The River Cats blew a four-run lead Sunday night and lost 7-6 in 12 innings to the host El Paso Chihuahuas.
Sacramento led 5-1 after five innings. But El Paso rallied, scoring once in the ninth to tie it 6-6.
The Chihuahuas won in the 12th when River Cats reliever Curtis Partch issued four walks. The last came to Rico Noel with the bases loaded and two outs.
Kevin Frandsen went 3 for 6 with two RBIs, and Juan Perez added a two-run double for Sacramento.
River Cats starter Ty Blach went six innings, allowing two runs. But five Sacramento relievers combined to allow nine hits and five runs.
The Chihuahuas tied it in the ninth thanks to Sacramento gaffes. Noel, a pinch runner, went to second base on Erik Cordier’s wild pitch, stole third and scored on catcher Trevor Brown’s throwing error on the play.
On Monday at 7:05 p.m., the River Cats return to Raley Field to face the Fresno Grizzlies in the opener of a seven-game homestand. Giants right-hander Matt Cain, on a rehabilitation assignment for a strained right flexor tendon, is scheduled to start for Sacramento.
Cain made his first rehab start Tuesday with Double-A Richmond, allowing two runs in 32/3 innings against Portland.
