Wilhelmsen was optioned Monday, Jeff Wilson of Fort Worth Star-Telegram reports.

EDGE Analysis

Wilhelmsen gave up three earned runs in each of his last two outings so the Rangers felt that was enough to option him to the minors. The 32-year-old was not pitching well aside from his most recent late-inning disasters, as he has not had an ERA below 7.00 all season. Luke Jackson was promoted in a corresponding move as Wilhelmsen will look to regain his form with Triple-A Round Rock.
