Jerry Dipoto is remaking the Mariners so far by trading youth for age:

Seattle added to its bullpen Thursday, acquiring 38-year-old right-hander Joaquin Benoit from the San Diego Padres for two minor league prospects — right-handed pitcher Enyel De Los Santos and infielder Nelson Ward.

Dipoto saw Benoit pitch in September. He raved about his changeup and was impressed with his ability to still throw in the mid-90s by season’s end.

“A three-pitch, back-end guy with three out pitches at any given moment in time and that changeup just gives him a wipeout pitch to both sides,” the new Seattle GM said. “He’ll throw it to the right and the left. He’s been both durable and … a good fit for our ballpark.”

All de los Santos did in his age 19 season was strikeout lots of batters, walk few, and not give up home runs. Ward is 22, a bit old for A+ ball, but he’s in his second season in the majors. He seems to make a lot of plays per nine innings at shortstop, and has an okay OBP at that low level. The Mariners may get one or two years out of Benoit, but at that age a career can fall apart pretty quickly. de los Santos may end up looking like a pretty good pitcher, especially if he gets to play half his games in San Diego.
