Torres, 28, spent the 2015 campaign with the Mets after coming over from the Padres in a Spring Training trade. He worked to a 3.15 ERA and struck out 35 batters in 34 1/3 innings of work, but he also averaged 6.8 walks per nine innings and was largely ineffective against left-handed batters, who hit .268/.406/.393 against Torres in 69 plate appearances. Despite a strong ERA, Torres was designated for assignment on Aug. 7 when the Mets acquired Eric O’Flaherty and subsequently outrighted to Triple-A Las Vegas. This offseason, he signed a minor league deal with the Braves, but he didn’t make the club after allowing four earned runs on six hits and five walks with seven strikeouts in eight spring innings.
The 2015 campaign marked the second straight season in which Torres had struggled considerably more against left-handed opponents than against righties, but he was outstanding against both in 2013 with the Rays. The Giants will hope that Torres can rediscover that form, though for the time being he’ll serve as a depth piece in the upper minors. Javier Lopez and Josh Osich are the club’s primary left-handed relievers. Those are the only two left-handed relievers on the club’s 40-man roster, though lefty Ty Blach is in the Triple-A rotation and could conceivably be an option as well.
