Houston Astros Player News: Last 24 hours, All Positions

News: McCullers (elbow) faced hitters for the first time this spring, throwing a live batting practice Friday, Brian McTaggart of the Astros' official site reports.
Impact: McCullers, who began and ended last season on the disabled list, missed the final month of the 2016 season due to elbow discomfort. The right-hander threw all of his pitches Friday -- the four-seam fastball, curveball, sinker and changeup -- and was pleased with the results. He'll throw two more BP sessions this week before making his Grapefruit League debut. When not on the DL last season, McCullers went 6-5 with a 3.22 ERA in 14 starts.
News: Martes has changed the grip of his changeup from a two-seam to a four-seam grip, Jake Kaplan of the Houston Chronicle reports.
Impact: Martes impressed several hitters during his first live batting practice of the spring Friday, using his mid-90s fastball, power slider and a still-developing changeup. The 21-year-old right-hander has been receiving tutoring from former Astros ace Roy Oswalt, who spent time this week working on Martes' changeup, a pitch Oswalt believes is pivotal to the prospect's development. Martes had been throwing a two-seam changeup despite not throwing a two-seam fastball. Oswalt suggested the four-seam changeup to better deceive hitters.
News: Reddick will make his spring debut Monday, starting in right field against the Mets in Port St. Lucie, Jake Kaplan of the Houston Chronicle reports.
Impact: Reddick, who signed a four-year deal with Houston during the offseason, is a Gold-Glove-caliber defender in right field. As such, George Springer, who played 148 games in right last season, will move to center field.
News: Springer will make his first game appearance Monday against the Mets in Port St. Lucie, Jake Kaplan of the Houston Chronicle reports.
Impact: Springer, who played 148 games in right field last season, will start in center field against the Mets. He's expected to play in center in 2017 as Josh Reddick, a free-agent acquisition during the offseason, will man right field.
