled veteran tallied a 3.57 ERA with 6.5 K/9, 1.8 BB/9 and a 42.5 percent ground-ball rate in 40 1/3 innings for manager Bud Black. Boyer has over five years of service time and projected to earn $1MM in arbitration (per MLBTR contributor Matt Swartz), and the Padres instead opted to use that roster spot to protect themselves heading into the Rule 5 Draft.
Asencio, who turned 25 last Friday, batted a combined .291/.330/.433 with 15 homers and eight steals in 572 plate appearances between Double-A and Triple-A. Baseball America ranked him 24th among Padres farmhands in each of the past two offseasons, more recently noting that he’s a bad ball hitter with an aggressive approach and a very strong arm in right field.
