Quick Hits: Castillo, Ryu, Dunn, Orioles

The Red Sox are “expected” to promote Rusney Castillo on Tuesday, Brian MacPherson of the Providence Journal tweets. This wouldn’t be shocking news, given that Ben Cherington has already said that Castillo is on track to be promoted this month and Triple-A Pawtucket’s season is about to come to an end, with the final game of the International League championship series taking place tonight. Castillo has played three games so far for Pawtucket. Here are more notes from around baseball.

• Dodgers starter Hyun-Jin Ryu is set to have his sore shoulder examined today, and Steve Dilbeck of the Los Angeles Times wonders what might happen if the results are unfavorable. Ryu missed several weeks with a shoulder inflammation earlier this season. Losing Ryu for the rest of the season would leave a Dodgers rotation (which has already lost Josh Beckett, Chad Billingsley and Paul Maholm) thin, and they’re in a tight race with the Giants for the NL West pennant. Of course, the cross-town Angels faced a similarly tough-looking situation when they lost Garrett Richards for the season, and they’ve been fine since then.
• If this is the last year for Athletics slugger Adam Dunn, it will be the end of an extremely unusual career, ESPN’s Jayson Stark writes, noting that more than half of Dunn’s career plate appearances have ended without him putting the ball in play. Players with similarly high strikeout, walk and homer totals usually have shorter careers, but Dunn has managed over 8,000 plate appearances (over 2,300 of which ended in strikeouts).
• Despite Chris Davis’ suspension, the Orioles aren’t inclined to promote first base prospect Christian Walker, CSNBaltimore.com’s Rich Dubroff writes. Walker has hit .288/.357/.489 in 599 plate appearances split between Double-A Bowie and Triple-A Norfolk this year, but he isn’t on the Orioles’ 40-man roster. “[S]ome guys don’t have to be protected this off-season, so unless I’m going to play them every day or mostly every day, or if I know they’re going to be on our team next year, then you’re really doing something that’s not very smart,” says Buck Showalter.
