Seattle Mariners battling a season-long case of the weekend woes

The Seattle Mariners could easily be in first place in the American League West if they could just find a way to win on the weekends.

The Mariners have put their fans through an up-and-down season, but in a weird way. They are 28-15 from Monday to Friday, but 6-14 on Saturday and Sunday after a pair of tough losses to the Texas Rangers the past two days.

The Mariners were a strike away from a 1-0 win on Saturday night, when Prince Fielder homered against Mariners closer Steve Cishek to tie and Rougned Odor hit a game-winning home run in extra innings against lefty reliever Mike Montgomery (who had pitched the most innings of anyone who hadn’t allowed a home run all season).

That game was somewhat reminiscent of May 14 (a Saturday), when the Mariners took a 7-6 lead into the ninth inning against the Los Angeles Angels, but Cishek lost it when he allowed a three-run home run to Albert Pujols.

On Sunday, it appeared the Mariners would get the tying run to the plate in the ninth inning, when Robinson Cano hit a ball into the right-field corner. But Cano was thrown out at second by Nomar Mazara to end the game. It wasn’t the first time the Mariners lost a game when a baserunner was thrown out. On May 28 (another Saturday), the Mariners had two runners thrown out on the bases on the same play (a pitch in the dirt) in a one-run loss to the Minnesota Twins.

The other common thread to this is home-field issues. The Mariners are not the same team in Safeco Field as they are in other ballparks. They are 15-18 at home (despite outscoring their opponents 150-132) and 19-11 on the road. They are 5-10 in one and two-run games at home, 6-5 in them on the road.

As would be expected, three of the Mariners' best power hitters-- Cano, Kyle Seager and Nelson Cruz -- don't have the same sort of power success in spacious Safeco as they do elsewhere. They've combined for 19 home runs in 371 at-bats at home, but have 25 in 355 at-bats on the road.

One of the other big (and somewhat inexplicable) differences is the Mariners' bullpen, which has a 2.44 ERA on the road but a 3.82 ERA at home.

As such, the team's Pythagorean record (an estimate of what their record should be based on runs scored and allowed) is 37-26. The Rangers' mark would be 35-28. Alas, the Rangers are now five games better in the actual standings.

The good news for the Mariners? They head on the road for 10 games, though it’s a challenging trip with the Tampa Bay Rays, Boston Red Sox and Detroit Tigers looming.
