Jesus Guzman is in the Padres' starting lineup on Friday and will be making his first career start at third base.

With Cody Ransom designated for assignment, it appears that manager Bud Black will give Guzman an opportunity to serve in a platoon role at third base until Chase Headley returns. Guzman played 46 games at third base at the Triple-A level in 2011.

Jesus Guzman went 2-for-4 and hit a three-run homer versus the Rockies on Saturday.

Guzman has done an excellent job as a platoon player, with a .306 average, four homers and 16 walks in 112 at-bats against southpaws this season. He doesn't have much defensive value, so he probably wouldn't be very valuable in an expanded role. He's an asset as is, though.

Jesus Guzman singled and launched a two-run homer in Monday's win over the Astros.

Guzman's two-out shot in the eighth inning briefly put the Pads ahead before they coughed up the lead in the bottom of the frame. They wound up winning in extras, with Carlos Quentin doubling in Chase Headley to score the winner. Guzman is batting just .241 with two dingers this season.
