Joel Pineiro is not exactly in the prime of his career and is coming off a rough season with the Anaheim Angels. For that reason, the 33-year old veteran likely realized that getting a minor league deal with the Phillies might be his best shot at squeezing out more time as a major leaguer.
While Pineiro is a long-shot at best to make the rotation out of camp, you never know when an injury or some double-headers may pop up requiring the Phillies to look outside the rotation for help.
Pineiro spent the past two seasons pitching for the Angels and is coming off one of his worst season as a major league pitcher, having gone 7-7, 5.13 in 27 games with Anaheim. Most of Pineiro's career has been spent in the American League, but he did spend two-and-a-half seasons with the St. Louis Cardinals, going 28-23 with a 4.14 ERA during his time in the National League.
It's also possible that Pineiro could provide left-handed help out of the bullpen should the Phillies need to add relief help.
Pineiro started his major league career in 2000 with the Seattle Mariners and has also pitched for the Boston Red Sox in addition to his stints with Anaheim and St. Louis.
