A’s moves: Gallagher, Gio Gonzalez sent down, Javier Herrera released

The A’s roster shuffling continued Tuesday as they announced six player moves, including bringing up pitchers Edgar Gonzalez and Chris Schroder and releasing one-time prospect Javier Herrera.

Pitcher Sean Gallagher (1-2, 8.16 ERA), who gave up nine runs in two-plus innings in Monday’s 13-4 loss to Tampa Bay, was optioned to Triple-A Sacramento, as was left-hander Gio Gonzalez. In addition, the A’s transferred Eric Chavez to the 60-day disabled list.

Herrera was in the A’s minor league system for the past eight years and never fulfilled his promise. He was on the disabled list at Double-A Midland. The Herrera and Chavez moves enabled the A’s to make room on their 40-man roster for Edgar Gonzalez and Schroder.

Edgar Gonzalez was 3-2 with a 5.22 ERA in seven starts for Triple-A Sacramento. The ex-Diamondbacks pitcher was signed to a minor league contract by the A’s in February.

The 30-year-old Schroder, a one-time Washington National, was 2-1 with a 2.37 ERA in 14 games for Sacramento.

Gallagher was tagged for nine runs, seven earned, in last night’s 13-4 loss at Tampa Bay, as the 23-year-old righthander yielded five walks, three hits and a wild pitch before being lifted from the game in the third inning. It was his first start of the season with Oakland, but now leaves for Sacramento with a 1-2 record and 8.16 ERA in six games and 14.1 innings of work.
