Carlos Zambrano SP PHI 10 Months

Carlos Zambrano left Friday's start with Triple-A Lehigh Valley with an apparent arm injury.

Zambrano allowed four runs (one earned) on three hits and a walk before exiting. The Phillies have been considering whether to call-up Big Z prior to his July 1 opt-out date, but an injury would obviously change things.

Phillies general manager Ruben Amaro indicated Monday that Carlos Zambrano is unlikely to be promoted before July 1, when he can exercise the opt-out clause in his contract.

"This last start wasn't as good as the one prior," Amaro said. "He's been inconsistent. We'll see." When asked if Zambrano can get major league hitters out, Amaro replied, "He can, at times. Right now, I don't know if he can do it consistently." Big Z holds a 2.89 ERA with 29 strikeouts over 33 1/3 innings covering six minor league starts, but it sounds like the Phillies have more faith in Jonathan Pettibone at the moment. Zambrano shouldn't have trouble catching on elsewhere if he opts out.

Carlos Zambrano struck out six over seven scoreless inning for Triple-A Lehigh Valley on Tuesday.

Big Z permitted five hits and walked one. The veteran righty now holds a 0.95 ERA over five starts in the minors and could be added to the Phillies' rotation this weekend. Jonathan Pettibone would lose his rotation spot is Zambrano is called up.

Carlos Zambrano's start with Double-A Reading on Friday was rained out.

Big Z had 10 1/3 scoreless innings over his first two starts with High-A Clearweater and was slated to move up to Double-A on Friday. However, he'll now be pushed back to Saturday. The veteran right-hander could soon join the Phillies' starting rotation.

Carlos Zambrano will make his next start at Double-A Reading on Friday.

Big Z tossed six scoreless innings in his second start with High-A Clearwater on Sunday. He's now been unscored upon in 10 1/3 minor league innings and could possibly be added to the Phillies' rotation if Friday's outing goes well.

Carlos Zambrano threw six scoreless innings in his start Sunday with High-A Clearwater.

According to MLB.com's Adam Berry, Zambrano showed good command and touched 90 mph with his sinker. He's expected to make at least one more start before the Phillies consider him for a promotion. Zambrano can opt out of his minor league deal on July 1 if he hasn't been added to the 25-man roster.

Carlos Zambrano will need at least two more minor league starts before possibly joining the Phillies.

Zambrano threw 4 2/3 scoreless innings in his first outing for High-A Clearwater Tuesday, but general manager Ruben Amaro wasn't overly impressed. "He threw OK," Amaro said. "I don't think he lit the world on fire. But he's gaining arm strength. It was a little better than his last outing. He's getting stretched out. We'll see where he goes from here." John Lannan (quad) could be ready to join the Phils before Big Z, so it remains to be seen where he fits in with the big club.

Carlos Zambrano threw 4 2/3 scoreless innings on three hits and two walks in his first outing for High-A Clearwater on Tuesday.

He struck out a pair. The Phillies haven't revealed a timetable for Zambrano possibly joining their rotation, but Matt Gelb of the Philadelphia Inquirer thinks the righty might just need one more minor league start. He would replace Tyler Cloyd in the rotation.

Carlos Zambrano will make his first start with High-A Clearwater on Tuesday.

Zambrano signed a minor league deal with the Phillies earlier this month and is coming off two strong outings in extended spring training. The veteran right-hander had a mediocre 4.49 ERA with the Marlins last season, but could be an option for Philadelphia's rotation before long.
