Las Vegas oddsmakers have established the Rangers as minus-135 road favorites, while the total is 8.5, but facing upward pressure in the betting market.
Rangers starting pitcher Neftali Feliz (1-1, 3.81 ERA) is set to make his sixth appearance (fifth start), as he looks to bounce back from giving up a season-high four runs in five innings in a no-decision effort against the Toronto Blue Jays on the road.
The right-hander is 0-1 with a 5.00 ERA in three road starts, issuing 12 walks and striking out 13 batters in 18 frames. He finished with a 1.73 ERA in making 28 relief appearances on the road in 2011.
In seven career appearances versus the Orioles, Feliz has yet to receive a decision, allowing five runs and five hits over seven innings.
The Rangers are 35-16 in their last 51 games as a road favorite, while the "under" is 11-4-1 in that situation.
Orioles starting pitcher Jake Arrieta (2-2, 3.52 ERA) snapped a personal two-game losing streak in tallying a 5-0 road win over the New York Yankees last time out, tossing eight shutout innings and allowing just five hits.
The right-hander has produced an even 1-1 mark and 3.72 ERA in three home outings, giving up three home runs in 19.1 innings, but opponents are hitting just .164 against him.
Arrieta will be facing the Rangers for the fourth time in his career, going 1-2 with a 5.51 ERA, including a 13-1 setback at Camden Yards on April 9, 2011. The former fifth-round selection surrendered eight runs and six hits over 3.1 innings in that effort.
The Orioles are 2-6 in Arrieta's last eight starts as a home underdog, while the "under" is 8-3 in the last 11 meetings between these two teams in Baltimore.
Weather forecasts are suggesting isolated thunderstorms and game-time temperatures in the mid-70s, with 10-15 mph winds out of the south (out to left).
