The Phillies optioned Rangel to Triple-A Lehigh Valley on Saturday.
Rangel was never a likely bet to break camp with the big club, and his struggles during spring training (eight earned runs allowed with a 4:4 K:BB over 7.2 innings) solidified his fate. Rangel should begin the season as a rotation piece for Lehigh Valley, where he had a 4.65 ERA and 1.31 WHIP in 24 starts last year.
