Taschner figures to fill the spot vacated by J.C. Romero's 50 game suspension for violating the league's substance abuse program, although his stats against lefties haven't been overwhelming.
Last season, left-handers hit Taschner - who turns 31 in April - to the tune of a .279 average and in his career, lefties have averaged .288 against him while right-handers have hit just .247 off of Taschner.
Overall, Taschner went 3-2, 4.88 in 67 games with the Giants last season. His career mark stands at 8-4 with a career 5.01 ERA during all or part of four seasons with the Giants.
Paulino didn't last long in Philadelphia, spending just over three months in the organization after they acquired him from Pittsburgh for minor league catcher Jason Jaramillo. Jaramillo is hitting just .143 (4-for-28) this spring for the Pirates.
Paulino hit just .194 (6-for-31) in camp with the Phillies this spring. His exit would appear to mean that Chris Coste has held onto his back-up catcher's job with the Phillies. The other option would be for catching prospect Lou Marson to stick with the club, but that's unlikely since the Phillies want him to play everyday.
Romero's suspension will keep him off the Phillies roster until June 1st.
