Mariners left-hander Jason Vargas (10-7, 3.91 ERA) is slated to take the hill against Royals righty Luis Mendoza (4-6, 4.31 ERA). Which way should us baseball bettors look with our MLB picks in tonight's late night showdown?

Joe Freda’s 2012 MLB Record: 41-44-2 (-4.13 ROI)

The Seattle Mariners went 3-1 earlier this month in a four-game road set with the Kansas City Royals, outscoring Ned Yost’s club by a combined margin of 31-19. Thursday’s MLB schedule has the foes shifting to Seattle’s Safeco Field, where lower-octane duels have had the UNDER cash at 6-1 in the Mariners’ last seven home dates.

Sports books opened Vargas as a 115 favorite, while first setting the ‘total’ at a flat seven. The opening lines appear to be holding steady across the MLB odds boards.

Vargas stingy in Tampa Bay

Vargas notched his third straight win in Saturday’s 2-1 victory for Seattle as a 136 road dog against the Tampa Bay Rays. The 29-year-old allowed no earned runs, giving up seven hits over six innings.

Mariners outfielder Michael Saunders drove in mates Casper Wells and John Jaso for his squad’s pair of runs, giving Seattle a 2-0 lead in the top of the first frame. Jaso finished with a 2-for-3 night, while leadoff man Dustin Ackley went 0-for-4.

The tight affair’s three runs dipped below the ‘total’ of 7 ½, making the UNDER 3-2 in Vargas’ last five starts. Seattle’s four relievers held Tampa Bay without a hit in the final three innings, with closer Tom Wilhelmsen logging his staff’s save.

Mendoza ends two-loss slide

Luis MendozaMendoza picked up his first win in three starts with Saturday’s 7-3 triumph for Kansas City as a 122 home favorite against the Minnesota Twins. The Mexico native gave up all three of Minnesota’s runs, allowing seven hits over 6 1/3 innings.

Royals outfielder Lorenzo Cain went 3-for-4 from the cleanup spot, logging a team-high three RBIs. Kansas City’s Alex Gordon and Yuniesky Betancourt united to hit 5-for-9, combining to drive in three runs.

The contest’s 10 runs leaped above the closing ‘total’ of nine, dropping the UNDER to 5-2 in Mendoza’s last seven outings. Royals reliever Aaron Crow stood in for the final two frames, allowing no hits en route to his season’s second save.

Back the Royals as road dogs

Thursday’s first pitch is scheduled for 10:10 p.m. (ET). The four-game series continues Friday night with Kansas City’s Jeremy Guthrie expected to face Seattle’s Blake Beavan in a battle of right-handed starters.

I am adding the Royals and Mendoza to my baseball picks for the night’s card, looking for a mild upset to start the series.

Mendoza has put together a respectable run of recent outings, while giving up just nine earned runs in 30 2/3 IP over his five road starts. The sixth-year hurler’s last four starts away from home saw the Royals cash at 3-1, returning a +3.01 ROI as road dogs.

Vargas has been on a stingy streak, but has been overvalued at Safeco with the Mariners going 1-4 in his last five home outings. The California native gave up at least one homer in each of those starts, with the picture not looking much different against some of Kansas City’s bats.

Royals slugger Billy Butler has cracked two homers in a 5-for-11 career mark against Vargas, while coming in with a long ball in two of his last four games. Butler’s mate Jeff Francoeur ended a 0-for-12 slump with a late homer in Wednesday’s 11-6 defeat for Kansas City in Anaheim, building some momentum despite the team’s setback.

Seattle has a meager 1-9 mark in its last 10 home games against clubs with losing records, while going 1-4 in its last five series openers overall. Look for Kansas City to steal the first game of this set, edging out Saunders and Co. with just enough octane to cash.
