Instant replay and observations from the Rangers' 5-0 loss to Seattle on Saturday at Safeco Field:

What you need to know: This one was more about the process than the result. The process: The building of a championship rotation. In that regard, the debut of Andrew Cashner appeared to be a step in the right direction. He took a shutout to the sixth inning on a night when five innings might have been just about what the Rangers could realistically have hoped for.

Dude of the day: Joey Gallo broke up James Paxton's no-hitter with one out in the sixth by doubling on a full-count pitch into the right field corner. He also grabbed third base on a ball in the dirt that really didn't get away from Mike Zunino. Gallo has had two-strike hits twice in the last three days and has played sharp defense at third base. It's been a good week in his development.

Rotation report: Andrew Cashner's willingness to pitch inside had to make manager Jeff Banister very happy. Banister has been preaching it to his pitchers for more than two years. Cashner had no fear of doing it in his first start and got a key double play by coming in against Danny Valencia in the second inning. Cashner went to the sixth inning with just 69 pitches, an average of 13.8 per inning. He also worked quickly on the mound.

OTHER STUFF

Spring has sprung: All the feel-good of Delino DeShields' impressive spring training has seemed to slip away quickly. He's 0 for 9 in three starts over the first 11 games of the season. Most distressing: Six strikeouts and no walks. It's hard to create playing time for yourself when you aren't having success and it's hard to have success without finding a rhythm.

Burning down the Haus: Rule 5 pick Mike Hauschild could not close out the sixth inning without further issue for the Rangers. He gave up a three-run homer to Taylor Motter. Hauschild has given up very loud three-run homers in consecutive games. He's allowed runs in each of his three outings. With a thin bullpen, it may tax the Rangers to keep a Rule 5 pick who isn't having success. The Rangers would have to offer him back to Houston before they could send him to the minor leagues.

All or nothing: The Rangers remain something of an all-or-nothing offense. They have played 11 games. In seven of them they've scored five or more runs; in three one or fewer. This also seems a little bit troublesome: The Rangers have yet to win a game in which they have scored fewer than eight runs.
