Alvarado was recalled from Triple-A Lehigh Valley on Sunday.
EDGE Analysis
Alvarado was demoted in late May after posting a 7.62 ERA and 15.4 percent walk rate to start the season, but four scoreless minor-league appearances in which he walked just a single batter was apparently all the Phillies needed to see to bring him back. Cristopher Sanchez was optioned in a corresponding move.
