How to bet Sunday night's Giants-Pirates matchup

ESPN's Sunday Night Baseball focuses on the National League wild-card race, as the defending World Series champion San Francisco Giants close out a four-game series at Pittsburgh.

Entering Sunday's action, the Pirates are the NL's top wild-card team -- three games ahead of the Chicago Cubs, with the Giants another five games back. San Francisco, which is actually closer to a playoff spot in the NL West, as it only trails the Los Angeles Dodgers by 1.5 games, has failed to make up ground so far this weekend, as the Pirates have won two of three games in this series.

Francisco Liriano (8-6, 3.35 ERA, 1.14 WHIP) takes the mound for the Pirates, with Ryan Vogelsong (9-8, 3.93, 1.35 WHIP) going for the Giants.

Our ESPN Chalk baseball handicappers took a step backward last week, but Joe Peta is still 10-7 on Sunday Night Baseball games with a net profit of 3.35 units (laying the price to win 1 unit when taking the favorite and laying 1 unit when taking the underdog), Dave Tuley is 7-4 for a net profit of 2.65 units, and Andrew Lange is 5-4 with plus-0.97 units, so we're all still showing an overall profit. This Sunday night, Peta and Lange land on opposite sides, while Tuley looks at the over/under.
