Impact Krook surrendered two earned runs in one inning during his lone MLB appearance with Baltimore last season. He was much more effective during his time with Triple-A Norfolk, however, posting a 3.92 ERA and 1.41 WHIP across 43.2 frames. Now with the A's, the 30-year-old southpaw will most likely fill in as organizational depth at Triple-A Las Vegas.
