I'd just as soon have Swihart, JMart, Nunez or Lin (Holt when he's back) in LF than Castillo right now.
It's not like Rusney is doing anything special to earn a shot this year.
I'd like to see Swihart get a longer look than one game every 10 games. Let's find out what we have before trading or DFA'ing to bring up an equally unknown player that will kill our luxury tax this year and going forward. Say good bye to Kimbrel AND Pom, if we call up Castillo.
