BRADENTON -- Tyler Glasnow gave up a run Tuesday.
Pitchers give up runs, so that normally isn't big news.
Glasnow, however, considered one of the best prospects in baseball, entered the morning game against the Palm Beach Cardinals on an extremely abnormal streak. He hadn't allowed a run in more than a month.
Rather than lamenting the end of his string of zeroes, Glasnow, Bradenton's hard-throwing righty, looked at the positives. He went a career-best seven innings while allowing just one hit during the Marauders' 2-1, 12-inning loss to the Cardinals during a camp day at McKechnie Field.
And when Glasnow did allow a run -- his first since May 22, a span of 28 innings -- he minimized the damage, which may not have happened in the past.
"That's the thing I've kind of preached all year, not going out there and thinking of mechanics and 'I've got to do this, I've got to that,'"
Glasnow said. "When I just clear my mind, take a breath and just let it rip, really, it works out well for me."
Glasnow walked the first two hitters in the fourth before Alex Mejia's sacrifice bunt put runners on second and third with one out. Nick Martini's flyout to center plated a run, but Glasnow quelled the threat by striking out Bruce Caldwell.
"We spend a lot of time on his routines, both his pregame and his bullpen routine in between starts," said Justin Meccage, Bradenton's pitching coach, "and then his pre-pitch routines. That's probably 90 percent of our time, just working on the mentality.
"The fourth (inning), I thought some things were going to start speeding up. It did; he walked the first two guys. And then he got it together."
Glasnow didn't allow a hit after the third inning, didn't walk anyone after the fourth and finished with six strikeouts. Illderamo Vargas reached on Glasnow's fielding error in the fifth, but he was caught stealing second by Bradenton catcher Jacob Stallings.
"I remember the first time I caught him in spring training, it was kind of all over the place," Stallings said of Glasnow. "Now he can throw all three pitches for strikes with a lot of regularity. With his stuff, it makes him so hard to hit."
At 84 pitches after six innings, Glasnow was sent out for the seventh for first time since his days at Hart High in Santa Clara, Calif. He responded with a perfect inning, ending his day at 100 pitches and lowering his earned-run average to 1.62.
The Cardinals snapped a 1-1 tie in the 12th on Caldwell's two-out double. Jonathan Schwind's fourth-inning triple accounted for the only run for Bradenton (39-36, 4-2).
Ranked baseball's 23rd-best prospect by MLB.com, Glasnow is limiting opponents to a .144 batting average.
"Before, if I were to maybe give up a run -- say, last year -- things would snowball, and I'd walk guys and get really flustered and think of what was going to happen," Glasnow said. "I just think the big thing this year during my roll has been a big mental thing."
