Holman was optioned to Triple-A Las Vegas on Sunday, MLB.com reports.

EDGE Analysis

Holman was seen as having a chance to win a major-league bullpen role and was having a good spring with a 3.00 ERA and 3:0 K:BB in six innings, so this is a mild surprise. He showed promise last year as a rookie in a short stint with a 4.02 ERA and a 21.9 percent strikeout rate. He'll likely be one of the first callups if there's opening in the bullpen.
