The Seattle Mariners and San Diego Padres played the first of a three-game set Tuesday at Petco Park in San Diego. The series doubles as the first leg of the Eddie Vedder Cup, which is awarded to the winner of the season series between the Mariners and Padres.

Both players entered Tuesday's game on respective win streaks and coming off four-game sweeps against division rivals.

Something had to give Tuesday, and unfortunately it was Seattle (8-10).

Here's several takeaways from the M's 4-1 loss against the Padres:

In their four-game sweep against the Houston Astros, the Mariners averaged 7.25 runs a game.

Seattle's one run mustered against San Diego came via an RBI sacrifice fly hit by designated hitter Dominic Canzone in the top of the second inning.

The Mariners mustered four hits Tuesday: all singles. Left fielder Randy Arozarena had two, first baseman Josh Naylor had one and right fielder Luke Raley had another.

The M's went 0-for-2 with runners in scoring position against the Padres and stranded six.

In seven road games this season, Seattle is 1-6 and is averaging two runs a game.

The Mariners haven't been able to find their bats on the road, with the exception of an 8-7 loss against the Los Angeles Angels on April 5. 

Seattle hasn't been able to find its bats the way it has at home and it will likely need to find the form soon.

Mariners starting pitchers Bryan Woo finished with a quality start but it wasn't the cleanest outing by his standards.

Woo struck out three, walked one and allowed three earned runs on eight hits in seven innings pitched. He also was called for a controversial balk in the bottom of the second inning but it didn't end up leading to runs.

The three runs allowed by Woo were an RBI single hit by right fielder Fernando Tatis Jr. and a two-RBI single hit by shortstop Xander Bogaerts. Both hits came in the bottom of the third.

Tuesday marked Woo's third quality start of the year in four outings and the third time in a row a Seattle starter has pitched through the seventh inning.

Despite the fact Woo made his first career All-Star game last year, the team's starting rotation still took a step back from its usual form due to the litany of injuries that caused four hurlers to miss time.

The rotation is still not completely healthy. Bryce Miller is nursing a left oblique strain. But, it looks like it has finally returned to its normal form when it was considered arguably the best collection of starting pitchers in baseball.

The Mariners will try and force a rubber match against San Diego in Game 2 of the series at 6:40 p.m. PT on Wednesday. Emerson Hancock will start for Seattle and Randy Vasquez will start for the Padres.
