Lyles has rough first inning in initial outing

KISSIMMEE, Fla. -- The first time on the mound in a spring game wasn't quite what 21-year-old Astros right-hander Jordan Lyles had in mind. He pitched two innings and allowed four hits, two runs, one walk and struck out one batter in a 10-5 loss to the Braves on Monday.

Lyles, battling for a spot in the rotation, endured a 27-pitch first inning that ultimately meant he pitched only two innings, instead of his scheduled three-inning stint. He allowed a one-out single in the second inning, but got two quick outs.

"I wasn't expecting too much with that first outing," Lyles said. "Today, the command wasn't there. That's to be expected the first time out facing live hitters. I made a couple of pitches to get a couple of ground balls, but they found holes. Hats off to them. It really came down to me falling behind guys and throwing too many pitches in that first inning."

Zach Duke, who's also pitching for a rotation spot, pitched three innings in relief and allowed three hits, one run and two walks in his debut in a Houston uniform.

"He kept getting himself in trouble and getting himself out of trouble, too," said Astros manager Brad Mills, who said Duke will get to start a game soon.

Lee set to make spring debut on Tuesday

KISSIMMEE, Fla. -- Astros first baseman Carlos Lee will make his Grapefruit League debut on Tuesday against the Mets at Osceola County Stadium. Lee wasn't in the lineup for the first three games because of a mild right hamstring strain.

"We've got him in the lineup," Astros manager Brad Mills said.

Lee tweaked the hamstring while working out this winter in his native Panama and needed a few more days at the start of spring camp to get game ready. He said Monday he ran the bases and did wind sprints on Sunday without any issues, giving him the green light to play.

Meanwhile, catcher Humberto Quintero (back/hip) is still a few days from getting into the lineup, Mills said. Third baseman Jimmy Paredes (wrist) and infielder Angel Sanchez (back) continue to progress and were scheduled to take batting practice on Monday. Mills said they're tentatively slated to take live batting practice on Tuesday.

Sanchez has been doing drills with his teammates for the past few days and is anxious to get into games. A non-roster invitee this year, he's playing for a spot on the club. He injured his back helping his mother move boxes down stairs.

"I worked a lot in the offseason to be ready to play here," Sanchez said. "I can't wait."

Bourn faces former 'mates for first time

KISSIMMEE, Fla. -- For the first time since he was traded to the Braves last July, Houston native and former Astros center fielder Michael Bourn faced his old team on Monday. Sure, the game didn't mean much, but Bourn got a chance to reunite with former teammates.

"It's Spring Training and you're going about your business, and trying to see the ball and get at-bats and work on little things," said Bourn, who went 1-for-4 with a triple and an RBI.

Bourn was traded to the Braves last year in the deal that brought Jordan Schafer -- Atlanta's former top prospect -- to Houston, as well as three Minor League pitchers. Schafer started in center for the Astros and went 1-for-3 with a run scored.

"It's just another Spring Training game and trying to get ready for the season. But it will be fun to go against my old teammates," said Schafer, who worked out with Martin Prado and Matt Diaz of the Braves in the offseason.

Bourn caught up with several of his old teammates prior to the game, and took some good-natured ribbing from fellow Houston native and close friend, Jason Bourgeois.

"Jason was over there talking noise to me," Bourn said. "Everybody else [said], 'Hello,' and asked how I was doing and I asked how they were doing. I didn't get to see everybody, but I got to see most people. They treated me well over there. I have nothing bad to say. They gave me an opportunity to play for four years, and now I'm with the Braves. That's that."

Moore looks to stick in big leagues

KISSIMMEE, Fla. -- In addition to George Springer, Jason Castro, Delino DeShields Jr. and Brian Bogusevic, the Astros have another former first-round Draft pick in camp this year -- infielder Scott Moore.

Moore, signed to a Minor League contract and invited to camp in November, is a veteran of 80 Major League games over parts of four seasons with the Cubs and Orioles. He's played the majority of his Minor League career at third base, but also has appearances at first, shortstop, second and in the outfield.

"Obviously, you want to come into camp with the mindset of wanting to make the club. But it's still early, and I want to take advantage of the opportunities when I'm out there and let it play itself out," said Moore, who was drafted by the Tigers in the first round in 2002. "It feels like yesterday I was drafted. It's gone by quickly."

Moore, a left-handed hitter, owns a career .223 batting average with six doubles, seven home runs and 27 RBIs in 184 career Major League at-bats, and he's got 119 career Minor League home runs. He spent all of last season at Triple-A Iowa in the Cubs' organization and hit .295 with nine homers and 53 RBIs.

"I'm still holding out hope at some point I'll get to the big leagues and stick," Moore said.
