AL West Notes: Castillo, Jackson, Parker, Gonzalez, Pujols

Though his role with the Cubs had diminished, Welington Castillo was still “shocked” to learn he’d been traded to the Mariners, he tells Ryan Divish of the Seattle Times: “I wasn’t expecting it. Now I’m here. It was a long day yesterday. Now I’m here and ready to go. I’m really excited to be here.” Castillo discusses the sometimes overlooked difficulty of being traded for a catcher, as he’s already been informed that he’ll be behind the dish for Thursday’s matinee, leaving him scarce time to get to know starter J.A. Happ, whom he’ll catch for the first time in his career. “I’m going to go and sit and watch video with him and go over the lineup, ask him, ‘what do you want to do, what do you like to do? What’s your first pitch? What’s your last pitch? What’s the pitch you throw behind in the count for a strike?’” Castillo is excited for the opportunity to play more, as even though he won’t be Seattle’s everyday option at catcher — that honor will still go to Mike Zunino — he should now pick up a couple of starts per week. With the Cubs, Castillo had just 47 plate appearances on the season.

• After speaking with Mariners director of minor league player development Chris Gwynn, Divish also reports that top prospect and 2014 first-rounder Alex Jackson has been shut down with a shoulder issue. According to Gwynn, Jackson hurt his left shoulder in Spring Training while diving for a ball, and the injury has likely hampered his swing this season. That would explain how Jackson, who slashed .280/.344/.476 in his pro debut with the club’s Rookie-level affiliate in 2014, saw his production plummet to .157/.240/.213 with Class-A Clinton in 2015. Jackson will head to extended Spring Training for the time being as he works to rehab the injury.
• Athletics righty Jarrod Parker underwent successful surgery to repair the fractured medial epicondyle in his right elbow, reports MLB.com’s Jane Lee. The club briefly thought that Parker might need a third Tommy John surgery after he initially sustained the injury, making this operation something of a relief, despite the its generally unfortunate nature. There’s still no timetable on his recovery, however.
• The Rangers’ decision to designate Carlos Peguero earlier today opened a spot on the 25-man roster and was likely influenced by the impending return of Josh Hamilton (who will pick up most of Peguero’s at-bats in the corner outfield), but Jeff Wilson of the Fort Worth Star-Telegram tweets another wrinkle to the move. The open spot on the 40-man roster won’t be filled immediately — Klein was already on the 40-man, as is Hamilton — which could allow the Rangers to give former first-round pick and consensus Top 100 prospect Alex “Chi Chi” Gonzalez a look in the rotation if they wish. Gonzalez hasn’t dazzled in his first taste of Triple-A pitching, but the 23-year-old does have a lifetime 3.14 ERA with 7.0 K/9 and 3.0 BB/9 in the minors.
• Albert Pujols left the game tonight after being hit by a pitch on the hand, but Angels GM Jerry Dipoto told reporters, including Mike DiGiovanna of the L.A. Times (Twitter link) that there are no fractures. Pujols will be day-to-day with a bruise but shouldn’t miss any significant amount of time.
