Brady's Spin: George Kirby's First Start For Seattle Mariners Was Better Than Final Stat Line

Seattle Mariners starting pitcher George Kirby made his much-anticipated season debut on Thursday night against the Houston Astros.

Shut down since March because of shoulder inflammation, Kirby lasted just 3.2 innings, giving up five earned runs. He walked a batter, hit two and struck out four. The Mariners lost 9-2.

Despite the rough final stat line, the outing wasn't all that bad, as we discussed on the most recent Refuse to Lose podcast:

At the end of the day, what are the things that matter most? One, how does he feel subsequently? That's going to be number one. Two, how is his velocity? Well, he was up to 98 mph. He was 95 to 98 fairly consistently. That's good. How were the movement on his pitches? I thought pretty good. He had the two-seamer, the sinker, the slider had movement. The splitters that he threw had movement. He was not great location wise, but those are all feel pitches, or at least the slider and the splitter are feel pitches.

Remember, he made, what, one spring training outing or two spring training outings and three rehab starts? He hasn't had a whole lot of time, so I'm not going to be too concerned about his lack of feel at this point. He threw strikes mostly. Now, he hit Pena, twice, and he did have a walk at the end, but by and large, I thought he threw strikes. The velocity was good, movement was on his pitches. He just has to find a way to put guys away. And that, I feel like has been a relatively consistent issue for the Mariners starters, in that they're doing what you want them to do in terms of throwing strikes and getting ahead. What they're not doing is striking enough people out consistently.

The Mariners will finish out the series with the Astros on Sunday before having an off-day on Monday.
