Alfonseca enjoyed a solid DWL regular season, going 1-0 with two saves and a 1.93 ERA in 9 1/3 innings. He also made seven relief appearances in the playoffs, allowing three runs over 7 1/3 frames.
Alfonseca was one of many players in the Phillies' organization who played winter ball. Here's how the others fared:
Arizona Fall League
RHP Joseph Bisenius -- Bisenius finished the AFL season with an unsightly 11.57 ERA for the Peoria Saguaros. However, he did not allow a run over his final three appearances, striking out six batters in 4 2/3 innings. The 24-year-old also appeared in 12 games for the Navegantes del Magallanes of the Venezuelan Winter League, where he went 0-1 with a 5.06 ERA.
LHP J.A. Happ -- A 24-year-old Illinois native, Happ was 1-0 with a 5.02 ERA in five appearances spanning 14 1/3 innings. Most of that action came at the Peoria Sports Complex, the Saguaros' home park.

RHP Chris Key -- A late addition to the Saguaros' roster, Key made six appearances and allowed eight runs over 10 2/3 innings. At 29, he was the oldest player in the AFL this season.
RHP Kyle Kendrick -- Kendrick earned his second victory in as many decisions after tossing 1 1/3 scoreless innings in the Saguaros' season finale. The 22-year-old yielded eight runs over 10 2/3 innings on the season, while opponents batted .362 against him.
