Chavez, who turned 29 on Tuesday, has nine appearances in the Majors this season and 19 with Triple-A Las Vegas. He went 1-1 with an 8.44 ERA in his big league time, spread over three stints, and was 8-5 with a 3.98 ERA for Las Vegas. Most of his time at Triple-A this year was as a starter, while most of his action in the Majors came as a reliever.
It's likely that Chavez, who carried strong strikeout rates at both stops -- 86 in 95 innings with Las Vegas and 27 in 21 1/3 with Toronto -- will remain a reliever in Oakland's organization. For now, it appears he'll do so with Triple-A Sacramento, but in the future could offer the A's a long-relief option.
In parts of five Major League seasons, Chavez is 7-11 with a 5.74 ERA in 152 games. He's played with Pittsburgh (2008-09), Atlanta (2010), Kansas City (2011) and Toronto. Chavez has 143 strikeouts, 69 walks and has allowed 33 home runs in 174 innings.
Manager Bob Melvin has not yet acquainted himself with Chavez, but acknowledged the confidence he has in the decisions made by the front office, saying: "We evaluate pitching pretty well in this organization."
