The Los Angeles Angels have signed right-handed reliever Tony Pena, the team has announced.
Pena has yet to pitch this season after undergoing Tommy John surgery last August. The 30-year-old was signed as an amateur free agent by the Arizona Diamondbacks in 2002 and made his major league debut with the club in 2006.
Over parts of four seasons with the Diamondbacks, Pena maintained an ERA of 4.08 with 6.5 SO/9 and 2.7 BB/9. Arizona then traded the right-hander to the Chicago White Sox in July of 2009 in exchange for first baseman Brandon Allen.
Pena logged three seasons with the White Sox before being released this off-season. He mostly struggled during his time in Chicago, posting an ERA of 4.93.
The Angels can use all the bullpen help they can get at this point. LA has late-inning options Scott Downs and Jordan Walden on the disabled list, and current closer Ernesto Frieri has surrendered nine earned runs over his last nine innings of work.
How large of a concern is the Angels bullpen?
