Before the fourth and final game of the Padres current road series with the Brewers, the team announced a pair of roster moves. Relief pitcher Leonel Campos, who was up for just one game for the second time this season, was sent back to AAA El Paso; to take his place on the active roster they called up Tayron Guerrero. The 25-year-old native of Boca Chica, Casanare, Colombia is in his seventh year with the organization, and his second with time at the AAA level.
Guerrero stands 6'8" tall and touches the high-90s with his fastball. He has averaged exactly one strikeout per inning in his minor league career thus far, but has bumped that rate up to 1.1 in each of his tastes of AAA. He also walks a lot of batters, a longstanding issue that has not abated with time. In his seven seasons moving up the ladder he has walked 6.1 batters per nine innings; in his small sample sizes in AAA - 13.2 innings over 11 games last season, and 10 innings in another 11 games this year - his rates have been 7.2 and 6.3, respectively. In addition to limiting contact, Guerrero also has a history of limiting useful contact, allowing 7.5 hits per nine innings overall, with those numbers shrinking to 5.3 and 6.3 in his aforementioned AAA stints.
His prospect luster has faded due to his continued persistence on allowing hitters to jog to first base, but he could still prove to be a rather useful piece out of the 'pen. It's likely we'll see him make his major league debut today, as last night's 82-inning affair used every available arm.
